Toggle XDebug on and off

Christian (@penyaskito) is a dear friend of mine. I talk to him every day (usually text), but I have never blogged for him. This post should fix that.

He asked me today if I usually have XDebug turned on or off by default. I have it off, but I depend so much on it that I created a homegrown script to toggle it on and off quickly.

There are three tasks that I do with it:

xdebug-toggle status
xdebug-toggle off
xdebug-toggle on

This is the contents of my script, I use PHP-FPM + nginx + Linux. Consider this script under GPL-3.

#!/usr/bin/env bash

app="$(basename "$0")"
command="$1"
options="$2"

FILENAME_ON="/etc/php/7.3/mods-available/xdebug.ini"
FILENAME_OFF="/etc/php/7.3/mods-available/xdebug.ini.off"

php_ini=$(php -i|grep "Loaded Configuration File"|cut -d">" -f2|sed -e "s:^ *::g")
STATUS=$(stat ${FILENAME_ON} > /dev/null 2>&1 && echo enabled || echo disabled)

if [[ $command == "status" ]]
then
    echo $STATUS
    exit 0
fi

if [[ $command == "on" ]] && [[ $STATUS == "enabled" ]]
then
    echo "[NOTICE] Xdebug was already enabled."
    exit 0
fi
if [[ $command == "off" ]] && [[ $STATUS == "disabled" ]]
then
    echo "[NOTICE] Xdebug was already disabled."
    exit 0
fi

if [[ $command != "on" ]] && [[ $command != "off" ]]
then
  echo "Unrecognized command"
  exit 1
fi

if (($EUID != 0))
then
  if [[ -t 1 ]]; then
    sudo "$0" "$@"
  else
    exec 1>output_file
    gksu "$0 $@"
  fi
  exit
fi

if [[ $command == "on" ]]
then
    mv ${FILENAME_OFF} ${FILENAME_ON}
    systemctl restart php7.3-fpm
    systemctl restart nginx
    echo -n "Xdebug is now: "
    $0 status
    exit 0
fi

if [[ $command == "off" ]]
then
    mv ${FILENAME_ON} ${FILENAME_OFF}
    systemctl restart php7.3-fpm
    systemctl restart nginx
    echo -n "[INFO] Xdebug is now: "
    $0 status
    exit 0
fi
