dynamic arrays in php

[backpacklondon.com]

Hello,


I'm attempting to populate my associative arrays dynamically, does anyone know if this is possible please?

e.g. I'd like the associative array

delimeter["dynamically_created"][1] = stuff;


but, writing:

$dynamically_created = "stuff";
$delimiter[$dynamically_created][1] = "stuff";

doesn't seem to do it?

Do you know how to do this please?

I've noticed it's poss. to create them dynamically if I use integers, but I'd like to use strings.

Cheers,

Jason

I don't understand: don't you have to use integers to number the arrays? I do recall something about arrays with text values instead of integers...am I imagining that?

I'll go look this up in my big old red PHP book and see if I can figure it out.

Alright, I don't see the problem.

Checkout these two blocks of code:

<?php
$dynamically_created = "stuff";
$delimiter[$dynamically_created][1] = "stuff";
echo($delimiter[$dynamically_created][1]);
?>

Now this one...

<?php
$dynamically_created = "stuff";
$delimiter[$dynamically_created][1] = "stuff";
echo($delimiter["stuff"][1]);
?>

Both of those print the word "stuff" onto the page. Could you elaborate on your problem a bit, because I don't see any problem. I may be misunderstanding you, however.

You're not misunderstanding!


Sorry mate, the problem was fatigue I think....!!!

Commish,
arrays can be indexed using numbers, text or a combo.

When text is used they are called associative arrays.
It is not uncommon to have soemthing like this.

$links[1][title]="A LINK";
$links[1][desc]="This is a link!..";
$links[2][title]="A LINK2";
$links[2][desc]="This is a link descritpion for link2!..";
foreach($links as $link){
echo '<B>'.$link[title].'</b><BR>';
echo '<font size=1>'.$link[desc];
}

Messy code (its time for bed!) but you get the idea...

Also you could have the following

$array[1][1][1][2][4]="hi";

if you really were so inclined...i dont think there is any limit in PHP...not to sure on that though, and i will leave it to freddy to delve deep into the langaueg and enlighten us regards how many keys an array value can have...from me its goodnight i will see you in 12 hours!.

Oh yes, multi-dimensional arrays, right? Sort of like a mini-database if you just want to store a little bit of data.

And no problem Jase: I know what you mean. Glad to have helped!

The only thing I have to add is that you can specify the key for an array anyway you like.

Whether you do it

$dynamically_created = "stuff";
$delimiter[$dynamically_created][1] = "stuff";

$delimiter["stuff"][1] = "stuff";

$delimiter = array("stuff" => array(1 => "stuff"));

printing $delimiter["stuff"][1] will

print

stuff

inall cases
