You could set the authentification method to "trust" for the host the script is being run from, so you won't get a password prompt at all (see the pg_hba.conf file).

Subject: [ADMIN] Backup database through web and php
Hi all,
I am writing a php script to backup my postgres database through web interface, but my database is password required. When I do a pg_dump at the linux shell prompt, it will prompt for password in order to backup the database, does anyone know how to pass this password with the pg_dump command together so that I can do it using php system call?
