在使用php程序时提示Warning: touch() [function.touch]:Utime failed:Permission denied in错误,下面一起来看看此问题的解决办法.

使用timthumb.php出现Warning: touch() [function.touch]: Utime failed: Permission denied in错误.

我们先来看一下touch()函数例子,touch() 函数设置指定文件的访问和修改时间.

touch(filename,time,atime)

例子,代码如下:

<?php touch("test.jpg");?>

应用例子时出现错误:用timthumb.php来做缩略图,本地测试很OK,但是放到vps上面就出现下面的错误错误提示:

Warning: touch() [function.touch]: Utime failed: Permission denied in /home/wordpress/wp-content/themes/zkeyword/library/timthumb.php on line 199

A TimThumb error has occured

The following error(s) occured:Could note create the index.html file - to fix this create an empty file named index.html file in the cache directory.

从字面上理解,是创建缓存的cache文件没有权限,我就直接将cache的权限设为0777,但是还是不行,还是提示权限不足,进入cache目录后还有一个index.html文件,将其设为0777,问题就解决了
