Terminal displays wrong php version (Snow Leopard)

问题

Need to downgrade php to 5.2.x, so I followed this tutorial: http://andreys.info/blog/2010-03-25/compile-php-5-2-on-osx-10-6-snow-leopard#comment-631

I'm on snow leopard 10.6.4, with xcode installed.

So I compiled php5.2.x and completed the tutorial. phpinfo() loaded within the browser at htp://localhost says 5.2.x, Great!! But, Terminal command "php --version" says 5.3.x ??

While compiling/installing php5.2.x, the new module file replaced the php5.3.x module here: /usr/libexec/apache2/libphp5.so

1. So where is Terminal getting 5.3.x from?
2. Do I have two php versions being loaded?
3. Should I even care?

回答1:

1. Check using which php. This should tell you which is being used.
2. Yes, looks like you have two installed at different locations.
3. Yes, mind what's being used where. Having multiple versions is absolutely valid (at least on a development or testing system) but you always should be aware of the versions being used.

For a more direct solution to the problem:

1. Rename the OLD version of PHP

   sudo mv /usr/bin/php /usr/bin/php5424

2. Create a Symbolic link for your new version of php so it can live in /usr/bin

   sudo ln -s /usr/local/php5/bin/php /usr/bin/php
