I'm trying to rename a file with PHP but for some reason it doesnt work, do I have to activate some special permissions under PHP?
heres my code for the php file
<?php
if(!rename('file.php','filer.php'))
{
echo "Couldn't rename file!";
}
else
{
echo "file renamed succesfully!";
}
?>
I'm trying to rename a file on my /var/www directory when they sign out of a login area, so that way they cant access back hitting back button. Do I have an error on my code? Or is there another way to prevent this?
The Default permissions on this folder /var/www/ are: chmod 755 /var/www/
"read, write, and execute by owner" and "read and execute by the group and everyone else" (-rwxr-xr-x)
and the files inside the folder /var/www/file are: chmod 644 /var/www/file
I don't know if you have changed the Permissions or simply execute this command and it we'll work.
chmod 777 /var/www/file.php
"read, write, and execute by owner, group and everyone else"
Try this, then...it will make a copy of the file under a new name and them delete the original:
copy('file.php','filer.php');
unlink('file.php');
You aren't trying to move the file the code is being called from, are you?
PHP must have write access to the file. (I assume that you have a UNIX system). First find out which user PHP runs as, by running this command:
echo `whoami`;
in the PHP interpreter. (On my system that's www-data). Then run:
sudo chown www-data file.php
in the shell, in the same directory as the file you want. Of course, change www-data to the PHP user on your system. Make sure that the owner has write permissions. Then you're done; PHP can rename this file.
