I have recently learned about the "mysqldump" in PHP. I try to execute the following commands, but when i do i get a blank file:

PHP Code:


system("mysqldump --opt -h $dbhost -u $dbuser -p $dbpass $dbname > $backupFile"); 


I'm currently running PHP5(Latest version) and i receive no errors when script is executed. Can somone help me?

Thanks in advance!

Show us please how does the command look like after substitution of all variables, and also what is the value of second argument to system() which you do not use right now.

First of all I can recommend to use absolute path to mysqldump.

have your user permission for run this command line ?

i dont know, i know that i can use the system() function though.

doesnt your host allow backups? I have tried 2 webhosts wiht php support on both and I have had the option to back up all my databases, usernames, files and everything else.
