Converting a PHP Array to a Query String

We often need to convert a PHP array to a query string for use in a URL or POST request, and vice versa. Really, PHP is very rich with its build in functions as it has very useful function http_build_query() to convert a PHP array to a query string. Here in this post, I have an example to convert a PHP array to query string.

Generate a URL query string from a PHP array
First, let us take a look at the following PHP array:

<?php
$myarray= array(
'apikey'=>‘xg6tr7k’,
'user'=>'abcd',
'email'=>'jhon.php@example.com'
);
?>

Now let’s take a look at how we can convert above array to a query string using our PHP function http_build_query():

<?php
echo http_build_query($myarray);
?>

OUTPUT:

apikey=xg6tr7k&user=abcd&email=jhon.php%40example.com
