Since PHP 4.2.0, PHP returns an appropriate error code along with the
file array. The error code can be found in the
['error'] segment of the file array that is created
during the file upload by PHP. In other words, the error might be
found in $_FILES['userfile']['error'].
- UPLOAD_ERR_OK
Value: 0; There is no error, the file uploaded with success.
- UPLOAD_ERR_INI_SIZE
Value: 1; The uploaded file exceeds the
upload_max_filesize
directive in php.ini.
- UPLOAD_ERR_FORM_SIZE
Value: 2; The uploaded file exceeds the MAX_FILE_SIZE
directive that was specified in the HTML form.
- UPLOAD_ERR_PARTIAL
Value: 3; The uploaded file was only partially uploaded.
- UPLOAD_ERR_NO_FILE
Value: 4; No file was uploaded.
Note:
These became PHP constants in PHP 4.3.0.
