Should I add extension=xdebug.so to load xdebug as a php module or not?

Question

First, http://xdebug.org/docs/install says

Note: You should ignore any prompts to add "extension=xdebug.so" to php.ini — this will cause problems.

Second, http://xdebug.org/docs/install says

Xdebug should appear twice there (once under 'PHP Modules' and once under 'Zend Modules').

Answer 1

The docs clearly say:

you still need to add the correct line to your php.ini: (don't forget to change the path and filename to the correct one — but make sure you use the full path)

zend_extension="/usr/local/php/modules/xdebug.so"

Note: You should ignore any prompts to add "extension=xdebug.so" to php.ini — this will cause problems.

Answer 2

if you add zend_extension="/usr/local/php/modules/xdebug.so" line in php.ini then IGNORE the prompt
