How to Import a .sql File into a MySQL Database Using PHP: A Step-by-Step Guide?

How to Import a .sql File into a MySQL Database Using PHP

Importing a .sql file into a MySQL database using PHP can be easily accomplished, but requires careful attention to detail. Here's a detailed explanation:

Error Troubleshooting

Your error message indicates that the import file is not located in the same folder as your script. Ensure that the file path provided in the $mysqlImportFilename variable is correct and matches the location of your .sql file.

Alternative Approach

If you encounter issues with the exec() function, consider an alternative approach using the mysql_query() function as follows:

<code class="php"><?php

// Database connection details
$host = 'localhost';
$user = 'root';
$pass = '';
$db = 'test';

// Open connection
$conn = mysqli_connect($host, $user, $pass, $db);

// Read SQL file
$sql = file_get_contents('dbbackup.sql');

// Execute SQL queries
if (mysqli_multi_query($conn, $sql)) {
    echo 'Import file successfully imported.';
} else {
    echo 'Error importing file: ' . mysqli_error($conn);
}

// Close connection
mysqli_close($conn);

?></code>
Copy after login

Important Notes

  • The mysql_query() function is deprecated as of PHP 7.0.0, so it's recommended to use mysqli_query() or PDO instead.
  • When using the exec() function, ensure that the MySQL client is installed and accessible from the command line.
  • Make sure your database user has the necessary privileges to import the SQL file.
