Question

In my last project I had to specify a value, normally I use the following statement:

<?php 
  $true = 1;
  $false = 0;
  $hasAccess = $true ? 1 : 0;
  print $hasAccess;
?>

but this works to:

<?php 
  $true = 1;
  $false = 0;
  $hasAccess = $true || $false;
  print $hasAccess;
?>

Why?

Update: I know what a OR / || is and what I have to expect from it. But I haven’t seen this possibility any time before.

Answer 1

Because 0 is automaticly casted to (bool)false, and anything else (bool)true.
So what you are basicly saying is:

$hasaccess = true OR false;
