Upgrading PHP in the CLI

Background

After installing Grav on a MAMP controlled local dev environment (this one, actually), I found that the grav Package manager (GMP) wouldn't run in the version of PHP that came with my Mac. The Mac was on version 5.5.38 when I started:

PHP 5.5.38 (cli) (built: Oct 29 2017 20:49:07) 
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2015 Zend Technologies

So what's a boy to do?

Attempt #1

Basically I found an article that instructed me to run a command in the shell that installs php 5.6 from some dude's repo somewhere, and then add it to my path. The command was/is:

$ curl -s http://php-osx.liip.ch/install.sh | bash -s 5.6

I got the instruction to add it to my path from the comments on this article. It was one of the follwing things:

$ export PATH="/usr/local/php/bin:/opt/local/share/man:/opt/local/bin:/opt/local/sbin:/usr/local/mysql/bin:$PATH"

or

$ export PATH=/usr/local/php5/bin:$PATH

I think it was the second. I'm fairly certain (though I didn't copypasta it) that the php -v command yielded the following after all these shenanigans:

PHP 5.6.0 (cli) (built: Oct 16 2014 08:24:05)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2014 Zend Technologies
with Xdebug v2.2.5, Copyright (c) 2002-2014, by Derick Rethans

And this worked just fine. GMP ran, everything seemed great. But I'm a nerd, so for whatever reason I wanted to do this with Homebrew.

Attempt #2

I found somewhere on the internet that Homebrew would handle all this for me, so I went ahead and deleted the PHP 5.6 that had been installed, and removed it form my path, and then hurridly went about using Homebrew to install it. Hallelujah!

Oh wait...

Turns out, all the PHP stuff had been deprecated about a year ago. But that didn't stop me from running brew install php in the CLI, and watching it download and install a BUNCH of packages. Everything except actual PHP, I think. And on top of that, I got a bunch of warnings about my OS being Too Old For This Shitâ„¢ and maybe things weren't gonna work all that well?

Sumbitch.

Attempt #3

So here's where I am now: I found an article on the Grav blog detailing how to actually do this with Homebrew, as well as some instructions for cleaning up my mess. Sweet.

So I followed those instructions, then I ran

$ brew tap exolnet/homebrew-deprecated

...which got me that keg. Keg? Yeah, I think so. Anyways, this keg is supposed to have all the deprecated PHP stuffs in it. Hallelujah! I decided I am only going to experiment with PHP 5.6 for the now, so I did a

$ brew install openldap libiconv

And that seemed to go just fine. openldap was already installed, so Homebrew installed libiconv for me, then the next command seemed to install PHP 5.6 just fine. I did see the following message here:

libiconv is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble.

If you need to have libiconv first in your PATH run: echo 'export PATH="/usr/local/opt/libiconv/bin:$PATH"' >> ~/.bash_profile

For compilers to find libiconv you may need to set:

export LDFLAGS="-L/usr/local/opt/libiconv/lib"

export CPPFLAGS="-I/usr/local/opt/libiconv/include"

So I might need to do something about that after a bit. Then we did a

$ brew install php@5.6

And got some warnings, and what is probably a failure message. Basically, I think this tutorial is for newer versions of the MacOS than I have, so it's not gonna work. I don't see php when I do a $ brew list and running this command tells me PHP 5.6 ain't installed:

$ brew link --force --overwrite php@5.6

So I think we're back to square one... or rather Attempt #1, to sort this out. I've just got SO much additional whatnot in here... here being in my Homebrew list.

Attempt #4 (and probably #5 if I'm being honest)

So I went back to the first article I had found that instructed me to run a command in the shell which installs php 5.6 from some dude's repo somewhere, and then add it to my path. Ran this:

$ curl -s http://php-osx.liip.ch/install.sh | bash -s 5.6

Then got to thinking that I oughtta attempt to clean up that Homebrew list, and since I had saved the Terminal output from the brew install php command I had run I was able to get a list of all the formulae that were installed as dependancies of php even though that formula didn't install. After some trial and error, I landed on this list to remove:

$ brew remove apr apr-util pkg-config gdbm readline sqlite xz python sphinx-doc cmake brotli cunit c-ares jansson jemalloc libev nghttp2 pcre argon2 aspell autoconf libidn libmetalink libssh2 openldap rtmpdump curl-openssl libtool unixodbc freetds libpng freetype automake libxml2 itstool docbook docbook-xsl icu4c boost source-highlight gtk-doc libffi httpd

So of course I "accidentally" re-brewed php@5.6 and the curl command didn't work. Good lord. Enter the actual site where the curl command came from to the rescue. I followed the Uninstall and Reinstall destructions, though I didn't find all the files and configs listed. But I did get all the extra Homebrew stuff uninstalled, dependancies removed, and finaly able to run the curl command successfully. Now I have a nice, neat version of PHP5.6 running in the CLI:

$ php -v

Salut!
