Is_writable returns false. I have a test. php file with the following content:
If (is_writable ("/home/www/testapp/image/cache "))
{
Echo ("can write! ");
}
Else
{
Echo ("can not write! ");
}
?>
Run the command line to return "can write !"
Php test. php
However, when you access the website, the returned result is can not write!
In addition, run the sudo-u apache php test. php command to return the can not write!
Run ps aux | grep apache to view the following user information:

The cache permission is changed to apache.
Drw-rw-2 apache 4096 October 20 22:18 cache
Drwxrwxrwx 3 apache 4096 January 16 2015 catalog
My question is, why is my website or apache account always rejected and cannot be written? thank you very much for your help !!
Reply to discussion (solution)
Php test. php is acceptable. it should be root.
Sudo-u apache php test. php does not work
Indicates that the user of apache has no write permission.
Catalog: this is 777. do you have the permission to write it?
No is_writable
I found the reason. because the parent folder does not have the permission, even if the sub-folder has the permission, it will not work. but thank you very much ~
