PHP Case Sensitivity

Hello World!
Hello World!
Hello World!

<?php
ECHO "Hello World!<br>";
echo "Hello World!<br>";
EcHo "Hello World!<br>";
?>

In PHP, keywords (e.g. if, else, while, echo, etc.), classes, functions, and user-defined functions are not case-sensitive. Note: However; all variable names are case-sensitive!
