Zend Studio reports warning: Assignment in condition. Is this so bad?

Question

I have recently started using Zend Studio which has reported as warning the following type of code:

$q = query(\"select * from some_table where some_conditio         


        

Answer 1

Actually, I guess your question has already been answered, somewhat. But to address your actual problem, I think this might help.

//i dont know what is returned if there are no more records to fetch...
//but lets assume it is a boolean value
while (($f = fetch($q))!= false)
{
    $this->doSomethingVeryImportantThatMakesYourBossHappy($f);
}

That should do the trick and the "Assignment in condition"-message should disappear.

As a sidenote: use the equals operator the same way as when you negate stuff. You also use the equals sign with other operators like

if ($falseness != false){$trueness = true}

and not

if ($falseness ! false){$trueness = false}

That helps me to always remember how to compare values and not assign values to them.
