git clone https://github.com/longxinH/xhprof
cd xhprof/extension/
/usr/local/bin/phpize
./configure --with-php-config=/usr/local/bin//php-config
make && sudo make install

vim /usr/local/etc/php/7.1/php.in

最后引入扩展，并自定义输出目录
[xhprof]
extension = xhprof.so
xhprof.output_dir = /Users/liugx/work/php/xhprof

cd ..
