Filter_var_array alternative

I was talking about filters which already have a native php function alternative. Considering the two alternatives below, are there any performance differences? Gets multiple variables and optionally filters them function. These options can be pretty useful alternatives to the validation filters covered in previous articles of the series. So using is_numeric() to test for numeric fields and is_alphabetic() to test for fields that can only contain letters is the best alternative for validating those field types.

Associative array of options or bitwise disjunction of flags. Get the index of the color of a pixelfunction-imagecolorclosest. The approach of this post works, but it will throw problems if you need to scale.

For now, it is important to know that there are alternative classes that wrap around the original classes and execute cross-cutting logic.
