What is the difference between the | and || operators?

Question

| and || - what is the difference between these two operators in PHP?

Answer 1

| -> binary operator || -> Boolean operator or -> also a Boolean operator with lower precedence

$x = false | true; //will set $x to an integer
$x = false || true; //will set $x to true
$x = false or true; //will set $x to false exactly the same that:
($x = false) || true;
