When using codesniffer to check your code, a lot of warnings might appear when the lines are too long:
----------------------------------------------------------------------
FOUND 0 ERRORS AND 4 WARNINGS AFFECTING 4 LINES
----------------------------------------------------------------------
73 | WARNING | Line exceeds 120 characters; contains 162 characters
75 | WARNING | Line exceeds 120 characters; contains 124 characters
102 | WARNING | Line exceeds 120 characters; contains 168 characters
108 | WARNING | Line exceeds 120 characters; contains 121 characters
----------------------------------------------------------------------
To ignore those warnings, we can add // phpcs:ignore as a comment to the end of a (too long) line. For example:
<?php
$message = 'This is my long message. It\'s not only long, it\'s extreeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeemly long'; // phpcs:ignore
