mac切换php版本shell脚本

1.获取php版本号

php -v | head -n 1 | awk -F " " '{print $2}'| awk -F "." '{print $1}'

php -v | awk '{if(NR==1)print}'|awk -F " " '{print $2}'|awk -F "." '{print $1}'

php -v | sed -n '1p' | awk -F " " '{print $2}' | awk -F "." '{print $1}'

2.正式代码

#!/bin/bash

ps -ef | grep php-fpm | grep -v grep > /dev/null

if [ $? -ne 0 ]; then

echo -e "php-fpm进程不存在！\n" 

else

killall php-fpm

if [ $? -eq 0 ]; then

        echo -e 'php-fpm进程删除成功！'

fi

fi

#获取php版本

PHP70_FAIL='brew unlink php70 执行失败'

PHP56_FAIL='brew unlink php56 执行失败'

PHP_VERSION=`php -v | head -n 1 | awk -F " " '{print $2}'| awk -F "." '{print $1}'`

if [ $PHP_VERSION -eq 7 ]; then

brew unlink php70 > /dev/null

if [ $? -ne 0 ]; then

echo $PHP70_FAIL

fi

brew link php56 > /dev/null

if [ $? -ne 0 ]; then

        echo $PHP56_FAIL

    fi

/usr/local/Cellar/php56/5.6.30_6/sbin/php56-fpm start > /dev/null 2>&1

if [ $? -ne 0 ]; then

        echo -e "php56-fpm 进程启动失败"

else

echo -e "php版本切换成功，当前版本[5.6]"

    fi

elif [ $PHP_VERSION -eq 5 ]; then

brew unlink php56 > /dev/null

if [ $? -ne 0 ]; then

        echo $PHP56_FAIL

    fi

    brew link php70 > /dev/null

if [ $? -ne 0 ]; then

        echo $PHP70_FAIL

    fi

/usr/local/Cellar/php70/7.0.18_10/sbin/php70-fpm start > /dev/null 2>&1

if [ $? -ne 0 ]; then

        echo -e "php70-fpm 进程启动失败"
