Osx-why is the php version displayed on the terminal different from the php version used by Apache?

The system comes with php 5.5.27, And I have installed php 5.3.29 myself. In the terminal, the php-v version is 5.3.29, but when the browser opens localhost, it uses 5.5.27. It is strange, why? How can I use 5.3 For localhost? The built-in php is 5.5.27I installed 5.3.29. Use in a terminal Php-vThe version is 5.3.29But when the browser opens localhost 5.5.27That's strange. Why? How can I use localhost? 5.3?

1. Start 5.3 of php-fpm. If nginx is used as the web server
2. Modify the php parsing configuration in the web server configuration file. If nginx is used, modify fastcgi_pass. If apache is used, modify LoadModule and AddType.

Php-v displays the php version configured in environment variables.
The version displayed for localhost access is the php version loaded by the Apache or nginx configuration file.
