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; ?>

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

Answer 1

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

• Barmar: A more idiomatic way to write it is $uphPerOperator[] = $i;
• dWinder: When answering you own answer you can mark it as accepted. I think you should also add link to the official documentation of tge array_push function
