PHP Manual .chm index functionality not working as expected

Question

When I started working with PHP (like 10 years ago) the main thing that won me over, is the manual in .chm format. I used to keep the "Index" tab open, and type in there anything I needed and it'll direct me to a nice, concise but exhaustive reference page.

Now, today, I wanted to refresh my memory with some of the properties of isset(), so I typed it in the Index, but nothing relevant appeared. See for yourself in the screenshot below.

I had to find the page through the "Search" tab, which is less convenient.

I've noticed a similar issue before, but I ignored it. So, before posting a bug report or php.net, anyone knows what's happening here? Am I the only one with this problem, or is this another one of PHP's "improvements"?

Answer 1

This is a known bug. please vote on it, hopefully it'll get fixed. https://bugs.php.net/bug.php?id=64842

Answer 2

The problem is that the index doesn't include Variable handling Functions.

I guess thats because isset(), unset(), empty(), etc are not actual php functions but language constructs, and are therefor not included in the index.

Another reason they are different is because they cannot be called with variable functions

Answer 3

Index is created automatically on CHM files. It uses a keyword in a page to make its entry in index.

Refer to this link, if you want more information.

Answer 4

Here you could download an older version of the php manual in chm format.

If you have Windows XP or better you should right click on the chm and press the unlock button.
