1.2.23. All Uppercase Variables¶
Usually, global variables are all in uppercase, so as to differentiate them easily. Though, this is not always the case, with examples like $argc, $argv or $http_response_header.
When using custom variables, try to use lowercase $variables, $camelCase, $sturdyCase or $snake_case.
<?php
// PHP super global, also identified by the initial _
$localVariable = $_POST;
// PHP globals
$localVariable = $GLOBALS['HTTPS'];
?>
