assigning array key name by variable

[spaghettio05]

Hi all,

 

I can't seem to designate an array key by using a variable and I was wondering if this is possible. I'm looking to do something like this:

 

 
<?php
$key = "apple";
$arr = array($key => "fruit");
?>

 

Any suggestions would be appreciated!

To answer your question: variable variables

<?php
$key = "apple";
$arr = array($$key => "fruit");
?>

 

Although, I prefer keys and values like:

<?php
$arr = array('fruit' => 'apple');


echo 'Hmmm, what kind of fruit do we have?  Oh an, ' . $arr['fruit'] . '!';
?>

To answer your question: variable variables

<?php
$key = "apple";
$arr = array($$key => "fruit");
?>

This will throw an undefined variable error.

The OP's original code was correct, I suspect the issue is in the retrieval.

$key = "apple";
$arr = array($key => "fruit");
print_r($arr);
// Output: Array ( [apple] => fruit )

Oops, yes, my original code is correct (found the mistake in my other code from which it came). Thanks for the replies!

Yes, buddski, you are correct.  Didn't think that one through.
