php-Mysql数据库用mysqli()与mysqli_connect()连接测试

PHP-mysqli()测试代码:
<?php
echo("Data link test: <br />---------------------------------<br />");
$db=@new mysqli("127.0.0.1","root","123456","jaes");
if(mysqli_connect_errno()){
echo("link data fail !");
echo mysqli_connect_error();
exit;
}
printf("Host information: %s <br />\n",$db->host_info);
$db->close();
echo("---------------------------------<br />link data success!");
?>

注意:如php不支持mysqli()时请在PHP.INI配置文件中将“;extension=php_mysqli.dll”修改为“extension=php_mysqli.dll”，如没有“;extension=php_mysqli.dll”的可自己创建,然后再重启Apache或IIS即可.

PHP-mysqli_connect()测试代码:
<?php
echo("Data link test: <br />---------------------------------<br />");
$link=mysqli_connect("127.0.0.1","root","123456","jaes");
if($link){
echo("link data success!");
mysqli_close($link);
}
else
echo("link data fail !");
?>
