Fastest method to parse URL parameters into variables in PHP [duplicate]

Question

Possible Duplicate:
Parse query string into an array

What's the fastest method, to parse a string of URL parameters into an array of accessible variables?

$current_param = 'name=Peter&car=Volvo&pizza=Diavola&....';

// Results in a nice array that I can pass:

$result = array (
    'name'  => 'Peter',
    'car'   => 'Volvo',
    'pizza' => 'Diavola'
)

I've tested a regular expression, but this takes way too long. My script needs to parse about 10000+ URLs at once sometimes :-(

KISS - keep it simple, stupid

The fastest method is to use parse_str. Regular expressions are way too expensive and the algorithm to parse a URL is very simple. That's the fastest way on one machine. If you require performance, you can always split the work across many machines but that's both more expensive and tiny bit harder to implement, especially with PHP. — N.B.

Use parse_str().

$current_param = "name=Peter&car=Volvo&pizza=Diavola";
parse_str($current_param, $result);
print_r($result);

The above will output

Array
(
    [name] => Peter
    [car] => Volvo
    [pizza] => Diavola
)

The parse_str() function can do the trick as you expect:

<?php
    $str = "first=value&arr[]=foo+bar&arr[]=baz";
    parse_str($str);
    echo $first;  // value
    echo $arr[0]; // foo bar
    echo $arr[1]; // baz

    parse_str($str, $output);
    echo $output['first'];  // value
    echo $output['arr'][0]; // foo bar
    echo $output['arr'][1]; // baz
?>
