从PHP脚本运行java

我尝试从PHP运行java，但我甚至无法使用java可执行文件的绝对路径（C：\ Windows \ System32 \ java.exe）。从PHP脚本运行java

我发现问题是PHP不能访问这个文件，出于某种原因。我尝试：

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

文件实际上存在，我（用户在谁我运行php脚本）有权限读取和执行它。这是非常奇怪的，因为我可以执行的notepad.exe和

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

任何想法？

作为一个建议：
从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：
结果的file_exists将被缓存。
也许你要调用clearstatcache()

编辑：
您可以尝试以下操作：

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

safe_mode在我的php.ini中被禁用 clearstatcache（）没有帮助 – NikitaObukhov 2014-09-10 09:30:40

我编辑了我的答案... – Ben 2014-09-10 09:37:58

遇到同样的问题，并从Windows/System32文件夹搬迁的java.exe 来解决问题例如C：/ Java （假设可执行文件C：/Java/java.exe现在实际存在）'file_exists（“C：/Java/java.exe”）'（和'is_executable（“C：/ Java/java。 exe“）'）现在应该返回true。
