PHP - How To Store Configuration Settings.

I have a configuration file, and I use parse_ini_file() to parse it into an array at the initial entry point of my script.   I would like the settings to be available to all downstream scripts/methods/functions. Note that my intent is not to change them outside of the configuration file, and ideally they will be readonly, however, if not, I suppose that is okay and I will just be sure not to modify them.   I've read about dependency injection, and while this mostly makes sense, it seems like a lot of script/troubleshooting for little if any value for this scenario.   I've read that global variables are bad (couples your objects to some "god" object, cannot unit test, difficult to troubleshoot, difficult to work with multiple developers, potential conflicts with other classes, namespace pollution), but maybe not for this case?   Another option is defining a bunch of constants to the appropriate values, but this seems redundant.   Or maybe some static class with all the values?   What would be the best way to make configuration settings available to all PHP scripts, functions, and methods?

Dear All,

Greetings.  First time poster looking for some PHP help if it can be provided, because I'm confused as hell.

First off, I'll explain my situation.  I'm the IT technician of a small business tasked with ensuring the business' computers and website are running in top shape.  I originally joined as a Data Entry clerk to post products to the business' website, but got promoted when they original IT technician left town to pursue his PhD.  Before he left, he taught me a few things to prepare watching over the website as my new duty, including some PHP and MySQL.  Now, a few months after he's left, I have the glorious task of trying to move our website to a new host because we've apparently outgrown our original host's capabilities.  And being based on PHP with a MySQL database, it's turning out to be OH-so-fun.

So far, I've managed to download our entire website from the old host and given it to our new host to put up as a testing site, to ensure everything works before we switch hosts.  And for the most part, a lot of it has come together nicely, but there's still work needed to be done.  And thus we come to the problem I hope someone here can help with.

Our website has two back-end Admin sections, an older one that used to handle everything, and a newer one that's sleeker but still reads off a lot of data from the older one to work properly.  Normally, when you access those sections, you need to log in first.  Now, in the testing site, when I access those areas, the header of each of those sections now reads <?= $row[title] ?> and if I attempt to log in as normal, it just flashes back to the login page with the fields now cleared of what I typed in.  When I asked about this to see what the problem might be, the new host said it might "at least two misconfigurations on the new server relative to the old server".  So, I've been trying to Google for some help with PHP Configuration Functions, but I don't know if what I'm reading will help me fix the problem.  Would anyone here happen to know what they might mean in this case, because my knowledge of PHP is fairly limited beyond what I was taught to keep the website in order without considering a host change...

Thanks to those who help or can direct me to a place that helps!
