PHP $_FILES中error返回值詳解

$_FILES['file']['error']值

UPLOAD_ERR_OK: 0 //正常，上傳成功

UPLOAD_ERR_INI_SIZE: 1 //上傳文件大小超過服務器允許上傳的最大值，php.ini中設置upload_max_filesize選項限制的值

UPLOAD_ERR_FORM_SIZE: 2 //上傳文件大小超過HTML表單中隱藏域MAX_FILE_SIZE選項指定的值

UPLOAD_ERR_NO_TMP_DIR: 6 //沒有找不到臨時文件夾

UPLOAD_ERR_CANT_WRITE: 7 //文件寫入失敗

UPLOAD_ERR_EXTENSION: 8 //php文件上傳擴展沒有打開

UPLOAD_ERR_PARTIAL: 3 //文件只有部分被上傳

復制代碼 代碼如下:
switch($_FILES[$field]['error']) {  

    case 1:   
        // 文件大小超出了服務器的空間大小   
        $this->setError("The file is too large (server).");   
break;   

case 2:   
        // 要上傳的文件大小超出浏覽器限制   
        $this->setError("The file is too large (form).");   
        break;   

    case 3:   
        // 文件僅部分被上傳   
        $this->setError("The file was only partially uploaded.");   
        break;   

    case 4:   
        // 沒有找到要上傳的文件   
        $this->setError("No file was uploaded.");   
        break;   

    case 5:   
        // 服務器臨時文件夾丟失   
        $this->setError("The servers temporary folder is missing.");   
        break;   

    case 6:   
        // 文件寫入到臨時文件夾出錯   
        $this->setError("Failed to write to the temporary folder.");   
        break;   
}
