用PHP上傳文件時窥突，我們會用程序去監(jiān)聽瀏覽器發(fā)送過來的文件信息惶室，首先會通 過$_FILES[fieldName]['error']的不同數(shù)值來判斷此欲上傳的文件狀態(tài)是否正常当娱。$_FILES[fieldName] ['error']==0代表一切正常卖局，其它數(shù)值的具體含義請參考下面一段程序的注釋部分，如有翻譯不到之處還望指正
$_FILES['file']['error']值
- UPLOAD_ERR_OK: 0 //正常渺杉，上傳成功
- UPLOAD_ERR_INI_SIZE: 1 //上傳文件大小超過服務器允許上傳的最大值蛇数，php.ini中設置upload_max_filesize選項限制的值
- UPLOAD_ERR_FORM_SIZE: 2 //上傳文件大小超過HTML表單中隱藏域MAX_FILE_SIZE選項指定的值
- UPLOAD_ERR_NO_TMP_DIR: 6 //沒有找不到臨時文件夾
- UPLOAD_ERR_CANT_WRITE: 7 //文件寫入失敗
- UPLOAD_ERR_EXTENSION: 8 //php文件上傳擴展沒有打開
- UPLOAD_ERR_PARTIAL: 3 //文件只有部分被上傳
switch($_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瀏覽器限制 $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;
}
