two keys in arrays

[sarathi]

Is it possible to have more than one key point to the same value in an array? Somtheing like this:

 

$array = array('$key1, $key2' => '$value1');

I guess you could pass the first by reference;

 

<?php
$array['key1'] = ' value1';
$array['key2'] =& $array['key1'];

I'm not sure if it is possible when creating the array, unless you manually define them to have the same value, but then affecting one won't affect the other.

 

You could do it with a reference though:

<?php
$foo = array(1 => 'bar');
$foo[0] =& $foo[1];

echo "<pre>",print_r($foo),"</pre>";
?>

 

EDIT: Beaten to it.

Ok, I'll just set the second key to the first one, that will really shorten how much I have to write.

 

Thanks!
