=====================
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.
