【env】mac下brew安装php及扩展（新）

Mac HomeBrew [2018-03-31]起弃用homebrew/php，php版本改名(如：php70 => php@7.0)，无法像以前直接搜索各个版本对应扩展直接安装如：brew install php70-redis，可采用pecl安装php对应扩展，以php@7.0为例

移除原来的homebrew/php tap

$ brew untap homebrew/tap

安装php@7.0

$ brew install php@7.0

pecl安装扩展

安装

# 查看pecl
$ pecl version
PEAR Version: 1.10.5
PHP Version: 7.0.30
Zend Engine Version: 3.0.0
Running on: Darwin Mac 17.5.0 Darwin Kernel Version 17.5.0: Mon Mar  5 22:24:32 PST 2018; root:xnu-4570.51.1~1/RELEASE_X86_64 x86_64

# 安装xdebug扩展
$ pecl install xdebug
...

Build process completed successfully
Installing '/usr/local/Cellar/php@7.0/7.0.30/pecl/20151012/xdebug.so'
install ok: channel://pecl.php.net/xdebug-2.6.0
Extension xdebug enabled in php.ini

扩展配置

# xdebug.so编译到了 /usr/local/Cellar/php@7.0/7.0.30/pecl/20151012/ 目录下
$ cd /usr/local/Cellar/php@7.0/7.0.30 && ll
total 256
...
lrwxr-xr-x   1 username  admin    23B  5  7 19:53 pecl -> /usr/local/lib/php/pecl
...
# `/usr/local/Cellar/php@7.0/7.0.30/pecl` 目录实际上软链到 `/usr/local/lib/php/pecl` 目录下
# 所以xdebug.so的实际目录为`/usr/local/lib/php/pecl/20151012/xdebug.so`

修改配置

# 查看php.ini目录
$ php --ini
....
Loaded Configuration File:         /usr/local/etc/php/7.0/php.ini
Scan for additional .ini files in: /usr/local/etc/php/7.0/conf.d
....

# 编辑php.ini
$ vim /usr/local/etc/php/7.0/php.ini
# 删除第一行:  zend_extension="xdebug.so" 

# 在`/usr/local/etc/php/7.0/conf.d`目录下新增xdebug.ini
$ vim /usr/local/etc/php/7.0/conf.d/xdebug.ini
# 加入以下内容
[xdebug]
zend_extension="/usr/local/lib/php/pecl/20151012/xdebug.so"
