PEAR is an abbreviation for the PHP extension and application Library (the PHP Extension and application Repository) . It is a code repository for PHP extensions and Applications .

To put it simply,PEAR to PHP is like CPAN (Comprehensive perl Archive Network) to Perl.

In fact, the fundamental meaning is to tell us that sometimes not every technical detail must be our own realization, and pear is to let us stand on the shoulders of giants, can directly learn from or use other people have realized the mature code or ideas, so also reduce the possibility of detours, And the code that has been practiced is much safer and more efficient than the re-development.
