How did you test it? 
Have you php project and php file inside it? If yes have you something in logs? (ctr +3 and write error log)

There are several errors when creating a blank PHP project. I just have default PHP version set, no JS.
The project contains nothing but a "newfile.php". There are no othere errors I can see.
I just try to type ie. "array_ke", which should assist with ie. "array_key_exists".

Moving to PDT.

Can you right click on your project and select configure -> add php support?

Comment 4 Steven Rose

2015-09-18 11:01:08 EDT

No it is greyed out.
.project has a the PHP nature:

<?xml version="1.0" encoding="UTF-8"?>

Comment 5 Dawid Pakula

2015-09-18 11:09:24 EDT

Thanks. Can you also attach .buildpath file?

Comment 6 Steven Rose

2015-09-18 11:14:20 EDT

There is none.
But I have them in old projects from previous versions.
Content assist does not work there too (for internal functions).
Here is one:

<?xml version="1.0" encoding="UTF-8"?>
<buildpath>
	<buildpathentry combineaccessrules="false" kind="prj" path="/project1"/>
	<buildpathentry combineaccessrules="false" kind="prj" path="/project2"/>
	<buildpathentry combineaccessrules="false" kind="prj" path="/project3"/>
	<buildpathentry combineaccessrules="false" kind="prj" path="/project4"/>
	<buildpathentry kind="src" path=""/>
</buildpath>

Comment 7 Steven Rose

2015-09-18 11:24:34 EDT

Just found out:
in the old projects with .buildpath I can at least hover internal identifiers like "array_key_exists" or "Exception" and I get a content assist popup.
In both, old and new blank project, I do not get content assist suggestions when typing in an internal function name.
In the new blank project I just get "occurences of xxx" when hovering a internal function name.

Comment 8 Dawid Pakula

2015-09-18 11:48:42 EDT

Now is clear. Sometimes language container isn't properly added to buildpath.
To fix that please add this entry into your .buildpath file :

<buildpathentry kind="con" path="org.eclipse.php.core.LANGUAGE"/>

Something is wrong with DLTK ExternalFoldersManager. 
Did you change General / Workspace / Linked Resources settings?
Or can you check if exitsts projects inside $WORKSPACE_PATH/.metadata/.plugins/org.eclipse.dltk.core/.org.eclipse.dltk.core.external.folders ?

Comment 9 Steven Rose

2015-09-18 11:54:50 EDT

$WORKSPACE_PATH/.metadata/.plugins/org.eclipse.dltk.core/.org.eclipse.dltk.core.external.folders

has one file ".project" with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
	<name>.org.eclipse.dltk.core.external.folders</name>
	<comment></comment>
	<projects>
	</projects>
	<buildSpec>
	</buildSpec>
	<natures>
	</natures>
</projectDescription>

I did not change that setting you mentioned. At least not deliberately.
"Enable linked resources" is checked
Both "Drag and Drop" settings say "Prompt"
"Defined path variables" is an empty window

Comment 10 Steven Rose

2015-09-18 11:56:07 EDT

BTW. adding to .buildpath:

<buildpathentry kind="con" path="org.eclipse.php.core.LANGUAGE"/>

fixed the issue
