it doesn't work with all plugins dude i tried it

so rewrite it manually

is there a phar for a php7 server but supports php5? except pocketmine, genisys, and imagicalmine?

how to rewrite it? as in everything...?

Follow the last introduction. Oh! And you now how to load plugins without compress it into .phar .
Load it. See the errors on Console? Google it, fix it, you done.

i use php5 plugin on my php7 server, the problem isnt about php, ur problem is update ur old api to new api on php7 pocketmine

oh

so how to change the api?

What about changing plugin.yml ?

PHP:

name: MyPlugin
version: 1.0.0
main: MyPlugin\Main
api: 2.0.0

That's the api. Change it yourself to the PocketMine new API.
