PHP处理SQL脚本文件导入到MySQL的代码实例

 通常在制作安装程式，数据备份程序的时候会要用到这样的代码，我看网上有是有不太多，而且有些也不是很好用，有时候这种代码直接用现成的可以节省很多时间，那么我就从stackoverflow转了一个过来,需要的朋友可以参考下

代码如下:<?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
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";
?>
