遇到一個奇怪的問題，明明 PHP 有收到檔案，
$_SERVER['CONTENT_LENGTH'] 不是空的，但 $_FILES 陣列卻是空的，
而 upload tmp dir 裡也沒有檔案。
以下是我的測試，沒發現問題在哪，不知道各位有沒有什麼建議？
測試用的 upload_test.php
<?php
if ( 'POST' === $_SERVER['REQUEST_METHOD'] ) {
echo 'var_dump($_SERVER[\'CONTENT_LENGTH\']) : ';
var_dump($_SERVER['CONTENT_LENGTH']);
echo 'var_dump($_FILES) : ';
var_dump($_FILES);
} else {
echo 'there\'s no file uploaded'."\n";
}
?>
測試沒有檔案上傳:
root@m:/var/www# curl localhost/upload_test.php
there's no file uploaded
測試上傳：
傳了一個 1.1K 的文字擋上去，有傳到 PHP，但 $_FILES 陣列印出來卻是空的:
root@m:/var/www# curl localhost/upload_test.php -F file=@test.txt
var_dump($_SERVER['CONTENT_LENGTH']) : string(4) "1287"
var_dump($_FILES) : array(0) {}
檢查 apache/php.ini 相關的設定，檔案沒有超出上傳限制
safe_mode Off Off
file_uploads On On
max_execution_time 3000 3000
max_file_uploads no value no value
max_input_nesting_level 64 64

max_input_vars 1000 1000
post_max_size 128M 128M
upload_max_filesize 128M 128M
upload_tmp_dir /var/tmp/php /var/tmp/php

suhosin.upload.disallow_elf 1 1
suhosin.upload.max_uploads 25 25
suhosin.upload.remove_binary 0 0
suhosin.upload.verification_script no value no value
檢查 upload_tmp_dir 資料夾權限，全開通行無阻
root@m:/etc/php5# ll -d /var/tmp/php
