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];
}
}
?>
Cheers,
Rob.
