What is the significance of the double-pipe (||) symbol in PHP code?

The double-pipe (||) symbol in PHP is used as the logical OR operator. It is used to combine two conditions and returns true if either of the conditions is true. This can be useful when you want to check multiple conditions in an if statement and take action if any of them are met. Example:

// Check if either $x or $y is greater than 10
if ($x > 10 || $y > 10) {
    echo "Either $x or $y is greater than 10";
}
