PHP stands for “PHP: Hypertext Preprocessor”

  • Order do matter (such as order of the functions)
  • Don’t let anything get lost in void, make it used by actually cramming it into one statement if possible
  • You can’t jump parameters
  • With parse-url you can create a script that verifies the URL
  • Don’t use isset, use empty
  • phpinfo()
  • php.ini: upload_max_filesize = 500M
