How to Parse a Query String into an Array in PHP?

Parse Query String into an Array

When attempting to convert a string into an array, it's essential to understand the process and utilize the appropriate functions. In this particular case, the challenge is to transform a query string into an array format.

To achieve this, PHP offers the parse_str function. This function accepts a query string as its first parameter, and it converts the string into an array. However, by default, parse_str assigns the parsed data to individual variables. To store the data in an array instead, an additional second parameter must be added. This parameter should be an empty array, as seen below:

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

parse_str($queryString, $queryArray);

print_r($queryArray);

This code will transform the query string into an array called $queryArray, with each pair of key-value data from the query string stored as an element in the array. The output of print_r($queryArray) will be:

Array
(
    [pg_id] => 2
    [parent_id] => 2
    [document] => 
    [video] => 
)
