之前的開發，PHP的版本都是基於php7.3 。but!!!
接到一個老項目 tp3.1的。沒法用php7.3 只能在裝一個php5.6了。真坑爹。為啥還要TP3.1的項目。並且是剛開發的新項目。
真的很無語。。
MacOS Mojave 系統之后，如果想安裝 php5.6 版本的時候，無法用brew install php5.6 安裝，因為在新的 brew 中已經廢棄了 php5.6 ，如果使用 brew search php 搜索出來的Php版本最低是 php@7.1 的，所以有相關需求的可以按照下面方法安裝
添加源
1
brew tap exolnet/homebrew-deprecated
搜索PHP
1
brew search php
2 選擇
brew install exolnet/deprecated/php@5.6
安裝完后會提示如下信息：
==> php@5.6
To enable PHP in Apache add the following to httpd.conf and restart Apache:
LoadModule php5_module /usr/local/opt/php@5.6/lib/httpd/modules/libphp5.so
<FilesMatch .php$>
SetHandler application/x-httpd-php
Finally, check DirectoryIndex includes index.php
DirectoryIndex index.php index.html
The php.ini and php-fpm.ini file can be found in:
/usr/local/etc/php/5.6/
php@5.6 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have php@5.6 first in your PATH run:
echo 'export PATH="/usr/local/opt/php@5.6/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/php@5.6/sbin:$PATH"' >> ~/.bash_profile
For compilers to find php@5.6 you may need to set:
export LDFLAGS="-L/usr/local/opt/php@5.6/lib"
export CPPFLAGS="-I/usr/local/opt/php@5.6/include"
To have launchd start exolnet/deprecated/php@5.6 now and restart at login:
brew services start exolnet/deprecated/php@5.6
Or, if you don't want/need a background service you can just run:
sudo php-fpm
注意點
1 需要把php7.3的環境變量注釋
2 brew 停調php7.3
3 brew 開啟php5.6
換成了php5.6 😐
----------------------------------
1 brew services stop php@5.6
2 vim .zshrc 開啟要運行php版本的環境變量 =>php@7.2
3 source .zshrc
4 brew services start php@7.2
