JTAN runs the latest
version of PHP with the latest recommended php.ini file settings.
Some webmasters want different settings than these recommendations.
Since JTAN allows overrides in a .htaccess file, PHP settings can be changed with
a .htaccess file. This is an ordinary text
file that you put in the same directory
as your web site.
For example, if you want to turn off error
reports, you can have a file like this
php_flag error_reporting false
php_flag display_errors false
Or maybe you want to use the ill advised
global variable feature. If so, you can add
php_flag register_globals on
to your .htaccess file.
The php_flag directive is for true/false
boolean settings. For settings that take an
actual value, use php_value.
