Mac Enable Xdebug in MAMP

Below are the steps necessary to enable Xdebug in MAMP (non-pro version) for Mac.

Step 1: Determine PHP Version

  1. In MAMP, press Open start page
  2. View phpinfo to get PHP version
  3. Note which PHP version you have

Step 2: Configure php.ini

MAMP has two configuration files for each PHP version:

  • /Applications/MAMP/conf/php[version]/php.ini
  • /Applications/MAMP/bin/php/php[version]/conf/php.ini
  1. Locate the xdebug section at the bottom of both of these files
  2. Uncomment zend_extension line in both files (remove the ;)
  3. Add the following lines to the xdebug section in both files:
xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_connect_back=1    # Not safe for production servers
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true

Result should look something like:

[xdebug]
zend_extension="/Applications/MAMP/bin/php/php7.0.8/lib/php/extensions/no-debug-non-zts-20151012/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_connect_back=1    # Not safe for production servers
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true

Step 3: Restart MAMP!

  1. Restart MAMP and Xdebug should be all set for whatever environment you use!
  2. Visit the page you desire to debug with ?XDEBUG_SESSION_START=xdebug appended to the URL.
