Fatal error: Call to undefined function mysql_connect() in C:\Chapter23\fig23_14_15\database.php on line 30

Hi am taking a  computer science Web course correspondence and need a little help.
I installed Apache 2.0,  PHP 5 and MySQL on my Window 7 computer.  I am using the text 4th Edition Internet & World Wide Web How to Program and in Chapter 23.5 entitled Connecting to a Database you are asked to execute the attached Products script which I did successfully.  The attached data.html file is an example of Querying a MYSQL database.  When I Select a field to display and then send the Query

http://localhost/phpscripts/fig23_14_15/database.php returns

Fatal error: Call to undefined function mysql_connect() in C:\Chapter23\fig23_14_15\database.php on line 30

and in the error log in apache shows the following for the incident:

[Sun Jan 06 18:12:09 2013] [client 127.0.0.1] File does not exist: C:/Apache/Apache2/htdocs/favicon.ico
[Sun Jan 06 18:12:15 2013] [client 127.0.0.1] PHP Fatal error:  Call to undefined function mysql_connect() in C:\\Chapter23\\fig23_14_15\\database.php on line 30, referer: http://localhost/phpscripts/fig23_14_15/data.html
[Sun Jan 06 18:12:15 2013] [client 127.0.0.1] File does not exist: C:/Apache/Apache2/htdocs/favicon.ico

My thinking is that I don't have MYSQL configured to work with Apache am I correct.  Please help

If MySQL isn't loaded when you run the phpinfo script, check to see if any of the extensions are loaded.  Based on your php.ini file your extension directory is set to  ./  

In your php.inin file you need to put in the path to your extension directory so it can find the php_mysql.dll.  This is what mine looks like....

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
extension_dir = "c:/LAMP/php53/ext"

Open in new window


You will want to change the path to point to your ext directory.  Using ./ on my system gave me the same undefined function error you are getting.

In 'php.ini', you need to enable the 'php_mysql.dll' extension by removing the ';' in front of it and restarting the server.

I removed the semicolon as seen in the attached file.  Stopped and restarted the server.  I still got the same error.

Create a test web page containing <?php phpinfo(); exit(); ?> and load it in your browser. Search the page for MySQL. If you don't see it, you need to recompile PHP with MySQL support,

Which version of PHP do you have?  As far as I know, all Windows versions are compiled with support for the MySQL drivers.

try initialising $database first

<?php

extract( $_POST );

$database = mysql_connect('localhost', 'iw3htp4', 'iw3htp4');

// build SELECT query
$query = "SELECT " . $select . " FROM books";

// Connect to MySQL
if (!$database) {
    die('Could not connect: ' . mysql_error());
}
// open Products database
if ( !mysql_select_db( "products", $database ) )
  die( "Could not open products database </body></html>" );

// query Products database
if ( !( $result = mysql_query( $query, $database ) ) ) 
    {
        print( "Could not execute query! <br />" );
        die( mysql_error() . "</body></html>" );
     } // end if

mysql_close( $database );
?>

Open in new window


also is the username and password correct.

hope this helps.

That did it.  So just to be clear I had to make the following edits in the php.ini file to resolve the issue:

1: Enable the 'php_mysql.dll' extension by removing the ';' in front of it and restarting the server.

2:  Put in the correct path for my extension_dir.

Thanks so much :) !
