Not sure, but it sounds like mysql is not enabled on your build of php.

Make a page with just this on it:
<?php
 echo phpinfo();
?>

save it to your web server and then see what it says.  

If mysql is enabled, you should see a table called mySQL and the next column should say 'enabled'

When I run a Web page with the function "phpinfo();", I can see there is option for PgSQL only.

However, I am sure that PgSQL has stopped and MySQL has started as I have checked in Linux.

What should the problem be?

 

by: davlun20080Posted on 2002-08-29 at 23:14:17ID: 7250712

If you do not see the listing for mysql, then mysql is NOT enabled in php.  You may have installed mysql on the server, but you did not enable it in php (or the version of php you have does not support mysql).

Check your documentation for your build or distribution of php to see how to enable mysql.

How can I enable MySQL?

What command(s) do I need to use?

I am sorry that I am a newer in Linux environment.

Could anyone help me?

you need to compil php with the mysql support

# ./configure --with-apxs=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql
# make
# make install

for instance

Don't forget to restart Apache

 

by: a.marshPosted on 2002-08-30 at 09:21:29ID: 7251791

What ./configure options did you specify when installing everything?

It's just that mysql is enabled by default in the version of PHP you are using, so did you explicitly set it to not be installed?

Ant

What version does the "configure" statement use for?

   # ./configure --with-apxs=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql

Does it work only when I install the source version and not the binary version?

 

by: us111Posted on 2002-09-03 at 05:45:08ID: 7258755

yes you need install the source distribution not the binary

"Error: "Fatal error: Call to unsupported or undefined function mysql_connect() in .." This means that your PHP version isn't compiled with MySQL support. You can either compile a dynamic MySQL module and load it into PHP or recompile PHP with built-in MySQL support. This is described in detail in the PHP manual. "

Can some one tell me how can I do this?

Along this subject: the "mysql_connect" error occurs to me on the command line, but not the browser.  My phpinfo says php 4.3.1 while command line php -v is 4.1.2. I'm trying to make the command line behave like web PHP or be able to use php 4.3.1 on the command line for cron processes. Any suggestions?

all i had to do was edit my php.ini and include a line like this:

in the [PHP] section

extension=mysql.so

i had some other extension= lines, and you'll want to make sure you have the php-mysql rpm installed too

# rpm -q php-mysql
php-mysql-4.3.11-1.norlug

One other thing to remember especially when installing "special" packes like from Fedora when upgrading (from PHP v4x.x to v5.x.x). You can not simply copy the /etc/php.ini file. Stupid me did this ... nothing worked. I checked all the above but still not working ... and finally I did a file compare, for example the loading of modules is changed from:
        extension_dir = /usr/lib/php
to
      extension_dir = /usr/lib/php/modules

This will cause for example in my case that mysql can not connect to the mysql module (took me a couple of days to find that out!). To avoid this type of errors; copy original /etc/php.ini to .org. Use tkdiff to look for the differences and open a second window to edit (is also possible with tkdiff but this leaves space for own interpretation ;-)).
      yum install tk
      yum install tkcvs

      tkdiff /etc/php.ini /nfsmounttoactiveolderserver/etc/php.ini &
      vi /etc/php.ini
