爲什麼文件上傳的錯誤代碼？

Question

我寫PHP文件上傳自定義錯誤處理/報告功能，我注意到，返回的錯誤代碼是從0到8，除了5

這是在源錯字我使用的還是真的這樣嗎？如果是這樣，我很好奇他們爲什麼跳過數字'5'。

謝謝。

編輯 迴應Pekka，這裏是PHP手冊的錯誤代碼。

 
0 | UPLOAD_ERR_OK   | There is no error, the file uploaded with success. 
1 | UPLOAD_ERR_INI_SIZE | Size exceeds upload_max_filesize in php.ini. 
2 | UPLOAD_ERR_FORM_SIZE | Size exceeds MAX_FILE_SIZE specified in HTML form. 
3 | UPLOAD_ERR_PARTIAL | The uploaded file was only partially uploaded. 
4 | UPLOAD_ERR_NO_FILE | No file was uploaded. 
5 | UPLOAD_ERROR_E  | As explained by @Progman, removed in rev. 81792 
6 | UPLOAD_ERR_NO_TMP_DIR | Missing a temporary folder. 
7 | UPLOAD_ERR_CANT_WRITE | Failed to write file to disk. 
8 | UPLOAD_ERR_EXTENSION | File upload stopped by extension.

無論如何，無論如何您都使用UPLOAD_ERR_*常量並不重要。但我想現場5是一個錯誤，現在由不同的錯誤情況處理。

的情況下， 「5」 是空的上傳文件的錯誤。但是，這不是一個錯誤，所以字段/常量被刪除。見changeset 81792 on main/rfc1867.c和changeset 88408 on main/rfc1867.c
