Limit to increment and decrement operators.
Allowed types: bool
Default value: false
Examples¶
Example #1¶
Default configuration.

+$sample = ~$c;
+function &foo(){}
Example #2¶
With configuration: ['only_dec_inc' => false].
--- Original
+++ New
<?php
-function foo($a, ... $b) { return (-- $a) * ($b ++);}
+function foo($a, ...$b) { return (--$a) * ($b++);}
Example #3¶
