<?php
// not so great:
if ($blah) {
    $doSomething;
} else {
    throw Exception();
}

// better:
// be explict
// no need to overcomplicate with else
if (false === $blah) {
    throw Exception();
}
$doSomething;


// Also good in methods:

function foo()
{
    if ($somethingDidntWork) {
        return; // this exits from the method, no need to "else"
    }
    $doSomething;
    andMore();
    return 'whatever';
}
