Ask php to extend pear and pecl configurations from c # to php recently. according to the tutorial steps, I have not figured out some points. 1, after the pear extension is installed (the installation is successful by entering the pear command), why is there no HTMLQuickForm. php directory and file. 2. you cannot find the pecl compressed file downloaded from the official website in the tutorial. I think I have obsessive-compulsive disorder. I have never been clear about these two questions. I look forward to the answers from php experts. I am very grateful to ask php to extend pear and pecl configurations.

------ Solution ----------------------
Pear is a php class library developed by php enthusiasts. due to its long history and no authoritative management, the file layout is messy.
The pear command is used to install basic components. Other components must be installed with the-install component name)
Or go to the pear website to search for a compressed package.
Note: Due to many changes in the php kernel, most of the pear classes developed in php4 run normally.


Pecl is a collection of php extensions developed by php enthusiasts. because it is not officially developed by php, many of them fail due to lack of maintenance.
Php will also put some outdated extensions into pecl, and will also absorb useful extensions from pecl
Most of pecl only provides extended source code and needs to be compiled by yourself.
