Je was op zoek naar: functionality (Koreaans - Engels)

to emulate the functionality of add_next_index_*(), you can use this:
zend_hash_next_index_insert( ht, zval **new_element, sizeof(zval *), null)

the functionality part implements the functionality of the language (its functions, etc.).
to implement a web script interpreter, you need three parts:

returns an array of all apache response headers. this functionality is only available in php version 4.3.0 and greater.
this functionality is only available in php version 4.3.0 and greater.

the functions listed in this section work on local files, as well as remote files (provided that the wrapper supports this functionality!).

참고: this function is only available in php 4 compiled using --enable-exif. its functionality and behaviour has changed in php 4.2

php 4 was designed to be as compatible with earlier versions of php as possible and very little functionality was broken in the process. if you're really unsure about compatibility you should install php 4 in a test environment and run your scripts there.

this function registers a completion function. you must supply the name of an existing function which accepts a partial command line and returns an array of possible matches. this is the same kind of functionality you'd get if you hit your tab key while using bash.

"extending php" is easier said than done. php has evolved to a full-fledged tool consisting of a few megabytes of source code, and to hack a system like this quite a few things have to be learned and considered. when structuring this chapter, we finally decided on the "learn by doing" approach. this is not the most scientific and professional approach, but the method that's the most fun and gives the best end results. in the following sections, you'll learn quickly how to get the most basic extensions to work almost instantly. after that, you'll learn about zend's advanced api functionality. the alternative would have been to try to impart the functionality, design, tips, tricks, etc. as a whole, all at once, thus giving a complete look at the big picture before doing anything practical. although this is the "better" method, as no dirty hacks have to be made, it can be very frustrating as well as energy- and time-consuming, which is why we've decided on the direct approach.
