用PHP上传文件时,我们会用程序去监听浏览器发送过来的文件信息,首先会通 过$_FILES[fieldName][‘error‘]的不同数值来判断此欲上传的文件状态是否正常。$_FILES[fieldName] [‘error‘]==0代表一切正常,其它数值的具体含义请参考下面一段程序的注释部分,如有翻译不到之处还望指正!
switch($_FILES[$field][‘error‘]) {
case 1:
// 文件大小超出了服务器的空间大小
$this->setError("The file is too large (server).");
break;
case 2:
// 要上传的文件大小超出浏览器限制
$this->setError("The file is too large (form).");
break;
case 3:
// 文件仅部分被上传
$this->setError("The file was only partially uploaded.");
break;
case 4:
// 没有找到要上传的文件
$this->setError("No file was uploaded.");
break;
case 5:
// 服务器临时文件夹丢失
$this->setError("The servers temporary folder is missing.");
break;
case 6:
// 文件写入到临时文件夹出错
$this->setError("Failed to write to the temporary folder.");
break;
}
