Is there any reason to use PHP when starting a new SaaS project?

I'm a PHP developer, so when I started working on a new SaaS project I naturally planned from day 1 to do it in PHP.

For that reason, why should I chose PHP as my development language...

Can I use an instance variable as the key for an associative array?

The array is an instance variable of the same object.
