I got an associative array and I need to find the numeric position of a key. I could loop through to find it but but is there a better way build into php?

'blue' => 'nice',
'car' => 'fast',
'number' => 'none'
);
// echo (find numeric index of $a['car']); // output: 1

Multidimensional Mixed Associative/numeric Array Shifting?

May 18, 2009

i have an issue i need to fix sooner than later. if i had the time to rewrite the entire script i would, but such is the life of a programmer, right? anywho, i've taken over a project and i have a multidimensional mixed associative/numeric array like so:

Array
(
[item1] => Array
(
[dataset] => Array()

[code]....

a few things that may help make this happen is that i know that the dataset index will always be the first index in the itemX index and the key will always be 'dataset' and the others will all always be numeric indexes. is there anyway to do this in php? the fact that it's a mixed array is throwing me. i can't have the numeric indexes getting reset and starting at 0. it doesn't matter if they're order is shifted, only that they all come before the 'dataset' index.

Change An Associative Array Into Indexed Array / Get Zend_Table_Row_Abstract As Non Associative

Jun 30, 2009

I was wondering if there was either a function or an easy way to change an associative array into an indexed array. To elaborate, I'm using the Zend framework, and I've got a point in my site where I take out a row of an SQL table as an associative array. I've passed it to javascript via an echoed in JSON. However, I've noticed that I can see the names of my database's columns in Firebug. Having outsiders know the names of your tables and columns is a big security no-no, so I'd like to change it from

SQLarray[user_id]
SQLarray[block_id]
SQLarray[b_price] etc.
to
SQLarray[0]
SQLarray[1]
SQLarray[2] etc.

Is there a good way to do this? It would also work to be able to have a Zend_Table_Abstract->fetchAll() return a non-associative array, but I don't think that's possible.

Javascript - Converting A Associative Array To A JSON Associative Array

Mar 9, 2010

I am converting a look-up table in PHP which looks like this to JavaScript using json_encode:

AbilitiesLookup Object
(
[abilities:private] => Array
(
[1] => Ability_MeleeAttack Object
(
[abilityid:protected] =>
[range:protected] => 1
[name:protected] => MeleeAttack
[ability_identifier:protected] => MeleeAttack
[Code]......

And in JSON, it is:

{"1":{"name":"MeleeAttack","fof":"2","range":"1","aoe":[null,"1","1"],"fp":"0","image":"dummy.jpg"},....

The problem is I get a JS object, not an array, and the identifier is a number. I see 2 ways around this problem - either find a way to access the JSON using a number (which I do not know how) or make it such that json_encode (or some other custom encoding functions) can give a JavaScript associative array. (Yes, I am rather lacking in my JavaScript department).

Note: The JSON output doesn't match the array - this is because I do a manual json encoding for each element in the subscript, before pushing it onto an array (with the index as the key), then using json_encode on it. To be clear, the number are not sequential because it's an associative array (which is why the JSON output is not an array).

Equivalent Of Delphi - Convert The Object To An Array And Then Refer To The Associative Elements In The Array?

Dec 6, 2009

Is there a PHP way to do the equivalent of the following Delphi snippet

with someObject do
begin
   x:=objPropA;//some stuff with objPropA
end;

Apart from reducing the verbosity of code it also reduces the possibility of typo errors.  The best I have managed is to convert the object to an array and then refer to the associative elements in the array. This works for me because I ensure that I am only handling simple PHP objects - i.e. ones which do not have objects as properties in turn. However, given just how neat PHP is I am sure that there is a better way.

Long Name For An Associative Array / Array If To Take Into Account Performance Of The Application?

Jun 30, 2010

I have a function which must return one dimensional associate array, like $user_info[$index]=value where $index is a string which consist of

user_id
full_name
photo_file_name

for example, my associative array could look like $user_info['user-123456789~~Bill Gates~~bill_gates.png']=$value. I need user_id, full_name and photo for another needs, in order to know whose value is this and what is his full name, etc.So, the questions that has risen are following:

Is it OK to have such an array if to take into account performance of the application?If it is bad (I think that it is bad idea) so how can I solve my problem in this case.

Additional info. This function retrieves user information into this associative array and returns this array. Further, my application stores it in a session in order to address it and retrieve information right from the session variable, not execute once again a query. And finally the reason I need one dimensional array is that I use a function array_diff where one of the arrays are $user_info array.Note, Take into account that one user could have 1 or many values.

Sorting Associative - Array In The Exact Order Of The Content Of Another Array

Jan 15, 2010

I need to sort an associative-array in the exact order of the content of another array. The Arrays are retrieve by 2 separate sql-requests (stated below). The requests could not be combined to only one request, so I have to sort the second array into the order of the first one. These are the arrays:

#Array which contains the id's in needed order
$sorting_array = array(1,2,3,8,5,6,7,9,11,10...);
#Array which contains the values for the id's, but in order of "id" ASC
$array_to_sort = array(
array("id" => "1", "name" => "text1", "help" => "helptxt2");
array("id" => "2", "name" => "text2", "help" => "helptxt2");
);

The SQL-Queries: SQL-Ouery for $sorting_array: (the db-field 'conf' is setup as "text", maybe this is my problem so that I have to first explode and implode the entries before I could use it for the next query.)

[Code]....

I could access $array_to_sort as follows to see the content one by one:
(if the lines below don't match the array above, than I mixed it up. However, the lines below is what brings the content)

[Code]....

But it is sorted by "id" ASC, but I need exactly the sorting as in $sorting_array. I tried some things with:

[Code]....

which only brings the Id's in the correct order, but not the content. Now I'm a bit confused, as I tried so many things, but all ended up in giving me the same results. Maybe the sql-query could be done in one step, but I didn't brought it to work. All results to my searches just showed how to sort ASC or DESC, but not what I want. Furthermore I must confess that I'm relative new to PHP and MySQL.

Loop Through A Section Of One Array To Create A 2D Associative Array?

Mar 26, 2010

The setup:  I've got a flat file (.txt) that I pull in to a template.php file.  The template.php turns the .txt's data into an array, and assigns each segment of the array a variable ( ie : $pagename = substr($data[17], 0 , -1); ).  Then it creates/displays the page based on those variables.

The problem is that the .txt files are all going to be different lengths, and they all end in a repeating list of "products" (this is for a gallery, of sorts).  Each "product" has twelve rows of data (so, twelve lines in the text file -- Product Name, Product Link, Product Image, Product Owner, etc), and what I need to do is grab that ending list and break it out into its own associative two-dimensional array (a parent array of a variable number of children associative arrays -- the "products" -- that each have a dozen chunks).

So, here's what I've got:

if ($type == "multi") {
$pagename = substr($data[17], 0 , -1);
$loopcount = substr($data[16], 0 , -1);
for ($counter = 0; $counter < $loopcount; $counter += 1) {
$proditerate = 18 + ($counter * 12);
