Can't connect with MySQL database, getting error "Fatal error: Class 'mysql_connect' not found in..."

Question

I am learning the core PHP and write the below code for testing the connection with the database. I get this error:

Fatal error: Class 'mysql_connect' not found in C:\xampp\htdocs\demo\index.php on line 4"

The code is below:

<?php
    $dbcon = new mysql_connect("localhost", "root", "");
    mysql_select_db("demo", $dbcon);

    $query = mysql_query("select name FROM test ");
    echo mysql_num_row($query);
    mysql_close($dbcon);
?>

who has told you this "new mysql_connect" ? Basicly removing 'new' will solve your current problem, but mysql_ extension is not recommended to be used anymore. — Royal Bg, Aug 12 '13 at 13:28

You cannot do new mysql_connect, mysql_connect is a function and not a Class.

Also please, don't use mysql_* functions in new code. They are no longer maintained and are officially deprecated. See the red box? Learn about prepared statements instead, and use PDO or MySQLi - this article will help you decide which. If you choose PDO, here is a good tutorial.

mysql_connect is not a class, you should drop the "new". See the documentation: http://fr.php.net/manual/en/function.mysql-connect.php

Also, mysql_ functions are deprecated.

Remove the 'new' keyword. That will be enough.

Change the below:

<?php
$dbcon = mysql_connect("localhost","root",""); <-- remove "new"
mysql_select_db("demo", $dbcon);

$query = mysql_query("select name FROM test ");
echo mysql_num_row($query);
mysql_close($dbcon);
?>

Also, you should use PDO or MySQLi instead of mysql_* as it is now deprecated.

thanks scott, now getting this "Call to undefined function mysql_num_row() in .." error – Chhatrapati Sharma Aug 12 '13 at 13:34
It's mysql_num_rows() see here: http://php.net/manual/en/function.mysql-num-rows.php – Scott Helme Aug 12 '13 at 13:37
You really should look to migrate to MySQLi or PDO, it's not too hard. Here is the equivalent MySQLi page: http://php.net/manual/en/mysqli-result.num-rows.php – Scott Helme Aug 12 '13 at 13:37
@ChhatrapatiSharma Why you don't read the docs before asking? – Royal Bg Aug 12 '13 at 13:37
