现在做的项目需要php连接mysql数据库,虽然之前学过,但是现在基本上都给忘了,之后通过查找相关资料找到了解决方法,下面小编把具体方法分享在平台供大家学习。

具体代码如下所示:

<&#63;php
//设置字符集
header('Content-Type: text/html; charset=utf8');
//连接数据库
$link = mysql_connect("localhost","root","123456");
if(!$link){
echo '数据库连接失败...<br>';
exit(-1);
}else{
echo "数据库连接成功...<br>";
}
//选择一个数据库作为默认数据库
mysql_select_db('php_sjk');
//执行sql插入语句
$sql = "INSERT INTO zh VALUES (NULL,'王杰','123456')";
$cr = mysql_query($sql);
//判断是否插入成功
if(!$cr){
echo "数据插入失败。<br>";
}else{
echo "数据插入成功。<br>";
}
//执行sql查询语句
$sql = "select * from zh";
$cr = mysql_query($sql);
//得到返回的结果集,并循环输出
echo "数据展示:<br><br><br>";
while($a = mysql_fetch_row($cr)){
echo "{$a[0]}——{$a[1]}——{$a[2]}<br>";
}
//关闭数据库连接
mysql_close($link);
&#63;>
