http_build_query with same name parameters

Question

Is there a way to build a query automatically with http_build_query using parameters with the same name?

If I do something like

array('foo' => 'x', 'foo' => 'y'); 

They are obviously overwritten within the array, but even if I do:

array('foo' => array('x', 'y')); 

The function creates something like foo[0]=x&foo[1], which isn't what I want, since I need the parameters in this format foo=x&foo=y.

This should do what you want, I had an api that required the same thing.

$vars = array('foo' => array('x','y')); $query = http_build_query($vars, null, '&'); $string = preg_replace('/%5B(?:[0-9]|[1-9][0-9]+)%5D=/', '=', $query); //foo=x&foo=y
