Accelerate PHP program development with Pear_PHP tutorial

Timely delivery of applications is the key to determining which technology to use for the solution. PHP will greatly facilitate its development process with the help of PEAR (PHP Extension and Application Repository: PHP Extension and Application Library). PEAR is a code library that provides pre-written classes for standard program functionality, significantly reducing application development time. PEAR is conceptually similar to Perl's CPAN. PEAR includes functional functions with rich features, including database, mail, and error handling. With PEAR, developers can deploy and enhance the basic functions they have already written while focusing on writing new features for their programs.
PEAR Basics
PEAR was created to provide a standardized way for developers to share PHP code and promote code reuse. The project is always under development, and users can submit their own code for inclusion in the PEAR library, which is bundled with PHP. All PEAR packages follow strict coding rules taking into account syntax and readability. The code consists of PHP or PHP extensions written in C.
Stig Bakken began working on the PEAR project in late 1999. His purpose is to create an organized code base that serves as a resource library for the PHP developer community. The project has grown very rapidly over the past two years and now contains a considerable amount of very useful reusable code. Although there are many other PHP code libraries, such as Zend's Code Gallery and PHP Builder's Source Code Snippet Library, etc., which are very famous, PEAR provides a standard that facilitates interoperability between functions. In addition, the code submitted to PEAR will undergo strict inspection, and such standards and inspection measures will ensure the quality and reliability of the code.

Available Functions
PEAR is divided into three categories: PEAR core components, PEAR packages and PECL packages . Core Component includes the base classes of PEAR and PEAR_Error as well as database, HTTP, logging and email functions. The PEAR package includes functions that provide authentication, networking, and file system features, as well as tools that use XML and HTML templates. The PECL package is an extension to PHP. It is written in C language and does not follow coding rules. Currently, all code in this category is experimental. To learn more about PEAR functionality please refer to the PEAR online manual.
If you are interested in submitting code to PEAR, you can achieve the above goals by joining the PEAR developer mailing list and asking everyone to check your code. However, you have to pay attention to the functions that have been included in the library and adhere to PEAR's coding rules.
Where to get PEAR
PEAR is bundled in the PHP distribution package. When you install PHP, PEAR is also installed. If you plan to get a stable version, and you can live without the latest PEAR version, then you can get the latest PHP version from the php.net download page. If you're adventurous and want to use the latest version of PEAR, you can download it using the CVS client by following the instructions for anonymous CVS access.
