Xdebug successfully connects to DBGP clients, but won't stop at breakpoints

Question

I have Xdebug 2.1 installed, and running with PHP 5.2.13. It can successfully connect to multiple DBGP clients (i.e. the xdebug.remote_log shows communication

Answer 1

You must add the full path to the xdebug.so file, even when it's placed in the php/modules/ folder, as zend_extension doesn't looks in this folder by default.

If you have an exension=xdebug.so line, xdebug will load but it won't stop at breakpoints (beats me why).

Removing all exension=xdeabug.so (even from the cli ini file, which also loads) and adding the zend_extension will solve the issue.
