How to Generate MySQL Dumps from a PHP File?

Dumping MySQL Data via a .php File

In an environment featuring a Linux system, MySQL, and PHP5, generating a mysqldump from within a .php file and storing it in a specified server location is a valuable capability. This article provides guidance for achieving this objective.

To initiate a mysqldump from within a .php file, employ the exec() function to trigger an external command. Executing a mysqldump requires specific parameters, including database user, password, host, and the database name itself. Additionally, it's recommended to redirect the output to a file rather than retrieving it as a string.

An example command for mysqldump might resemble:

mysqldump --user=... --password=... --host=... DB_NAME > /path/to/output/file.sql

Integrating this command into a .php file takes the following form:

exec('mysqldump --user=... --password=... --host=... DB_NAME > /path/to/output/file.sql');

Ensure that the connection details are correctly provided to establish a seamless connection with the MySQL server. With these considerations in mind, you can effectively generate mysqldumps from .php files and store them in designated locations on the server.
