Question

I try to remove a prefix in array keys and every attempt is failing. What I want to achieve is to:

Having: Array ( [attr_Size] => 3 [attr_Colour] => 7 )

To Get: Array ( [Size] => 3 [Colour] => 7 )

Your help will be much appreciated…

Answer 1

One of the ways To Get:Array ( [Size] => 3 [Colour] => 7 ) From your Having: Array ( [attr_Size] => 3 [attr_Colour] => 7 )

$new_arr = array();
foreach($Your_arr as $key => $value) {

list($dummy, $newkey) = explode('_', $key);
$new_arr[$newkey] = $value;

}

If you think there’ll be multiple underscores in keys just replace first line inside foreach with list($dummy, $newkey) = explode('attr_', $key);
