1. junior positions available (you already did that)
2. local community/meetups available (bonus points if you have friends that could tutor you)
3. other paths to tech companies (i.e. have seen people starting as manual testers/doc-writers/L1 support, transfering later down the line to more technical positions, but not every org supports it)
Despite the bad rap it has gotten in its early days, PHP is fine and if you can learn it, you will be fine. Laravel and Symphone frameworks are used to-date and there still is a vibrant cottage-industry around wordpress-plugins.
Similarily, I know people that only know C# or only know Java and they get by just fine.
On the other hand, once you learn your third language and maybe expand to some more niche languages (i.e. I remember when I finally learned SQL, or dabbled in Clojure for a work project) you will realize it is not about the language.
I am not an expert at any of the languages (and somebody payed me to produce code in at least 8 of them) but I can manage and the pay is good :)
Not saying you should be jack-of-all trades, master of none, but if you are anxious about choosing your first language, I don't think it is as big of a deal in retrospect, as it might seem to you ;)
