Running MySQL *.sql Files in PHP: An Effective Solution

Every now and then, the topic of executing MySQL .sql files from within PHP surfaces. Unfortunately, there's no straightforward solution, as .sql scripts often contain commands that cannot be executed directly as SQL statements.

The Edge Cases

Edge cases arise when *.sql scripts include built-in mysql tool commands not recognized by the MySQL server. These commands include CONNECT, TEE, STATUS, and DELIMITER.

A Reliable Approach

To address these challenges, it's recommended to invoke the mysql tool from PHP, employing a method like shell_exec(). This approach provides a robust solution for executing *.sql scripts.

Sample Code:

The following sample code demonstrates how to execute a *.sql script using shell_exec():

$command = "mysql --user={$vals['db_user']} --password='{$vals['db_pass']}' "
 . "-h {$vals['db_host']} -D {$vals['db_name']} < {$script_path}";

$output = shell_exec($command . '/shellexec.sql');

Alternative Approaches

Consider other related questions for alternative approaches to executing *.sql files:

• Loading .sql files from within PHP
• Is it possible to call a SQL script from a stored procedure in another SQL script?
• PHP: multiple SQL queries in one mysql_query statement

Remember to exercise caution when using shell_exec() to prevent potential security risks.
