[PHP] control structure question

[Javier Montserat]

is there a more programmatically elegant way of saying...

$isError = "";

function main() {

    doStep1();

    if (!$isError) {
        doStep2();
    }

    if (!$isError) {
        doStep3();
    }
    // etc. etc.
}

function doStep1() {
    if ($something) {
        $isError = 1;
    }
}

function doStep2() {
    if ($something) {
        $isError = 1;
    }
}
