ever heard of PSR? (PHP Standard Recommendations are like RFCs)

no? Nevermind.

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

“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

from user to dev:

• the positive:
  • php is easy to learn
  • php is usually “fast enough” (for web backends: it is slower than java but faster than python, but java needs A LOT more RAM)
• the critique:
  • php related environments might be a wee bit complicated to setup
• if the user wants to become a php dev check out bro’s excellent fun and easy php examples 🙂
  • just4info:
    • all those fancy php frameworks symphony sometime consisting of more than 10.000 files (thanks for making it open source but that’s a wee bit against unix kiss)
    • are just libraries that a dev wrote to use it, and while it HIGHLY might advance the user-soon-php-dev php-related-career they are NOT REQUIRED to get started, also:
      • if the user-soon-php-dev writes libraries + uses xdebug, the user-soon-php-dev is the only one who REALLY understands whats going on “under the hood” why things work or fail

keep it up and running:

• please consider
  • support the excellent xdebug project that makes server side PHP debugging a mild summer breeze
  • donating the great IDE with the superb team-compare-two-files-diff-view but massively-overcomplicated-menu-structure (too complex menus X-D) eclipse project
