在使用file_get_contents时,出现奇怪的问题。

如果使用如下代码,可以运行:

<code>$ff =  "c:\\mywww\\www.bin3d.cn\\temp_upload\\files\\xxxx.txt";
echo file_get_contents($ff);
</code>
Copy after login
Copy after login

但是,如果是下面的代码就出现错误信息:

<code>$file = "xxxx.txt";
$ff =  "c:\\mywww\\www.bin3d.cn\\temp_upload\\files\\".$file."";
echo file_get_contents($ff);
</code>
Copy after login
Copy after login

错误信息是:

<code>Warning:  
file_get_contents(c:\mywww\www.xxx.cn\temp_upload\files\xxxx.txt): 
failed to open stream: No such file or directory in.... 
</code>
Copy after login
Copy after login

请问是什么问题呢?好烦人啊
