How to Parse Query Strings into Arrays in PHP?

Parsing Query Strings into Arrays

Converting a query string into an array is a common task in web development. This allows you to easily access the individual parameters and their values.

Given a query string like the one below:

pg_id=2&parent_id=2&document&video

You can use the parse_str function to transform it into an array:

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

parse_str($queryString, $queryArray);

By setting the second parameter of parse_str to an empty array, you instruct it to store the parsed data in the specified variable rather than overwriting existing variables.

The resulting array, $queryArray, will have the following structure:

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

This array can now be used to conveniently access and manipulate the query string parameters.
