How to Troubleshoot and Effectively Import .sql Files into MySQL Using PHP?

Importing .sql Files into MySQL Using PHP

When attempting to import a .sql file through PHP code, users might encounter errors such as "There was an error during import." To resolve this issue, one should consider the following steps:

The provided code utilizes the deprecated mysql_ extension. For more stable functionality, consider switching to the mysqli or PDO_MySQL extensions. However, if using the mysql_ extension is necessary, ensure that it is installed and enabled in your PHP configuration.

Furthermore, the given code partially displays the input file's name and other crucial information. To avoid potential confusion, always ensure that the import file's path and name are correct. The file should be located in the same directory as the script and accessible by PHP.

Alternatively, a more comprehensive solution is available to import .sql files into MySQL:

// 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
mysql_connect($mysql_host, $mysql_username, $mysql_password) or die('Error connecting to MySQL server: ' . mysql_error());
// Select database
mysql_select_db($mysql_database) or die('Error selecting MySQL database: ' . mysql_error());

// Temporary variable, used to store current query
$templine = '';
// 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;

// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';')
{
    // Perform the query
    mysql_query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysql_error() . '<br /><br />');
    // Reset temp variable to empty
    $templine = '';
}
}
 echo "Tables imported successfully";

By incorporating these steps, you can efficiently import .sql files into MySQL databases using PHP, ensuring a smooth and error-free process.
