I'm completely at loss here and am about to wipe my hard drive clean and start from a fresh OS install. I've been trying for two days to create a new yii app in the terminal and have finally figured out that the terminal or command line can not even execute PHP all of a sudden. I had no problem in past creating an executing php from the command line, But now it's not working. When I type which php i get nothing. When I type php -v I get:
-bash: php: command not found.
env: php: No such file or directory
Hopefully this will save someone a lot of headache. If, for whatever reason, you are unable to locate php in your command line, and unable to execute php from the command line, below is a list of steps to get PHP up and running again.
double check to make sure PHP is no where to be found by opening your terminal, and typing
find /usr -name php and hit enter. The main thing you want to look for here is a path with
the end. In my case it's, now that I've installed it, it's
/usr/local/php5-20120508-102213/bin/php. If you don't see anything like that then go to the next step. If you see something like that then make note of that path with the
/bin/php at the end, and go to step 4.
Go to the terminal and type in
curl -s http://php-osx.liip.ch/install.sh | bash -s 5.4,
hit enter. It will ask for your password. Your installing a php package. After you enter your password just follow the steps like any other download. For more information on that download you can visit the binary package website.
After you've installed php, open the terminal and type in
find /usr -name php and hit enter. You should see a few lines of paths. Make note of the one that has
/bin/php at the end of the path. You will be needing that path for the next step.
Next, open a text editor, I used TextWrangler for this purpose, go to file up in on the menu bar, and select Open file by name.Then type in
~/.bash_profile. Select Open and at the end of the .bash_profile file type in
PATH=$PATH:/usr/local/php5-20120508-102213/bin/ export PATH
/usr/local/php5-20120508-102213/bin/ part of that is the path that I mentioned to make note of, minus the php at the end. If your path was different, substitute it. Just remember to leave off the php at the end.
save and exit.
Last step, open the terminal and type in
php -v. Hit enter. You should see something like:
PHP 5.4.2 (cli) (built: May 8 2012 09:48:57) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies with Xdebug v2.2.0rc2, Copyright (c) 2002-2012, by Derick Rethans
if you're seeing that then everything is working.
