php配置Mysql后测试报 Call to undefined function mysql_connect()....

windows下配置，在用phpinfo()能显示mysqli，但是在用mysql_connect就会报错 Uncaught Error: Call to undefined function mysql_connect() in D:\LAMP\Apache24\htdocs\first.php:14 Stack trace: #0 {main} thrown in D:\LAMP\Apache24\htdocs\first.php on line 14

#mysqli的简单用法 
<?php
	$dbhost ="127.0.0.1";
	$dbuser = "root";
	$dbpwd = "123456";
	$dbname = "test";
	$charName = "'UTF8'"; //设置查询字符集gbk,gbk2312,utf-8

	$mysqli = new  mysqli($dbhost,$dbuser,$dbpwd,$dbname);
	if (mysqli_connect_errno()){ //注意mysqli_connect_error()新特性
		die('Unable to connect!'). mysqli_connect_error();
	}
	$sql = "SET NAMES ".$charName;
	$mysqli->query($sql);
	//$mysqli->query("SET NAMES 'UTF8'");
	
?>
 用mysqli 就不在使用mysql_connect了  高版本 使用mysql_connect 会出警告的
