Increment/Decrement Operators can increase costs

This code insight searches all the artifacts having increment/decrement operators.

Increment and decrement operators

1) cannot be used in an arithmetic operation.

Ex of violation :
$id = –$i – $x;

2) must be bracketed when used in string concatenation.

Ex of violation :
$id = $id.’_’.$i++;   
should be $id = $id.’_’.($i++);

3) should be used where possible.

Ex of violation :
$var = (1 – $var);
should be $var–;


Why you should care

For performance reasons, it is preferable to avoid incrementer/decrement operators.
This could be time and memory consuming.  Try to reduce the number of artifacts having Increment/decrement operators.

Business Impacts

It is recommended to avoid these in order to ensure the code is more readable and cost effective.
