How to check for a variable with a certain value?

I want an if statement that not only checks for the existence of a variable, but which also checks all the variables already created for one with a specific value. For example, I have a loop which creates variables, but I don't want it to make two variables with the same value. The problem is, using

if(isset(${'h'.$x}==false) && ${'h'.$x} != 3{



}

won't work since the variable equal to 3 could be named h4, whereas this one will be named h5. I hoped I explained this efficiently enough, sorry about any confusion.

$count = count($bytes);
	for($x=0; $x<$count; $x++){
		${'h' . $x} = substr($bytes[$x],8,-;
		$array1[${'h' . $x}] = array();
		$array2[${'h' . $x}] = array();
		$array3[${'h' . $x}] = array();
		$array4[${'h' . $x}] = array();
		$array5[${'h' . $x}] = array();
		$offset[${'h' . $x}] = array();
		$avg[${'h' . $x}] = array();
		$avg2[${'h' . $x}] = array();
		$percentage[${'h' . $x}] = array();
		$values[${'h' . $x}] = null;
		
		}
		

This is my code, where $bytes is an array containing the preg_match_all. The thing is, sometimes there is the same matchable string twice, meaning that it will create the same array key 2 times. Also, there will be two different variables, such as h2 and h13, which will have the same value. That doesn't screw the program up at all, but it makes a hell of a lot of error messages pop up. I just want to make sure that there are no $hx variables with the same value.

 

P.S. I apologize if my code looks like crap. I'm still learning.
