從PHP腳本運行java

我嘗試從PHP運行java，但我甚至無法使用java可執行文件的絕對路徑（C：\ Windows \ System32 \ java.exe）。從PHP腳本運行java

我發現問題是PHP不能訪問這個文件，出於某種原因。我嘗試：

<?php var_dump(file_exists('C:\Windows\System32\java.exe')); // returns false.

文件實際上存在，我（用戶在誰我運行php腳本）有權限讀取和執行它。這是非常奇怪的，因爲我可以執行的notepad.exe和

<?php var_dump(file_exists('C:\Windows\System32\notepad.exe')); // returns true.

任何想法？

，如果你想用你的PHP運行Java使用php-jaja-bridge.see here：http://php-java-bridge.sourceforge.net/pjb/

作爲一個建議：
從PHP.net到file_exists：

This function returns FALSE for files inaccessible due to safe mode restrictions. However these files still can be included if they are located in safe_mode_include_dir.

另外：
結果的file_exists將被緩存。
也許你要調用clearstatcache()

編輯：
您可以嘗試以下操作：

<?php var_dump(file_exists("C:\\Windows\\System32\\java.exe"));

safe_mode在我的php.ini中被禁用 clearstatcache（）沒有幫助 – NikitaObukhov 2014-09-10 09:30:40

我編輯了我的答案... – Ben 2014-09-10 09:37:58

遇到同樣的問題，並從Windows/System32文件夾搬遷的java.exe 來解決問題例如C：/ Java （假設可執行文件C：/Java/java.exe現在實際存在）'file_exists（「C：/Java/java.exe」）'（和'is_executable（「C：/ Java/java。 exe「）'）現在應該返回true。
