I only know PHP so I do all my coding in that language for 2 reasons.

1. I can run a PHP code from ANY browser, no need to download or god knows what
2. The php can access all my SQL Database from multiple domains (godaddy)

These 2 things are a must.
The problem is that when the PHP code is large and I run the PHP file on a browser it loads and loads and before it’s fully complete, it gets timedout.

I can probably find some timedout setting but that seems unreliable. What if the entire code needs 5 full minutes to complete? That’s though one thing I don’t like about PHP since it’s run on webserver it seems slow.
I heard of python but not sure where you even run it.

Any ideas on how I can resolve this or what programming language to switch to but STILL being able to do the 2 things above?

Thanks a bunch!!
