PHP を使用してエラーが発生せずに .sql ファイルを MySQL データベースにインポートする方法

<code class="php"><?php

// File name
$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());

// Declare variables
$templine = '';
$lines = file($filename);

// Iterate through file lines
foreach ($lines as $line) {
    // Ignore comments and empty lines
    if (substr($line, 0, 2) == '--' || $line == '') {
        continue;
    }

    // Append line to temporary query
    $templine .= $line;
    // Check for semicolon to mark end of query
    if (substr(trim($line), -1, 1) == ';') {
        // Execute query and handle errors
        mysql_query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysql_error() . '<br /><br />');
        // Reset temporary query
        $templine = '';
    }
}

// Success message
echo "Tables imported successfully";
