Rule strict_param

Functions should be used with $strict param set to true.


The functions “array_keys”, “array_search”, “base64_decode”, “in_array” and “mb_detect_encoding” should be used with $strict param.


Using this rule is risky

Risky when the fixed function is overridden or if the code relies on non-strict usage.


Example #1

+++ New
 $a = array_keys($b);
-$a = array_search($b, $c);
-$a = base64_decode($b);
-$a = in_array($b, $c);
-$a = mb_detect_encoding($b, $c);
+$a = array_search($b, $c, true);
+$a = base64_decode($b, true);
+$a = in_array($b, $c, true);
+$a = mb_detect_encoding($b, $c, true);
