13.18 Even More Things You Can Do with PHP
There are even more extensions and built-in functions available than
what's discussed in this chapter. Three good places
to look to learn about PHP's function library,
extensions, and add-ons are:
- The PHP Manual (http://www.php.net/manual/)
-
Available in 24 languages, the online PHP Manual has information about all of
PHP's built-in functions and lots of
user-contributed comments.
- The PEAR Package List (http://pear.php.net/packages.php)
-
PEAR is a collection
of hundreds of add-on packages to PHP. The DB package covered in
Chapter 7 is probably the most popular one.
This chapter highlights some others. When you need to solve a new
problem with PHP, check out PEAR before you start to write your code.
Someone may have already solved it for you.
- The PECL Package List (http://pecl.php.net/packages.php)
-
PECL is
another location for finding extensions to PHP. While the packages in
PEAR are themselves written in PHP, PECL packages are written in C
and provide access to external libraries or other resources.
