  probably due to file permissions. by default, most web servers run as an unprivileged user - so if they get compromised, they are unable to do anything of significance. your first example will work if you do the following at your linux prompt as root; cd /home mkdir test chmod 777 test/ this creates /home/test/ which is writable by all users. then simply change your first line to $file_name="/home/test/abc.crt" and run it. if this works, then you need to change your write permissions for wherever you want the file to be written to. this will be the same for your second piece of code; keep us posted. (just thinking; if you are running windows/iis instead - look at modifying the permissions of the folder you are writing to, by right clicking the folder, selecting 'properties' and then the 'security' tab. simple file sharing must be turned off for you to see the security tab)
