Deprecated: mysql_connect()

Question

I am getting this warning, but the program still runs correctly.

The MySQL code is showing me a message in PHP:

Deprecated: mysql_connect(): T

Answer 1

put this in your php page.

ini_set("error_reporting", E_ALL & ~E_DEPRECATED); 

Answer 2

There are a few solutions to your problem.

The way with MySQLi would be like this:

<?php
$connection = mysqli_connect('localhost', 'username', 'password', 'database');

To run database queries is also simple and nearly identical with the old way:

<?php
// Old way
mysql_query('CREATE TEMPORARY TABLE `table`', $connection);
// New way
mysqli_query($connection, 'CREATE TEMPORARY TABLE `table`');

Turn off all deprecated warnings including them from mysql_*:

<?php
error_reporting(E_ALL ^ E_DEPRECATED);

The Exact file and line location which needs to be replaced is "/System/Startup.php > line: 2 " error_reporting(E_All); replace with error_reporting(E_ALL ^ E_DEPRECATED);

Answer 3

Well, i just faced such message today when i moved to new hosting! anyway i have tried to change the "mySQL" to "mySQLi" but not working, so i have done this:

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
# Turn off all error reporting
error_reporting(0);
$connect_myconn = "Database Connection";
$hostname_myconn = "localhost";
$database_myconn = "db name";
$username_myconn = "user name";
$password_myconn = "pass";
$myconn = mysql_connect($hostname_myconn, $username_myconn, $password_myconn) or die("<h1 style=margin:0;>A MySQL error has occurred.</h1><p><b>Your Query:</b> " . $connect_myconn . "<br /> <b>Error Number:</b> (" . mysql_errno() . ")</p>" . mysql_error());
mysql_select_db($database_myconn, $myconn);
?>

The trick is to set error reporting off :)

# Turn off all error reporting
error_reporting(0);

For PHP 7+ you can use this code instead:

ini_set('display_errors', 0);
ini_set('log_errors', 1);

Thanks
