PHP 8.1

[funderburkjim]

The webmaster of the sanskrit-lexicon at Cologne recently announced an upgrade to the PHP component of the server. PHP will be upgraded to version 8.1 (from the current 7.x). This upgrade is expected sometime after November 15, 2022.

The webmaster requested that we attempt to prepare the sanskrit-lexicon site for this change.

This note describes the steps I am taking in response to this request.

local installation upgrade

My current local installation has been using XAMPP version 8.0.0 (so the PHP version is 8.0.0).

The current XAMPP version is 8.1.10.

I upgraded the local installation to this latest version of XAMPP.

Approximately, here are the details for upgrading the local installation

• change location of current xampp installation from 'c:/xampp' to c:/xampp8.0.0'
• Download latest xampp (e.g. 8.1.10). Make the location of installation as 'c:/xampp'.
• Copy and paste several subdirectories of htdocs from the old to new folder
  • e.g. copy c:/xampp8.0.0/htdocs/cologne to c:/xampp/htdocs/
• start new xampp via xampp control panel.

Here are the folders copied in my particular installation.
The cologne folder is the main folder. The other folders are for personal reference. Other local installations do not need all these folders.

• cologne 40gb
• funderburkjim 7gb
• misc 1gb
• miscrepos <1gb
• sanskrit-lexicon 23gb
• sanskrit-lexicon-scans 3gb
• sqlite3 1mb
• venvs 50mb
• index.html

search displays for errors

I tried the various B/L/A/M displays, and also the simple-search display. A few small changes to some php modules were indicated by the presence in a display of php warning messages, or by a php warning message present in the browser error console.

Changes were made in the code in several repositories. The commit messages of these link to this issue.

regenerate b/l/a/m

Since only the csl-websanlexicon component changed (in particular, csl-pywork did not change), I reran scripts:

• sh redo_xampp_all.sh # local. in /c/xampp/htdocs/cologne/csl-websanlexicon/v02
• sh redo_cologne_all.sh # run on sanskrit-lexicon server.

Of course, I pushed the local changes to Github, then, on the Cologne server, pulled the repositories. The csl-apidev and csl-westergaard repositories have no initialization script to run.

php messages handled

This might be useful for other times, so here are the messages seen from php, that were 'corrected away'

-------------------------------------------------------------------
Errors encountered:
-----------------------------------
1. webtc1/http://localhost/cologne/md/web/webtc1/index.php
Deprecated: strlen(): Passing null to parameter #1 ($string) of type string is deprecated in

  Probably $data is an array.

Can you think of other likely spots where unexpected input might cause problems? please mention in a comment and I'll investigate.

The Cologne version of php can be found by https://sanskrit-lexicon.uni-koeln.de/php/phpinfo.php.

a display of php warning messages, or by a php warning message present in the browser error console.

Thanks for these small things that make a big difference.
