PHP array counting

Question

I have the following php code where it goes through a loop and push elements to an array. I wanted to count elements in that array at the end of the loop. But it is not showing anything. Can someone please help me here?

<?php
  $i=0;
  $uphPerOperator = [];
    while($i<10){
     $uphPerOperator = array_push($uphPerOperator,$i);
     $i++;
    }
  $uphArrayCount = count($uphPerOperator);   
  echo $uphArrayCount; ?>

You use array_push the wrong way, see the php manual to see how this function works and what it is supposed to return. — Casimir et Hippolyte

I got the code working by changing it following way

<?php
  $i=0;
  $uphPerOperator = [];
    while($i<10){
     array_push($uphPerOperator,$i);
     $i++;
    }
  $uphArrayCount = count($uphPerOperator);   
  echo $uphArrayCount; ?>

Basically I changed $uphPerOperator = array_push($uphPerOperator,$i); to array_push($uphPerOperator,$i); and it works

A more idiomatic way to write it is $uphPerOperator[] = $i;
