Parse a query string into an array

Question

I have a string that looks like:

single=Single&multiple=Multiple2&check=check1&radio=radio2

how could I create a array like this:

array(
 'single' => 'Single',
 'multiple' => 'Multiple2',
 'check' => 'check1',
 'radio' => 'radio2',
)

Answer 1

Use parse_str

parse_str('single=Single&multiple=Multiple2&check=check1&radio=radio2', $data);

And in $data you will have your variables.

• nv1t: Keep in Mind: without using $data you will create a security issue, coz you are loading data into your current scope, so it is crucial to use it :)

Answer 2

If this comes from an URL you can have this already as an array in the $_GET or $_POST variables. Otherwise use explode() to convert string to an array.

• Alex: it comes from a hidden form field generated with jquery, like this: api.jquery.com/serialize
• Elzo Valugi: if you are using ajax(), get() or post() to send it to php you still should have it in the global vars. As an extra suggestion, filter_var the vars that come from js, before using them.
• Alex: yes, I do, but only the hidden input (it's all I need). all the other inputs are there just to build this string :)
• Elzo Valugi: it does not matter, those jquery functions send them as POST or GET parameters depending on your request.
