You should use mysqli_connect
instead of mysql_connect
which is deprecated since PHP 5.5.0 :
$link = mysqli_connect("$host", "$username", "$password")or die("cannot connect");
mysqli_select_db($link, $db_name)or die("cannot select DB");
Try This:
Old way :
<?php
$link = mysql_connect('localhost', 'user', 'pass');
mysql_select_db('testdb', $link);
mysql_set_charset('UTF-8', $link);
?>
New way : all you gotta do is create a new PDO object. PDO's constructor takes at most 4 parameters, DSN, username, password, and an array of driver options.
A DSN is basically a string of options that tell PDO which driver to use, and the connection details... You can look up all the options here PDO MYSQL DSN
<?php
$db=new PDO('mysql:host=localhost;dbname=slr;charset=utf8mb4', 'root', '') or die("Could connect to Database");
?>
