What is the best way to implement an "else" condition for a while loop in PHP?

When using a while loop in PHP, there is no built-in "else" condition like in an if statement. To implement an "else" condition for a while loop, you can introduce a boolean variable that tracks whether the loop was executed at least once. Then, after the while loop, you can check this variable to determine if the loop was never executed.

$condition = true;
while ($condition) {
    // loop body
    $condition = false; // update the condition to exit the loop
}

if ($condition) {
    // code to execute if the loop never ran
}
