http_build_query()
The http_build_query() native function is used to generate a URL-encoded query string from an associative array or an object. This is commonly used to build query strings for HTTP GET requests or for use in URLs.
http_build_query() converts automatically backed enumerations to their type value, integer or string, when they are used as values in the array. This is a PHP 8.4 feature.
http_build_query() provides arguments to deal with numeric keys, a prefix may be added, with custom separators and encoding type.
The reverse function for http_build_query() is parse_str(), which converts a query string into an array.
<?php
enum A: int {
case A = 1;
}
print http_build_query(['x' => A::A, 'b' => 3]);
// x=1&b=3
?>
