 <?php
 /**
  * 批量运行sql文件
  * 正则分隔是重点 preg_split("/;[\r\n]+/", filecontent)
  */
 $config = require '../dataconfig.php';
 $dbhost = $config['DB_HOST'];
 $dbname = $config['DB_USER'];
 $dbpass = $config['DB_PWD'];
 $db_database = $config['DB_NAME'];
 $sqlfile = 'aa.sql'; //运行sql文件地址
 $db = new mysqli($dbhost, $dbname, $dbpass, $db_database) or die("连接数据库失败!");
 $db->query("set names 'utf8'");
 $sql_array = preg_split("/;[\r\n]+/", file_get_contents($sqlfile));
 foreach ($sql_array as $k => $v) {
     $result = $db->query($v);
     if ($result) {
         echo "Query OK<br/>";
     } else {
         echo $db->error() . '<br>';
     }
 }
 $db->close();
