Rule strict_param

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

Description

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

Warning

Using this rule is risky

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