How to give write permission to a folder

chmod()

[avictor]

Hai,

I uploaded my php website in the server. In my website I have included comment box functionality. But I am getting this error
Warning: chmod(): Operation not permitted in /home/nmp1/public_html/comments/comments.php on line 457

Can I give write permission to that particular folder

then you have to login to a shell and issue a chmod from the command line

keep in mind that changing write permissions can cause very serious security concerns
