Storing Php Code As A Variable

May 19, 2007

I would like to store php code into a variable, heres an example:

function test ($var) {
$var; //I also tried echo $var;
return;
}

$string = "echo "test" ";
test ($string);

When it works, it will only output "echo test", instead of just "test".

Preg_replace - Storing The Code In MySQL

Oct 6, 2007

I am putting a site together for my own reference, to take notes on php code, so I can go back later on and see how it is done. I am storing the code in MySQL. Obviously when I insert my code in to the database and pull this back out nothing is displayed.

For instance in this forum their is a small php tag you can use to enclose your php code before submitting. How does this work so when it displayed it looks like this below.
PHP Code:

<? echo "For example I enclosed this in the PHP tags before submitting to the database"; ?>

Storing Code In MySQL Column?

Jul 29, 2010

I'm working on a pet project and I'm looking for some hints/directions regarding best practices. I'm rolling my own blog that will display code snippets....similar to the code examples used in these posts and millions of others around the interweb. The code snippets are for display only and will never be retrieved and executed. I plan on using PDO and prepared statements for the database interactions. Is it ok to store this type of code in a database? Will PDO and prepared statements be sufficient for inserting into and selecting from columns that contain code snippets?

Storing Php Code In A Database (for Use With Eval)

Jun 6, 2007

I've got a need to store php code in my database (among the text) that I parse out and execute with eval(), and had it encrypted at first, but have seen now that the decryption process (it's a custom encryption/decryption function set) adds a good half second or so to an already-slow load time. Given that I've taken fairly adequate steps to securing my database, do you suppose there would be a problem storing the code as plain text to shave off that extra time?

Storing And Retrieving Code In Mysql Database?

Nov 10, 2010

I am working on a kind of CMS for my own website which no one else will be using but me as a way of improving my php skills, and am having problems with retrieving data from the database that holds both text and php code. I have searched the web and found that i should be using eval() for the code to be executed before it is send to the browser but cannot get it to work and can't find my mistake(s). the php code will always be the same, and is supposed to retrieve the id number of a page to use in a link (and works fine when tested by loading the code directly without retrieving it from the database) this is an example of data stored in the database

Code:

[Select]The<ahref="page_builder.php?id=<?php echo $page->id('mines_DwarvenMines') ?>">Dwarven Mines</a> have a great selection of Ores,... Of course when I leave it like this, hovering over the link in my page will show exactly that and lead to nowhere

Code: [Select]localhost/page_builder.php?id=<?php echo $page->id('mines_DwarvenMines') ?>

Most of these links appear in tips given at the end of the page and are processed as followed

Code:[Select]$questtips = $quest->getQuestTips();
$tips = "";
if ($questtips == "none")
{

[code]....

I have tried all sorts to get the code to be executed when retrieved from the database before being send to the browser so that this particular link would say [URL[ but I cannot get it to work, though I suspect it is fairly easy. I suspect I would have to store the data in a different format in the database? And how exactly do I use the eval() function in my case?

Storing A Session Variable?

May 9, 2010

I have 5 forms. Each is an HTML page, that when the submit button is pressed, posts the data to a PHP page for processing (the viewer just gets taken to the next form). On the PHP page, the data is formatted and sent as an email. The problem is that the email address of the viewer is only asked for and entered on the first form, yet each of the five forms will send an email, and will need that viewers address as an $EmailFrom variable.

I wanted to pass just the email address from the first form where it is physically entered, to each of the other forms. I don't think that a "GET" method will work since there is way too many fields on the form and it will be too much data to pass in a url. I thought that storing a session variable would be my best bet. My thoughts were to put it in the first HTML page, and then destroy it in the last PHP page. But I have never done this, and have not had any luck yet. I put this code on my first HTML page, in between the DTD and the HTML tag:

<?php
session_start();
?>

Then I put this on the bottom of my PHP page:

$_SESSION['from']= $EmailFrom ;

Then on each of the remaining PHP pages, I entered this at the top:

$EmailFrom = $_SESSION['from'];

But the email address I see on the actual email I receive is:

"INVALID_ADDRESS@.SYNTAX-ERROR." <INVALID_ADDRESS@.SYNTAX-ERROR.

If I do something like:

Storing Variable In Mysql

Jun 11, 2007

i have stored a variable into my database, i would like it to be a variable instead of being plain text, eg. i store $teazer in the db right, and then before i read the database i populate the vaiable $teazer rite, then i want it to come after a certain paragraph on some other page, so i figured the way to do it was to put it inside the db and it will be invoked by that variable.

Storing A Variable From A Function?

Dec 3, 2010

This seems really straight forward but I can't figure out why it's happening.  As a part of an account registration script, I'm randomly generating a password using a function called, generatePassword($length,$strength);

I hash the password (md5) before putting it in the database but I also email the non-hashed version to the user.  My problem is that each time I call the variable, it generates a new password so the one in the database does not match the one received by the user,

$user_password_plain = generatePassword($length,$strength);
$user_password = md5($user_password_plain);

Is there a different way to store the variable so that I can access it later in the script and it will be the same?  I tried using a session variable but that didn't seem to work either.

Storing An Object In A Session Variable

Apr 10, 2003

Is it safe to store an object in a session variable, allowing it to be unserialized without the class definition loaded in some cases, then, later, unserialize with the class definition loaded and continue using normally? e.g.

page 1: load class definition, start session, create new object, store in session variable

page 2: start session, don't access object stored in session

page 3: load class definition, start session, access properties / methods of object stored in session

The PHP manual says

It is strongly recommended that you include the class definitions of all such registered objects on all of your pages . . . If you don't and an object is being unserialized without its class definition being present, it will lose its class association and become an object of class stdClass without any functions available at all . . .

What I am wondering is whether that explanation should be qualified by "for that request". That is, does unserializing the object without the class definition loaded only cripple the object for that request, or does it permanently damage it when it is reserialized?

I tried a quick, simple test by creating three pages that behave as described above, and it appeared to work fine.

Storing Part Of A String In A New Variable

Apr 24, 2007

I have a string (usually a url as it happens) which I need to get a certain part of and then store it in a variable. i.e.

my strings are like this: "http://www.foo.com/directory/add/00102020/do.php?stuff"
"http://www.foo.com/directory/add/00301090/do.php?stuff"

So basically the URL or String are the same except for the numbers change. It is the numbers I want to store in a new variable.

I think I need to use regular expressions and preg_replace but just can't get my head around how!.

Storing A Loop As A String In A Variable?

Oct 8, 2010

I have a problem storing a PHP loop in a variable.

The loop is like this:

for( $i = 1; $i <= 10; $i++ ) {

echo $i . ' - ';
}

for this it's OK for an echo or print as it will produce:

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 -

now I want to store the whole loop in a variable like $my_var which means:

echo $my_var;

which will produce:

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 -

the whole idea is that I want to make the loop, store it as a string in a variable $my_var, than use it later in my script.

Storing Data From Mysql As Variable?

May 18, 2009

I got my code (below) basically it is to resend user activation email if they for some reason or other did not get it first time etc. It sends the email and everything etc... what i need to do it not only get the user email address which i can do no problem but to also fetch the user activation key and username from the DB. Now if you look in my code i put

$query = ("SELECT * FROM userinformation WHERE `email` = '$email', `username` = ' ', `activationkey` = ' ' ");

the email part of it works as it checks the email address the user put in form against the DB but the activationkey and username part it does not get from DB. I need to get the activation key from DB and username to as it needs to be stored in a variable like the email so it is sent along with the email. Problem is like i said the activation key and username is not being fetched from DB.

I have set up a db that is temporary so each time information is entered it adds it to the db then once registration is finalized, it will add the user to the permanent db. My question is, if I assign an ID after the first of 3 forms is submitted and store that in a variable, after the page changes will the variable retain it's value or do I have to store it somewhere in the page to reference it? I'm doing this so I can add the following information to the correct client but I'm learning PHP.

Storing Value Into Variable And Display In Wordpress Loop

Apr 2, 2011

I am using a wordpress plugin called advanced custom fields that basically creates custom write panels on the backend, and gives you php shortcodes to insert into your template files. It looks like the following:

<?php echo get_field('video-slug'); ?>

This will return a slug value that I need for the wordpress loop. My wordpress loop is as follows:

<?php $loop = new WP_Query( array( 'post_type' => 'videos', 'artist_name' => 'HERE IS WHERE I WANT THE SLUG', 'post_child' => 0, 'posts_per_page' => 5 ) ); ?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<li>
CONTENT HERE
</li>
<?php endwhile; ?>

the first line of the loop requires that slug that was created above. I cannot simply enter <?php echo get_field('video-slug'); ?> into the loop because it will cause a php error. Perhaps I can create a variable and then put that into the loop? Basically, I need to know how to take a php generated value, perhaps store it in a variable, and then use that variable in my loop as follows: 'artist_name' => '$variable' or something like this.

function jsonAction() {
//Do DB update
if(db update was ok) {
$response = array("completed" => true, "html" => $this->render("message"));
} else {
$response = array("completed" => false);
}
echo json_encode($response);
}

What seems to be happening right now is that the render method echos the rendered value instead of returning it.

Storing Database Connection In A Session Variable?

May 21, 2011

Many of us have written PHP applications that require databases; mostly MySQL, but I have often used very small MS Access databases for people less technically capable so they can download an tweak them/save backups/etc. on their own (whether this is correct or not, I have no idea).

What I notice, is a lot of time is spent connecting and running some of the same queries. Because of this I had an interesting thought: Storing the connection and possible result sets that are mostly static in a $_SESSION variable to reduce the burden as the user navigates the site.

Obviously doing so requires a lot of consideration. Things like closing the connection when the session is destroyed is just the start.

My question boils down to: Is this really something possible? And if so, what things should I be aware of (besides session fixation, as it is its own problem that applies to all sessions)?

Storing Values In Session Variable And Doing Calculations

Oct 26, 2010

I am working on a PHP web form and I have a very simple situation I guess, I have a variable named: $MyVal
When I do

print_r($MyVal);
To see whats inside, I get:

SimpleXMLElement Object ( [0] => 8.23 ) Now I am assigning this variable into a session variable so that I can do calculations with it. So I assign:

$_SESSION['MySesVal'] = $MyVal;

But after assigning to session variable, when I do my calculations:

$finalValue = $_SESSION['MySesVal'] * 4;

I get 0. So is it because the actual $MyVal variable has some XML stuff as:

SimpleXMLElement Object ( [0] => 8.23 )

So what is the right way to properly assign $MyVal variable to a session variable to do calculations.
