It is possible to ignore some parts of code from a php file when it's analyzed by PHP_CodeSniffer
?
Yes it is possible with @codingStandardsIgnoreStart and @codingStandardsIgnoreEnd annotations
<?php
some_code();
// @codingStandardsIgnoreStart
this_will_be_ignored();
// @codingStandardsIgnoreEnd
some_other_code();
It is also described in the documentation.
