PHP MySQL入門教程之串連資料庫

常用串連函數mysql_connect()

mysql_connect(servername,username,password);

長串連函數mysql_pconnect()

mysql_pconnect(servername,username,password);

代碼如下	複製代碼
<?php $con = mysql_connect("localhost","peter","abc123"); if (!$con)  {  die('Could not connect: ' . mysql_error());  } // some code ?>

說的是mysql_pconnect，怎麼能繞開MySQL的設定。影響mysql_pconnect最重要的兩個參數就是wait_timeout和interactive_timeout

代碼如下	複製代碼
<?php     $conn = mysql_pconnect("localhost","root","123456") or die("Can not connect to MySQL");     echo "MySQL線程號:". MySQL_thread_id($conn). "<br />";     echo "Apache進程號". getmypid(); ?>
