How does PEAR differ from PECL in terms of PHP libraries?

PEAR (PHP Extension and Application Repository) is a package manager for PHP libraries that are written in PHP code, while PECL (PHP Extension Community Library) is a package manager for PHP extensions written in C code. PEAR is used for managing PHP libraries that can be easily included in PHP projects, while PECL is used for managing PHP extensions that provide additional functionality to PHP itself.
