Triple¶

Triple usually means that something appears only three times in a row.

Triple is opposed to double and single, but it may also be distinct with any other number of repetition, such as quadruple, etc.

Things that may be triple:

Triple equal ===, not to be confused with the single equal = or the double one ==.

<?php

    $a = 1;
    $a == 1;  // true
    $a === 1; // true too.

?>
