果胶和梨的区别是什么?

I can see that GD library is for images. But I can't see differences between PECL and PEAR. Both have authentication. What are the main differences between two? Why don't they combine them?

我可以看到GD库是用于图像的。但是我看不出果胶和梨的区别。都有认证。两者的主要区别是什么?为什么不把它们结合起来呢?

PECL stands for PHP Extension Community Library, it has extensions written in C, that can be loaded into PHP to provide additional functionality. You need to have administrator rights, a C compiler and associated toolchain to install those extensions.

PECL表示PHP扩展社区库，它有用C编写的扩展，可以将这些扩展加载到PHP中，以提供附加功能。您需要拥有管理员权限、C编译器和相关的工具链来安装这些扩展。

PEAR is PHP Extension and Application Repository, it has libraries and code written IN php. Those you can simply download, install and include in your code.

PEAR是PHP扩展和应用程序存储库，它有用PHP编写的库和代码。您可以简单地下载、安装和包含在您的代码中。

So, yes they are similar, but yet so different :)

是的，它们是相似的，但又如此不同

pear is a php classes written in php Whereas pecl is extensions which not written in php and need compiling .

pear是用php编写的php类，而pecl是不使用php编写的扩展，需要编译。

#3

PECL is a repository of C extensions for PHP. Those extensions are usually installed via the pecl command, which is an alias for pear, with the default channel/repository set to pecl.php.net.

PECL是PHP的一个C扩展库。这些扩展通常通过pecl命令(pear的别名)安装，默认的通道/存储库设置为pecl.php.net。

PEAR is multiple things:

梨是多个方面:

The package installer (pear command) that is able to install packages from different channels (repositories), including pecl.php.net. Many consider composer the successor of the pear installer.
包安装程序(pear命令)，可以从不同的通道(储存库)安装包，包括pecl.php.net。许多人认为作曲家的梨安装。
The package repository http://pear.php.net/packages.php with ~600 libraries. Many of them are composer-installable.
包存储库http://pear.php.net/packages.php，包含大约600个库。它们中的许多都是可组装的。
A PHP coding standard that is available with PHP_CodeSniffer.
PHP_CodeSniffer提供的PHP编码标准。

PEAR as-such is not a coding standard. Instead PEAR "follows" a set coding standard that is encouraged within the PHP Community. This is however not the only coding standard that PHP users can follow, the ZF, for eg. recommends a slightly different standard.

梨本身并不是一种编码标准。相反，PEAR遵循的是PHP社区鼓励的一套编码标准。然而，这并不是PHP用户可以遵循的唯一编码标准，例如ZF。建议一个稍微不同的标准。

PEAR is also a coding standard ;-) php_codesniffer (install via $pear install php_codesniffer ) is a tool that will scan your code and hilight where it deviates from that or any other supported coding standard.

PEAR也是一种编码标准;-)php_codesniffer(通过$ PEAR安装php_codesniffer)是一种工具，可以扫描您的代码和hilight，使其偏离该标准或任何其他受支持的编码标准。
