Any way to break if statement in PHP?

Question

Is there any command in PHP to stop executing the current or parent if statement, same as break or break(1) for switch/

Answer 1

Because you can break out of a do/while loop, let us "do" one round. With a while(false) at the end, the condition is never true and will not repeat, again.

do
{
    $subjectText = trim(filter_input(INPUT_POST, 'subject'));
    if(!$subjectText)
    {
        $smallInfo = 'Please give a subject.';
        break;
    }

    $messageText = trim(filter_input(INPUT_POST, 'message'));
    if(!$messageText)
    {
        $smallInfo = 'Please supply a message.';
        break;
    }
} while(false);
