Hmm ... for some reason suddenly in one of the PHP projects i was working on i could not traverse the source code by clicking the function names,ect. I immediately realized that , some error must have occurred with my PHP builder settings. Fortunately i had several other projects where this feature worked. After comparing the “.project” file , i realized that putting the following entry will enable PHP Builder. I put the following after <projects> </projects>

<buildSpec>

<buildCommand>

<name>net.sourceforge.phpeclipse.parserbuilder</name>

<arguments>

</arguments>

</buildCommand>

</buildSpec>

<natures>

<nature>net.sourceforge.phpeclipse.phpnature</nature>

</natures>

and of course please make sure you have PHP perspective enabled in the first place.
