How to Import a .SQL File in MySQL Database Using PHP
When attempting to import a .SQL file into a MySQL database through PHP, you may encounter an error stating, "There was an error during import. Please make sure the import file is saved in the same folder as this script and check your values." To resolve this issue and successfully import the file, follow the steps outlined below:
The error message suggests that the problem lies in the PHP code you provided. Here's an alternative approach using the mysqli extension instead of the deprecated mysql_* functions:
<?php // Name of the file $filename = 'churc.sql'; // MySQL host $mysql_host = 'localhost'; // MySQL username $mysql_username = 'root'; // MySQL password $mysql_password = ''; // Database name $mysql_database = 'dump'; // Connect to MySQL server $mysqli = new mysqli($mysql_host, $mysql_username, $mysql_password, $mysql_database); // Check connection if ($mysqli->connect_error) { die('Error connecting to MySQL server: ' . $mysqli->connect_error); } // Read in entire file $lines = file($filename); // Loop through each line foreach ($lines as $line) { // Skip it if it's a comment if (substr($line, 0, 2) == '--' || $line == '') { continue; } // Execute the query if ($mysqli->query($line) === false) { echo 'Error performing query \'<strong>' . $line . '\': ' . $mysqli->error . '<br /><br />'; } } echo "Tables imported successfully"; $mysqli->close(); ?>
This code establishes a connection to the MySQL server using the mysqli extension. It then reads the contents of the .SQL file line by line and executes each line as a query. The mysqli->error property is used to handle any errors that may occur during query execution.
Remember to ensure that the .SQL file is located in the same directory as your PHP script, and that the database name, username, password, and host address specified in the code are correct.
