将PHP版本升级到5.4.1，MAMP URL损坏了，所以降级了但是还是坏了？

Question

OK, so (retrospectively, quite stupidly), I upgraded my mac osx PHP version (not mamp php) from 5.3.28 to 5.4.10, to try and install composer. Now my MAMP sites don't seem to be loading. (I am not a backender.)

1. I upgraded mamp

At the end of the upgrade the final messages in terminal were as follows:

Create symlink /usr/local/php5/entropy-php.conf /etc/apache2/other/+php-osx.conf
Restarting Apache
httpd: Could not reliably determine the server's fully qualified domain name, using 192.168.0.2 for ServerName
Syntax OK

But when I checked the php version in terminal, it still said 5.3.28.

2. MAMP start page loaded, sites didn't work

Suddenly none of my MAMP sites were working. I have set the virtual hosts in httpd-vhosts.conf (and using sudo vim /etc/hosts). These have been working for like 3 years with no problem.

MAMP still loads the start page, but when I load a site I get:

Not Found
The requested URL / was not found on this server.
Apache/2.2.26 (Unix) PHP/5.4.41 DAV/2 Server at domain.dev Port 80

3. Reinstalled MAMP

So I then uninstalled and reinstalled MAMP, and restored all my settings, which again still loads up fine (the MAMP php version is now 5.6.7).

4. Tried downgrading mac php back to 5.3.28

I then tried to downgrade back to PHP 5.3.28, but that wouldn't work when I tried to use:

curl -s http://php-osx.liip.ch/install.sh | bash -s 5.3.28

So I just used:

curl -s http://php-osx.liip.ch/install.sh | bash -s 5.3

And it appears to have downgraded to 5.3.29 , but with the following error at the end:

Executing post-install script /tmp/5.3-frontenddev-post-install
Restarting Apache
httpd: Syntax error on line 665 of /private/etc/apache2/httpd.conf: Syntax error on line 8 of /etc/apache2/other/+php-osx.conf: Cannot load /usr/local/php5/libphp5.so into server: dlopen(/usr/local/php5/libphp5.so, 10): Symbol not found: _libiconv\n  Referenced from: /usr/local/php5/lib/libintl.8.dylib\n  Expected in: /usr/lib/libiconv.2.dylib\n in /usr/local/php5/lib/libintl.8.dylib

When I check the php version, it still says '5.3.28' :(

5. Someone save me

The exact same problem persists. I have no idea what's gone wrong or how to fix it. Any help would be super appreciated!

OK. So MAMP then stopped working completely. But against all odds, I managed to fix it.

I followed this guide and reinstalled PHP 5.3:

http://benedmunds.com/php/2014/10/16/fixing-homebrew-php-apache-after-yosemite/

I got an error when I got to this line:

$ brew reinstall php53 --with-mysql --with-pgsql --with-apache

---

So I followed the beginning of this guide: https://rtcamp.com/tutorials/mac/osx-brew-php-mysql-nginx/

Until I got to the install line tried it again to install 5.3:

brew search php

brew tap josegonzalez/php

brew tap homebrew/dupes

brew options php53

brew reinstall php53 --with-mysql --with-pgsql --with-apache

Took a little while, finished up. Restarted MAMP, and everything works again.

Phew.

Update

Had issues loading the MAMP start page too afterwards. Solved them by stopping OSX apache from running. It must have been taking over or something...

sudo apachectl stop
