PHP mysqli扩展库-面向对象1

首先需要在php.ini当中启用如下配置。





程序实例(面向对象)

<?php
header("Content-type:text/html;charset=gbk");
//1,创建mysqli数据库对象
$mysqli=new
mysqli("localhost","root","123456","worddb");
if($mysqli->connect_error){
die("连接失败".$mysqli->connect_error);
}
//2,操作数据库
$sql="select * from words";
$res=$mysqli->query($sql);
while
($row=$res->fetch_row()){
foreach ($row as
$key=>$val){
echo "---$val";
}
echo
"<br/>";
}
//释放内存
$res->free();
//关闭连接
$mysqli->close();
?>

程序实例(面向过程)[/b]

<?php[/b]
//mysqli扩展库，面向过程编程

$mysqli=mysqli_connect("localhost","root","123456","worddb");
if(!$mysqli){
die("连接失败".mysqli_connect_errno($mysqli));
}
//向数据库发送sql语句
$sql="select * from words";
$res=mysqli_query($mysqli,$sql);
while ($row=mysqli_fetch_row($res)){
foreach ($row as $key=>$val){
echo "--$val";
}
echo "<br/>";
}
//关闭资源
mysqli_free_result($res);
mysqli_close($mysqli);
?>
