php - 检测到错误时重新启动 while 循环的当前操作

Question

我在下面有一个 PHP 循环，它可以正常工作，但是有时 CURL 请求会返回一个错误页面，我怎样才能只重新启动当前页面的操作而不重新启动整个循环？

while ($daytofetch <= $lastdaytofetch) {

//Do all my stuff and run curl request here 

$daytofetch++

}

Answer 1

我可能会做这样的事情：

while ($daytofetch <= $lastdaytofetch) {
    $error = false;


    //Do all my stuff and run curl request here
    //if there is an error, then set $error = true;


    if (!$error)
        $daytofetch++
}

Answer 2

while ($daytofetch <= $lastdaytofetch) {

    // Do all my stuff and run curl request here

    if ($error_detected) {
        // This will resume the loop without incrementing
        // $daystofetch
        continue;
    }

    $daytofetch++
}
