我正在尝试使用此代码连接到mySQL数据库,但我总是收到错误说
致命错误:未捕获错误:调用未定义函数mysql_connect()
这是我的代码;
<?php
$servername = "";
$user = "";
$pwd = "";
$dbname = "";
function connexion()
{
global $servername, $user, $pwd, $dbname;
$db=mysql_connect($servername,$user,$pwd) or die("Database connection failed: ".mysql_error());
mysql_select_db($dbname,$db);
}
?>
关键是在用户输入正确的输入后调用函数connecxion()
。你能告诉我我做错了吗?
答案 0 :(得分:0)
使用PDO(PHP数据对象)安全
<?php
try {
$yourHandler = new PDO('mysql:dbhost=127.0.0.1;dbname=yourdbname;', 'user', 'pass'); //creates a new instance of the PDO database class and passes it to your handler and creates database connection
$yourHandler->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); //sets the error mode so you can catch any errors that may occur
} catch (PDOException $e) {
echo $e->getMessage(); //echoes the errors
die(); //kills the page
}
?>
