htaccess

The .htaccess-file is mainly separated in two parts

1. some php/apache-settings
2. rewrite rules for sefurls

The second part, the search engine friendly URLs and rewrite rules, are described in Rewrite Rules. See there for more information.

To activate

Tiki bundles a file named _htaccess. You should copy it to .htaccess

Alternatively, on Linux, you can make a symlink.

ln -s _htaccess .htaccess

PHP Settings

In some cases it is possible to overwrite some values from the php.ini file given by your ISP, by means of a file php.ini in the tiki root folder, or by means of some changes in the .htaccess file in the tiki root folder also. In this second case, place your special .htaccess file in the tiki root directory or just rename the _htaccess file given by Tiki to .htaccess an make your changes. You can visit tiki-phpinfo.php to check whether or not your changes where successful.

PHP Memory Limit

The most important setting is the php memory limit. The maximum amount of memory a script may consume. On many shared hosts this variable is set to 64MB. Tiki runs fine with 64MB but depending on your special needs and options it is necessary to uncomment and increase this value to 128MB. (which is the default value on recent PHP versions)

# memory limit
php_value memory_limit 256M

Error Display

To display php errors on your display activate / uncomment this setting. Error output is very useful during development, but it could be very dangerous in production environments. Depending on the code which is triggering the error, sensitive information could potentially leak out of your application such as database usernames and passwords or worse.

# to activate the error display, uncomment the following line
php_flag display_errors on

# to set the error_reporting level, uncomment the following line. Values are explained here: http://www.php.net/manual/en/errorfunc.constants.php
 php_value error_reporting E_ALL

Execution Time

PHP uses a default script execution time of 30s before a script is terminated by the server. In some cases with huge wiki pages with many plugins it´s necessary to increase the execution time to 90s

# increase execution time (default value in php use to be 30, and in some cases of long wiki pages with many plugins it may take longer)
php_value max_execution_time = 90     ; Maximum execution time of each script, in seconds
php_value max_input_time = 90 ; Maximum amount of time each script may spend parsing request data

Maximum File and Post Size

The maximum allowed size for uploaded files and maximum size of POST data that PHP will accept.

# increase the maximum file size for uploads allowed by php for Tiki (default value in apache use to be 2M which is usually too low for pdf or documents with some images, screenshots, etc)
php_value upload_max_filesize 10M
php_value post_max_size 11M

Include Path

# In some cases you may see open_basedir warnings about Smarty accessing php files that it shouldn't
# The following line (uncommented) will reset the include path to use only Tiki's files which will solve this in most cases
php_value include_path "."
