PHP function to build query string from array

Question

Hi,

I'm looking for the name of the PHP function to build a query string from an array of key value pairs. Please note, I am looking for the built in PHP function to do this, not a homebrew one (thats all a google search seems to return). There is one I just can't remeber it's name or find it on php.net. IIRC it's name isn't that intuitive.

Answer 1

I'm not aware of a builtin function, but there is the PECL class http://uk.php.net/manual/en/class.httpquerystring.php

Answer 2

Implode will combine an array into a string for you, but to make an SQL query out a kay/value pair you'll have to write your own function.

Answer 3

Your looking for http_build_query().
