I've found previous posts on this topic. I didn't understand all of the things to try. I tried what I could understand, but did not have any luck. Mostly just using xdebug_break(); ( again, no luck )

I am using Eclipse and Xdebug to debug a remote PHP web site. My problem is I can not get the debugger to stop on the breakpoints I set.

I am doing remote PHP development with Eclipse and a "Synchronized PHP Project. Nothing except Eclipse is running on my computer.

I am using the Xdebug debugger on the remote server through Eclipse.

When I use the debugger it will go to the index.php. I can step through for a while and see the value of variables.

The problem is that Xdebug will not stop at any of the breakpoints I set.

I am including my Xdebug settings

Any clues as to how to find and fix the problem would be welcome

Edit

I created an album of screen shots.

First one is an error message from Eclipse that happens when I leave it on all night.

The rest of the screen shots are pieces, in order ( top->down ) of my phpinfo output.

There is no Zend section in my phpinfo() output, though there are these vars

report_zend_debug = on
zend.detect_unicode On
zend.enable_gc  On
zend.multibyte  Off 
zend.script_encoding = no value

If you follow below steps I think it should work

Latest XDebug version

Your XDebug version is from 2015 as per this https://xdebug.org/. So you should upgrade to the latest version

Setting up XDebug configuration

Setup a 99-xdebug.ini in your /usr/local/etc/php/conf.d/ or /etc/php/conf.d or /etc/php/5.6/cli/conf.d depending on which exists on your system

xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_handler=dbgp
xdebug.remote_port=9000
xdebug.remote_autostart=1
xdebug.remote_log=/tmp/xdebug.log

Create a SSH Debug Tunnel

The machine from where you want to debug, you need to start a SSH tunnel using

ssh -R 127.0.0.1:9000:127.0.0.1:9000 -p 22 <user>@<phpserver>

Configure Remote Path mapping in Eclipse

Configure eclipse for the debugging on port 9000 and remote paths and now it should work
