MySQL与PHP的连接无法正常工作
问题描述：
这是我的情况:
现在，我正尝试使用Apache服务器上的PHP文件连接到我的MySQL数据库:当我从终端运行PHP时，我的PHP可以连接到MySQL数据库(使用"php -f文件.php" )，但是当我从网页上执行它时，它只是无法连接.
I'm trying to connect to my MySQL database with a PHP file on my Apache server, now: my PHP can connect to the MySQL database when I run it from the terminal (using "php -f file.php") but when I execute it from a web page it just doesn't connect.
这是我的php文件:
echo "TRY CONNECTION";
$conn = mysql_connect($servername, $username, $password);
echo "EXECUTED CONNECTION";
Linux shell打印以下内容:
The Linux shell prints this:
尝试连接执行连接
TRY CONNECTIONEXECUTED CONNECTION
但是网页上会显示以下内容:
But the web page prints this:
:尝试连接
我尝试使用mysqli，但结果相同
I tried using mysqli but the result is the same
答
尝试一下
echo "TRY CONNECTION";
$conn =new mysqli($servername, $username, $password,$database);
echo "EXECUTED CONNECTION";
或者可能是
$con = mysqli_connect("localhost","my_user","my_password","my_db");
