Question

I want to back up and roll back the back up on a database, and I’m trying to see what’s wrong:

‘mysqldump’ is not recognized as an internal or external command, operable program or batch file.

The above is what I get in the file that is exported. And this is what I run:

$database = 'logindb';

$backup = $location.'/'.$database.'_backup_'.date('Y').'_'.date('m').'_'.date('d').'.sql';

exec("mysqldump --opt -h localhost -u root logindb > $backup 2>&1", $output);
print_r($output);

As $location being my backup folder. So why do I get that error ?

And as additional info, I’m testing on localhost with XAAMP, the Apache server is running and MySQL is running as wel.

Answer 1

Because mysqldump is not in httpd user path.

I asume you work in Linux (or UNIX).

To know witch directory contains mysqldump you can execute whereis mysqldump.

Then you have two options:

• Check for mysqldump directory is in PATH environment variable of httpd user (usualy www-data user for apache server). And include it in PATH is it not present.

• Also you can execute mysqldump with full path:

Like this:

exec("/path_to_mysql_bins/mysqldump ...
