Combining Two Variables Together To Make A New One?


Aug 21, 2007

Supposing I have one variable, $file=filename, and a second variable, which is $number='99'; How can I make a third variable, $fileno which will equal filename99? I'm guessing it's not as simple as $fileno=$file$number...

Combining Form Variables

I have a form on which a user can select a date in one field and a time in another. I need to combine these two variables into a single datetime variable to put in the database. I've looked all over and can't seem to find any good info on this. Everything else I am sending to the database works just fine. Here is what doesn't work [it throws a parser error]:

<?php
$db_host = "*****";
$db_user = "*****";
$db_pwd = "*****";
$db_name = "contentdb";

mysql_connect($db_host, $db_user, $db_pwd) or die('Could not connect to mysql server: '. mysql_error());
mysql_select_db($db_name) or die('Could not select database: '. mysql_error());

$publishdatetime = $_GET["publishdate"] + $_GET["publishtime"];

$result = mysql_query("insert into main_articles (publishdatetime) values ('$publishdatetime');

mysql_close();
?>

Combining Variables In All Combinations

I am creating an app that will take a 3 lists oy words or phrases (entered in a textarea form element) and produce all combinations of th lists.

For example, if you enter the words
"buy" and "sell" in the first box,

"blue" and "red" in the second box and

"widget" and "widgets in the third box

script would generate all combinations of these words like "buy widget" "buy widgets" "buy red widget" "sell red widget" "buy blue widget" "sell blue widget" "buy red widgets" "sell red widgets" "buy blue widgets" "sell blue widgets"

I think I will turn each list into an array (explode()), and then process, and then take the completed list an implode() back to a variable. I'm just not sure how to process the combinations.

Make Classes Remember Their Variables?

I have this class that manages stuff like registering, logging in, member-only access, general stuff like that. It have a few variables that are accessed throughout the site. However, when I reload or visit another page, it forgets all of the variables and I have to reset them. To do this, I have two session variables called loggedIn and username. If loggedIn is true, I use a function to get all of the info about username and I reset my variables to the info I retrieved. Should I continue on with this or no?

Get And Edit GET Variables In Order To Make Hyperlinks

Let's say that I have URL like somefile.php?sort=id&way=desc.

I want to write a function (or use already made one) that would let me add next variables to URL and set which I want to delete.

I thought about something like function editGetVar("$add","$leave") where $add would be array with new variables to add to URL and $leave would be array with variables that must stay in URL.

Example:

somefile.php?sort=id&way=desc&buyer=retailer

and I want to delete "buyer" and add "action", then the a href would look like this:

<a href="somefile.php?sort=id&way=desc&action=edit">

Make PDOStatement->fetchObject Not Use Non Member Variables?

Lets say I have a class like this:

Class User {
var $id
var $name;
}

And I run a query using PDO in php like so:

[code]....

If I vardump my user object it has all kinds of other fields in it that I have not defined in the User class. Obviously I could make my query specific so that it only gives me back the fields I need/want. But if I don't want to do that is there any way to make this work the way I want it to? I like the idea of fetchObject, because it's one line of code to create this object and set member variables for me. I just don't want it to set variables I haven't defined in my class.

Make $_SESSION Variables A Global In A Function?

i'm have a particular function where it creates session variables, yet after using this function i want to immediately use these session variables

now I realize the only way to "use" variables that are made inside of a function is to make the variable a global variable so it can be used outside the function

so i did this:
global $_SESSION['userid'];
global $_SESSION['username'];
global $_SESSION['userlink'];
global $_SESSION['userifnewmsgs'];
global $_SESSION['userrank'];

however there are many instances when !isset($_SESSION) , when the session variables are not already set

i run this function when the sessions are not set and I get this:
Parse error: parse error, unexpected '[', expecting ',' or ';'

what's going on and how can I fix it?

Make A Button That Would Pass The Form Variables To Other Page

here's some code that's at the top of my page, a form later in the page posts the variables back to the same document and then updates the database. How do I make the page so that when the form is submitted it posts the info to the same page and then passes the same variables that were just put into the database to a page named view.php? or another way that would work was if there was a preview button next to the submit button that passed the variables, but the form action is set to PHP_SELF, so how would I make a button that would pass the form variables to view.php and not to itself?

Make Global Variables Available To An Included File Within A Function?

i need to include files within a function, and files use lots of variables defined earlier in the script.
using global is not an option because it is impossible to say which variables will be used in included files.
the only one real solution is to make all global variables accessible in function, something like:

function finc($file)
{
foreach($GLOBALS as $k=>$v)[code]....

but it won't be good when using lots of files with lots of variables, so is there any better way to do it?
