How to update/replace php script on server -

i working on update feature cms. stuck on this. scenario user able upload zip file, updater script extract , replace old one.

i have problem replacing, i've done following

<?php rename($old, $new);

i "permission denied"

using ftp_rename:

<?php $conn = ftp_connect($host); ftp_login($conn, 'user', 'pass'); ftp_rename($conn, $src, $dest);

warning: ftp_rename(): rename failed. on....

is there proper way ? thanks.

depending on linux distro, php executes command specific user. check apache (or whatever server using) settings , put permission accordingly

for example in apache, set

export apache_run_user=www-data export apache_run_group=www-data

you can change upload folder owned www-data
