Question

I’m looking for a fast way to turn an associative array in to a string. Typical structure would be like a URL query string but with customizable separators so I can use ‘&‘ for xhtml links or ‘&‘ otherwise.

My first inclination is to use foreach but since my method could be called many times in one request I fear it might be too slow.

<?php $Amp = $IsXhtml ? '&amp;' : '&'; $Parameters = array('Action' => 'ShowList', 'Page' => '2'); $QueryString = ''; foreach ($Parameters as $Key => $Value)         $QueryString .= $Amp . $Key . '=' . $Value; 

Is there a faster way?

Answer 1

You can use http_build_query() to do that.

Generates a URL-encoded query string from the associative (or indexed) array provided.
