some devs make jokes about PHP – but this – only PHP + XDEBUG can do!

  • setup a test-server with test requests and data and start debug session with the REAL requests that start a debug-session in eclipse to look into the code step-debugging what is going on-and-wrong and find the problem with this particular input
    • python can only do this for files, not requests (also python is slower)
  • develop DIRECTLY on this test-server
    • then git commit git pull aka sync-copy results to production

“show me the src”: https://github.com/xdebug/xdebug

how to set it up?

some find it hard to setup and it can be a bit tricky, so prepared a ready2go virtualbox disk images (3.2GB download).

support the software:

so the software can support the developer, so the developer can support the user:

“where does the money go?” wow look at this: https://xdebug.org/log

really would wish every project had this kind of transparency 😀

PS: DEFINATELY DISABLE OPCACHE DURING DEVELOPMENT! X-D “why does this variable have values from yesterday?” “strange” (it was OPCACHED)

# where are the config files?
# 1) way look: info.php

echo '<?php phpinfo();' > /var/www/html/info.php
# open info.php in browser and Ctrl+F search for php.ini

# 2) way:
php --ini
