Answer 1

A simple solution solved my problem. I just commented the:

"zend_extension = "d:/wamp/bin/php/php5.3.8/zend_ext/php_xdebug-2.1.2-5.3-vc9.dll"

in php.ini file. This extension was limiting the stack to 100 so I disabled it. The recursive function is now working as anticipated.

Answer 2

In case you are using Xdebug you might want to increase the max_nesting_level. Have a look at the Xdebug manual

xdebug.max_nesting_level

Type: integer, Default value: 100

Controls the protection mechanism for infinite recursion protection. The value of this setting is the maximum level of nested functions that are allowed before the script will be aborted.

Just add the value to your php.ini. I have mine at around 250 depending on the amount of tests you run and their complexity.
