Could someone help with this plugin?

If someone could point out what I have done wrong and how to update it to php7, that would be greatly appreciated!

You're uploading the raw contents of a phar file?

Tried my best to fix it was hard to read

Can you upload the zip of your plugin? You can't modify a plugin when it's in phar format.

Thank you so much!!!

Hey,u would not believe how little I know about this stuff. I started 5 days ago... I have yet to learn what u r talking about thank you anyway!!

I am HUUGGE nube at this. I started a few days ago,I definitely need some coaching

@SliperyPlayz You compiled the plugin right? Or did you put all your code into a .phar file?

Exactly how u see it,that's how I built it

Ok so you saved it as a .phar file?

Yeeeeaaaahhhhhh.sorta I have just looked at a bunch of other similar plugins and tried to stitch this together (#nocomputer) and I am on IOS sooooo... I know it's pretty hooky but ya know,work with what ya can right?

The source code needs to be put in the right plugin format and them compiled into a .phar with DevTools or go to pmt.mcpe.me

I don't suppose u are able to do that,are you :/

A phar file contains a lot of binary bytes. You can't edit it directly (at least not through conventional editors), just like you can't edit a Microsoft Word file directly.
