Apache错误与一个PHP文件，而不是另一个相同的

我在一个特定的文件上遇到了一些服务器500错误的问题，这个文件在本地工作得很好，直到我把它上传到主机。

因此将文件简化为php得到的那么简单。代码是:

 <?php
  echo "hello,hello";
 ?>

当它被称为test4.php时，它给出了500错误。然后当我将它重命名为test5.php它工作，test6.php失败

两个相同文件的转储-一个有效，一个无效:

 [~/www/]# hexdump test5.php
0000000 3f3c 6870 0a70 6365 6f68 2220 6568 6c6c
0000010 2c6f 6568 6c6c 226f 0a3b 3e3f 000a     
000001d
 [~/www/]# hexdump test4.php
0000000 3f3c 6870 0a70 6365 6f68 2220 6568 6c6c
0000010 2c6f 6568 6c6c 226f 0a3b 3e3f 000a     
000001d

test7.php作品

test11.php失败

testtest.php失败

cp test5.php

cp dent.php

cp test11.php testtest.php -工作-以前没有

cp test7.php to vest7.php

enter code here

关于这里可能发生的事情有什么线索吗?下面是一些其他细节。非常感谢凯文
