PHP Upgrade
February 15, 2006 Posted in PHP
Upgrading PHP may affect installed PHP modules. For example, a PHP script reported the following error after I upgraded PHP:
PHP Warning: Unknown(): Unable to load dynamic library ‘/usr/local/lib/php/20020429/xml.so’ - Shared object "libexpat.so.5" not found, required by "xml.so" in Unknown on line 0
Reinstalling /usr/ports/textproc/php4-xml fixed it.

<?php passthru("uptime"); ?>
For more details about how to execute Unix/Linux command in PHP, please refer to PHP online manual.

register_globals
January 15, 2005 Posted in PHP
In my last post, I wrote: “PHP doesn’t need any configuration if installed with pkg_add”, well, this is not accurate, I found several php scripts worked weird, that reminded me of the famous parameter register_globals. It’s off by default, pkg_add doesn’t create php.ini, if you want to enable register_globals, you have to create a php.ini and modify the configuration, then restart Apache. Read More
