Category: Installation
Version: 1.7.0.1
Priority: normal
Status: new
Reported By: jeremy23

I have spent the better part of the morning trying to get Magento installed. Every time I submit at the database installation screen, I get the following message at the top:

PHP Extensions "0" must be loaded.

Looking through the code, it seems as though the return value of the function Mage_Install_Model_Installer_Db_Abstract::getRequiredExtensions() from app/code/core/Mage/Install/Model/Installer/Db/Abstract.php is returning Array( [0] => 0 ).

I modified the code in getRequiredExtensions() to "return Array();" at the top, and installation proceeded smoothly. This is but a hack, though.

This error also occurs when running install.php from the command-line:

# php5 -f install.php -- --license_agreement_accepted "yes" --locale "en_AU" --timezone "Australia/Sydney" --default_currency "AUD" # etc etc etc
FAILED
ERROR: PHP Extensions "0" must be loaded.

I have fulfilled all the PHP extension requirements, and magento-check.php says my "server meets the requirements for Magento".

Environment is a fresh install of Debian Wheezy, running Apache 2.2.22, PHP 5.4.5, MySQL 5.5.14, and the necessary PHP extensions from the Debian repository.

I have tested Magento 1.7.0.0 and 1.7.0.1, and both suffer from the same issue.

A forum user is having the same problem, but has had no response: http://www.magentocommerce.com/boards/viewthread/284882/

I'm facing the same issue with 1.7.0.1. magento-check.php says my "server meets the requirements for Magento", but getting PHP Extensions "0" must be loaded.]]> #2 / Comment by OzzyJohn

I'm seeing the same problem, recent install of Ubuntu 12.04 LTS LAMP server installed in virtualbox, only other things installed are

1. myphpadmin
2. webmin

This sounds like it might be debian related .. I might try with a redhat clean install and another ubuntu install without the other apps loaded.

The fix mentioned above does work, and given that it's only in the installer seems acceptable for the moment, nonetheless it would be nice to know what the root cause of the problem is

Another fix that was suggested was

The problem seems to be in wrong version PHP SimpleXML extension. Here?s another workaround:

Replace in file app/code/core/Mage/Install/etc/config.xml (near 71th string) this

<extensions>
<pdo_mysql/>
</extensions>

with this

<extensions>
<pdo_mysql>1</pdo_mysql>
</extensions>

Which seems to have worked for others, but did not work for me,

If anyone is interested the PDO info from phpinfo is as follows

PDO
PDO support enabled
PDO drivers mysql

pdo_mysql
PDO Driver for MySQL enabled
Client API version 5.5.27

Directive Local Value Master Value
pdo_mysql.default_socket /var/run/mysqld/mysqld.sock /var/run/mysqld/mysqld.sock]]> #3 / Comment by major_impact

I tested it and can confirm that this bug is present.

The current version of magento is not installable without the modfications described above. :-/]]> #4 / Comment by devplayer

same problem with magento 1.7.0.2 and PHP Version 5.4.6-1ubuntu1.1 , the same fix '<pdo_mysql>1</pdo_mysql>' in config.xml does the trick]]> #5 / Comment by Appmerce

This happens because Magento could not determine the version of MySQL, or could not detect MySQL. I am using MySQL 5.5.29 and PHP 5.4.10 on Apache 2.4.2]]>
