Best PhP IDE?!

PHPStorm i love it but its paid

On mac I'll suggest you Nova prime. It's a native macOS app so lovely and so easy to work with.
If you okay with a heavy IDE so obviously go with PHPstorm it's hugely full-featured

sublime text, i prefer a plain editor over all

I used to use Netbeans IDE for a few months, it's very complete but it's far from being modern, currently I use VSCode which is quite complete if we add the necessary plugins to make the environment pleasant for PHP development.

phpstorm, everything jetbrains do is good

I have always used PhpStorm a cool program I advise

[font=-apple-system, BlinkMacSystemFont, Inter, Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol"]Sublime text[/font]
[font=-apple-system, BlinkMacSystemFont, Inter, Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol"]Notepad++[/font]
[font=-apple-system, BlinkMacSystemFont, Inter, Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol"]VisualCode[/font]

I'm using PHPStorm, there's really nothing better if you need something fully featured, otherwise use VS Code.

For my PHP development, I use Visual Studio Code. I used to use PHP Designer, but I find that Visual Studio Code is way more useful.

Still the best idea of Visual Studio Code, switched to it after Sublime Text. A huge number of plugins can solve any of your problems.
