How can I turn a string below into an array?

pg_id=2&parent_id=2&document&video

This is the array I am looking for,

array(
'pg_id' => 2,
'parent_id' => 2,
'document' => ,
'video' =>
)

You want the parse_str function, and you need to set the second parameter to have the data put in an array instead of into individual variables.

 $get_string = "pg_id=2&parent_id=2&document&video";

 parse_str($get_string, $get_array);

 print_r($get_array);

Using parse_str().

$str = 'pg_id=2&parent_id=2&document&video';
parse_str($str, $arr);
print_r($arr);

There are several possible methods, but for you, there is already a builtin function

$array = array();
parse_str($string, $array);
var_dump($array);

Use http://us1.php.net/parse_str

Attention, it's:

parse_str($str, &$array)

not

$array = parse_str($str);.

You can simply use http_build_query (Documentation)

<?php

$data = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&amp;');

?>

This answers the opposite question. He wants to turn a query string into an array, not the other way around. –  Mark Amery Jan 29 at 16:19
