script for updating ip address on dyndns with ddclient if public ip changed

long time ago (very long) i set up a script which wrote the current date into a file and checked every hour whether the current date is different to that from the file .. and if so update dyndns …

pretty stupid .. right!

so i set up a new .. more reasonable one …

this one checks the current public ip address with the one set on dyndns ip (thanks!) ..

if it differs the dyndns ip is updated with the current public ip address …

zend debugger stopped working - apache errorlog [Zend Debugger] Debugger compile handler overriden

when trying to use the zend debugger today it just would not work …

looking into “window > preferences > debug > installed debugger” it showed me that i have xdebug and zend debugger installed …

a page suggested to remove xdebug … but when running phpinfo() it did not show anything about xdebug .. so that could not be the problem …

another page suggested to look into the error.log from apache where i read:

[Zend Debugger] Debugger compile handler overriden, will not be active in this request

when searching for this i found another page pointed me into the right direction .. (this one:

phil mentions that the problem is with running both zend debugger and the ioncube loader .. made me remember that i did install the ioncube loader last week …

his suggestion to remove the following line from php.ini did not work for me …


therefore i removed the zend loader … will set it up again when needed …

thanks phil!
