php - Else break deletes variable -

-

i going through series of values checking if same or different, want how many values @ top of list same.

$counter=0; while ($value<$numberofvalues){     if($valuea == $valueb){           $counter++;     }else{          break;     }  }   echo $counter;

why $counter equals 0 after break?

thanks in advance!

because value , numberofvalues should have $ in front of them ($value , $numberofvalues), otherwise while() loop not run @ , $counter still 0.
