I'm, not entirely sure, but I think foreach may grab a copy of the keys
before iteration. I've never worried about that in foreach although I
can remember issues back in the old days with the reset(), next(), end()
set of array traversal functions :)
If you're at all worried anyways, you can always do:
?php
foreach( array_keys( $_POST ) as $key )
{
if( strpos( $key, '_' ) !== false )
{
$_POST[str_replace( '_', '', $key )] = $_POST[$key];
}
}
?

[PHP] Alter an Array Key
Hello, Is there any easy way to alter a key's name? I would like to remove some underscores in the $_POST array keys. Thanks, OD -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

?php
foreach( $_POST as $key = $value )
{
if( strpos( $key, '_' ) !== false )
{
$_POST[str_replace( '_', '', $key )] = $value;
unset( $_POST[$key] );
}
}
?
I would suggest NOT removing the original key though and just have both.
To do so just comment out/remove the line that has unset().
Cheers,
Rob.

But, that probably doesn't answer your question. Why don't you supply us with an example of how you are using the $_POST array and maybe we can give you a better solution. -- Jim Lucas Some men are born to greatness, some achieve greatness, and some have greatness thrust upon them.

Not directly, but:
$post = array();
foreach($_POST as $k = $v){
$k = str_replace('_', ' ', $k);
$post[$k] = $v;
}
You could dink with unset instead, but it's a Bad Idea to alter what
is actually in $_POST, imho.
And you also don't really want to add new elements to an array while
you iterate through it, generally... Though I think maybe foreach
does the right thing with that.
Better to build a new array and put the stuff you want into that.
