Question

Say you have an array built using wp_parse_args(). Is there a built in method in WordPress to create a url using said array, or would I have to resort to a custom function?

Answer 1

PHP has a function bulit-in to convert arrays to query strings: http_build_query

Here’s an example:

$arr = array('name' => 'Eric', 'age' => 23, 'sex' => 'M');
$query = http_build_query($arr); // 'name=Eric&age=23&sex=M'
$url = 'http://example.com/?'.$query;
