在php中连接数据有mysql_connect() 函数或mysql_pconnect()函数来完成,下面我给大家php入门者简单介绍介绍.
常用连接函数mysql_connect()
mysql_connect(servername,username,password);
长连接函数mysql_pconnect()
mysql_pconnect(servername,username,password);
PHP实例代码如下:
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
// some code说的是mysql_pconnect，怎么能绕开MySQL的设置,影响mysql_pconnect最重要的两个参数就是wait_timeout和interactive_timeout,代码如下:
<?php
$conn = mysql_pconnect("localhost","root","123456") or die("Can not connect to MySQL");
echo "MySQL线程号:". MySQL_thread_id($conn). "<br />";
echo "Apache进程号". getmypid();
