Prolog is a utility for TNG testers, mod developers and anyone who wants to monitor their websites for PHP or user issues. It is an extension of the Show PHP Errors mod created by Roger Mitchell (decd) and provides three selectable levels of error logging: 1) just errors; 2) all errors, warnings and deprecations except for notices (default); or 3) all errors, warnings, notices, and deprecated functions.
Prolog is a utility for TNG testers, mod developers and anyone who wants to monitor their websites for PHP or user issues. It is an extension of the Show PHP Errors mod created by Roger Mitchell (decd) and provides nine selectable levels of error logging from Errors only to all errors, warnings, notices and deprecations.
''An important feature is that fatal errors displayed to the screen are generic and never reveal server information that a hacker may be looking for. The actual error can be found in the error log using the same timestamp shown on the screen.''
===<span style='color:#990000'>Important Note for TNGv14 Users</span>===
<p style='font-style:italic'>Prolog was updated for TNGv14. In Previous versions, Prolog was initialized in subroot.php. Starting with TNGv14, Prolog v14 is initialized in begin.php. This change makes it very important that you completely uninstall any previous versions you may have tried in TNGv14, before installing Prolog v14. '''Neglecting to do this may leave unwanted code in TNG files that will result in TNG errors and even site failure.'''</p>
<p>Prolog v14 will fail with errors if any components of previous versions have not been uninstalled.<p>
''An important feature is that fatal errors displayed to the screen are generic and never reveal server information that a hacker may be looking for.''
===Error Log Location===
Prolog will use the php.ini error_log setting to place its logs in the same location as PHP. If the php.ini is not set, or if it is inaccessible, prolog will use the TNG root-relative path you've set in the Mod Edit Options. If not set there, Prolog will create and default to a logs directory in your TNG root directory. While the last option works fine for offline test sites, for security reasons it is not recommended for a live site.
===php.ini error_log directive===
====php.ini error_log directive====
You must set the php.ini error_log directive with the full path to the PHP error log for the site. It can be located above the public_html for greater security (recommended.) In a local WAMP server you can edit it directly into the WAMPS php.ini file. On a shared hosting server you may be able to add a php.ini file to your root directory with just this directive to override the master php.ini. Some hosts allow a user.ini to serve the same purpose. See [[PHP error log]] for additional information on setting up error logs. The directive will look something like this ('''note the absolute server path'''):
You must set the '''php.ini error_log directive''' with the full server path to the PHP error log for the site. Error logs can be located above the public_html for greater security (recommended.)

On a shared hosting server you may be able to add a php.ini file to your root directory with just this directive to override the master php.ini. Some hosts allow a '''user.ini''' to serve the same purpose. See [[PHP error log]] for additional information on setting up error logs.

<pre>
<pre>
error_log = /home/mysite/mylogs/php_error.log
error_log = /home/mysite/mylogs/php_error.log
</pre>
</pre>
Both Prolog and the system will log errors to the PHP file. At the close of each GMT day Prolog will archive the PHP log to a dated backup and start the PHP log over again. After the first day no single log will contain more that one day's errors. That keeps all of them relatively small and manageable.
===Log Rotation===
Both Prolog and the PHP system will log errors to the PHP file. At the close of each GMT day Prolog will archive the PHP log to a dated backup and start the PHP log over again. After the first day no single log will contain more that one day's errors. That keeps all of them relatively small and manageable.
Prolog modifies subroot.php to add logging to all TNG pages. Scripts that work independently of TNG will not be logged by this mod; however, those errors will be logged by the system in the same PHP log.
''Prolog modifies subroot.php to add logging to all TNG pages. Scripts that work independently of TNG will not be logged by this mod; however, those errors will be logged by the system in the same PHP log.''
That said, if you do want to Prolog independent scripts, you can include prolog_conf.php at the top of a primary (as opposed to an included) script and as long as the mod remains installed, errors will be logged in the same way as TNG scripts to protect fatal errors from revealing server information.

* Daily logs selectable from drop down list for viewing and/or deletion (see visualization);
* Logs selectable from drop down list (see screen shot);

Compare the actual log entry with the displayed message above:
<pre>[24-Feb-2020 18:34:02 GMT] Fatal error: File access violation in fgw/fgw_setup.php on line 26

</pre>

This was probably a hack attempt. In this case the error was generated by the author of fgw_setup.php, not PHP itself.
This was probably a hack attempt. Both the displayed and logged errors were triggered by fgw_setup.php using the following code:

== Language Support ==
== Language Support ==
The mod support folder includes support for Czech, English, French, German, Spanish and Swedish. You can modify the files right in the support folder to change the translations. You can add new folders with other languages if you like. '''If you make changes or additions I will be happy to add them to the distribution package for others to use as well'''. Just email them to me or use the mod support link on the Prolog_Mod TNGWiki page.

See [[PHP error log]] for more complete information on setting up error logs in different environments
== More About Error Files and Log Dates ==
Archived error files and error items use the date set in the date.timezone directive in the php.ini file. If not set, GMT will be used.
On a ''live site with shared hosting'', you may be able to set the timezone by creating a php.ini file in your document root and entering directives, for example:
<pre>
date.timezone = America/Phoenix
error_log = /home/bisbeefa/mylogs/php_error.log
</pre>
It may take 20-30 minutes or more for the changes to take effect on shared hosting, so be patient.
You may also be able to add the following '''to your site's main .htaccess file''' for both error_log and date.timezone:
<pre>
<IfModule php7_module>
php_value date.timezone "America/Phoenix"
php_value error_log "/home/bisbeefa/mylogs/php_error.log"
</IfModule>
</pre>
If you are still using PHP 5, change the first line above to reflect that.
My web host (Bluehost) also uses the following:
<pre>
<IfModule lsapi_module>
php_value date.timezone "America/Phoenix"
php_value error_log "/home/bisbeefa/mylogs/php_error.log"
</IfModule>
</pre>
lsapi is a drop-in module to speed up serving PHP pages.

The error log file should use the extensions '''.log'''.
The error log file should use the extensions '''.log'''.
=== Setting the Error Level ===
=== Setting the Error Level for Logging ===
Error Level settings are designated by adding the index numbers for the items you want reported.
0 == ERRORS<br />
1 == WARNINGS<br />
2 == NOTICES<br />
4 == DEPRECATED<br />
9 == ALL
E_ERROR is always reported. Errors alone are index 0.
To specify E_ERROR and an additional type, enter the additional type index number into the parameter box. To specify a combination of error reporting, just add the index numbers and enter the total for the parameter.
* Error level 3 logs everything -- errors, notices, warnings and deprecations. Because TNG emotes large numbers of notices right now, error level 3 should only be used while actually testing a script and reduced back to 1 or 2 when not testing. Even a daily log can get very large at error level 3.
A complete map:<br />
0 == errors<br />
1 == errors and warnings (1)<br />
2 == errors and notices (2)<br />
3 == errors and warnings and notices (1+2)<br />
4 == errors and deprecated (4)<br />
5 == errors and warnings and deprecated (1+4)<br />
6 == errors and notices and deprecate (2+4)<br />
7 == errors and warnings and notices and deprecated (1+2+4)<br />
9 == E_ALL
* Error level 5 should be about right for a live site. It will log errors, warnings and PHP function deprecations. That latter means the scripts will stop working with new PHP upgrades, so we should know about them. Error level 1 would just be errors and warnings.
* Error level 9 logs everything -- errors, notices, warnings, deprecations and everything else. Because TNG emotes large numbers of notices right now, error level 3 should only be used while actually testing a script and reduced back to 1 or 5 when not testing. Even a daily log can get very large at error level 9.
