The autocompleting search feature is accessible via the form elements at the top right of php.net pages. You should be able to use this feature in a reasonably modern browser by selecting the 'function list' search option and typing in some letters into the searchbox. Features:
- Dynamically changing list of function names starting with the substring you typed
- Navigate in the list with up and down keys
- Autocomplete with pressing the space key
- Go to a function by clicking on its name with your mouse
If you are not interested in this feature, you can turn it off for yourself on the My PHP.net page.
In case you find any bugs, we are interested in a detailed writeup, including JS error messages, operating system and browser information. The source code of this feature is released under the PHP License and is available from the PHP CVS server without any support.
