MySQL中的MySQLdump，我需要将它转储到特定的目录中

Question

I run a script in one of my php files that dumps a specific database which works fine, but it puts the created file in the directory where the scripts is called. How can I make it to store the file in a specific directory? (eg /blahblah/backups)

Here's the code (the connection code is not included but you get the idea)

system("mysqldump -h $pdb_server -u $pdb_user -p$pdb_pwd $pdb_name > $backupfile");

could I just add

/path/to/output/$backupfile

Answer 1

Put the Path before the command:

system("cd /path/to/output/$backupfile; mysqldump -h $pdb_server -u $pdb_user -p$pdb_pwd $pdb_name > $backupfile");

or

system("mysqldump -h $pdb_server -u $pdb_user -p$pdb_pwd $pdb_name > /path/to/output/$backupfile");
