Is PHP Boolean case sensitive?

I know JavaScript is case sensitive but I am wondering about php. In the Booleans section the teacher used capital letters.Example

<?php
 $boolean = TRUE;
echo $boolean;

//  is  it the same as this below

$boolean = true;
 echo $boolean;
?>

Hey Abraham,

They are not case-sensitive, but the general consensus among PHP coders is to use all upper-case. It's more of a stylistic preference than an actual syntax rule.

In php you can use either TRUE or true same with FALSE and false.

Here is the PHP Manual on booleans: http://php.net/manual/en/language.types.boolean.php
