hi all i am getting following error while i am using php 5.2.12 and mysql4.1 in windows

Fatal error: Call to undefined function mysql_connect()

please help me to solve my problem

thanks in advance

    Run a phpinfo() to see if the php_mysql extension module is loaded.
    If it is not, you should activate mysql extension.
    For example in php.ini:
    extension=php_mysql.dll

    <?php

phpinfo();

?>

      Moved to Install forum. If enabling the "extesion=" line in your php.ini file doesn't work, read over the FAQ stickied at the top of this forum (specifically, the post entitled "2. PHP5 :: Can't use mysql_*() functions").

      If neither of those solves your problem, let us know.

        hi halojoy
        i am sending you following files containing my phpinfo files

          Thanks, but that does not show.

          Run this script I have made.
          Call the page: extensions.php and run it.

          <?php // extensions_list.php

$list = get_loaded_extensions();
$list2 = array_map('strtolower',$list);
sort($list2);
echo '<pre>'.print_r($list2,true).'</pre>';

?>

          If you have not [xx] => mysql
          on the list,
          then you have to activate php_mysql.dll
          in your php.ini
          change
          ;extension=php_mysql.dll
          to
          extension=php_mysql.dll

            hi halojoy
            my problem is still not solved
            i am sending php.ini and the extensions_list php output and httd.conf

              1. the list of extensions in my script
                shows you have not mysql and not mysqli extensions loaded

              2. your php.ini shows that BOTH should be loaded
                because this php.ini is correct

                ;extension=php_mime_magic.dll
                ;extension=php_ming.dll
                ;extension=php_msql.dll
                ;extension=php_mssql.dll
                extension=php_mysql.dll
                extension=php_mysqli.dll
                ;extension=php_oci8.dll
                ;extension=php_openssl.dll
                ;extension=php_pdo.dll
                ;extension=php_pdo_firebird.dll

              3. httpd.conf show that the php.ini used by *Apache is inside:

                LoadModule php5_module "C:\php\php5apache2.dll"
                AddType application/x-httpd-php .php
                PHPIniDir "c:/php"

              You should change
              PHPIniDir "to your php directory, which inlcudes your php.ini file"
              The php.ini you sent me.

              It happens sometimes, that Apache will use some old php.ini
              somewhere else in your PC
              where it is not where you think it is

              Running a phpinfo()

              <?php

phpinfo();

?>

              will tell you which php.ini is being used:
              It is called Loaded Configuration File

              Loaded Configuration File C:\Program\PHP\php.ini

                hi! im a newbie in setting up php 5, apache and mysql. please bear with me, please...need a help.

                Im using php 5.2.17, apache 2.2 and mysql 5.1.42. I

                my php codes are working in loading some pages, but when I tried connecting to MySQL, i got the same error. "Fatal error: Call to undefined function mysql_connect()"

                when i run test.php which has "<?php

                phpinfo();

                ?> "
                i have

                C:\php\php.ini for the Loaded Configuration File

                my php.ini is configured with:

                extension_dir = "C:\php\ext"

                extension=php_pdo.dll
                extension=php_pdo_mysql.dll
                extension=php_mysql.dll
                extension=php_mysqli.dll

                my libmysql.dll is in c:\php

                my httpd.conf has
                LoadModule php5_module "C:/php/php5apache2_2.dll"
                AddType application/x-httpd-php .php
                PHPIniDir "C:/php"

                I run the code:
                <?php // extensions_list.php

                $list = get_loaded_extensions();
                $list2 = array_map('strtolower',$list);
                sort($list2);
                echo '<pre>'.print_r($list2,true).'</pre>';

                ?>

                and it doesnt show the mysql.

                any help would be highly appreciated.

                  So did you read the thread you replied to?

                    More specifically, I don't see any mention of you verifying that the PHP installation directory is in your system's PATH environment variable. Have you done that? (If not, if you don't know, my FAQ entry here talks about this towards the end of the post.)

                    EDIT: Possibly even more important would be the preface to my FAQ entry:

                    Let me preface this FAQ by suggesting you ditch the MySQL extension - hey, the PHP team already did, that's why it's not enabled by default anymore! - and instead use a more robust set of functions/classes, such as [man]MySQLi[/man] or [man]PDO[/man].

                            Since (s)he hijacked an old thread, I doubt (s)he is able to do that. (However I'm going to mark it resolved anyway due to the thread necromancy plus the fact that this issue has been resolved a few times over.)
