當檢測到錯誤時，重新啓動while循環的當前操作

Question

我有一個PHP循環，其下工作正常，但有時會有一個錯誤頁面由CURL請求返回，我如何才能重新啓動當前頁面的操作而不重新啓動整個循環？

while ($daytofetch <= $lastdaytofetch) { 

//Do all my stuff and run curl request here 

$daytofetch++ 

} 

Answer 1

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++ 
} 

Answer 2

我可能會做這樣的事情：

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++ 
}
