JumbledIncrementer #

Detects incrementer jumbling in for loops.

This rule is based on the PMD rule catalogue. The jumbling incrementer sniff detects the usage of one and the same incrementer into an outer and an inner loop. Even it is intended this is confusing code.

class Foo
{
    public function bar($x)
    {
        for ($i = 0; $i < 10; $i++)
        {
            for ($k = 0; $k < 20; $i++)
            {
                echo 'Hello';
            }
        }
    }
}
