Warning 在PHP里屬于比較輕的錯誤提示，通常不會嚴重影響程序的正常運行。
Warning: chdir() 這個警告提示No error，那么可能是對于chdir() 這個函數，服務器端權限安全設置導致的。
Warning: Cannot modify header information
這種警告在PHP里比較常見，原因也有多樣，解決辦法：
1. 檢查有<?php ... ?> 前面沒有空白行，特別是include或者require的文件。不少問題是這些空白行導致的。
2. 在header后加上exit();
header ("Location: xxx");exit(); |
3. 用Javascrīpt來解決:
<? echo "<scrīpt> self.location( file.php );</scrīpt>"; ?> |
4. 用輸出緩存來解決:
<?php ob_start(); ?>... HTML codes ...<?php... PHP codes ...header ("Location: ....");ob_end_flush();?> |
5. 開啟php.ini中的
output_buffering = On |
