If this is due to an extension, how can I remove that extension?

It overwrites my custom snippet bothers me.

I disabled many extension but nothing changed.

Those icons indicate that those are Methods and Functions (not Snippets). See What do the Intellisense icons mean.

So you can try to disable two settings in your Settings UI:

Editor > Suggest: Show Methods
Editor > Suggest: Show Functions  - this looks like the right one to disable

Of course, there might be situations where you want to see Function suggestions, so you will have to see if disabling the setting is acceptable.

You can disable those Function suggestions for php files only with this setting (in your settings.json):

"[php]": {
  "editor.suggest.showFunctions": false
}

What you're seeing in your screenshot (suggestions for dba_<etc.>) are not coming from any extension. One can verify that by running the command Developer: Reload With Extensions Disabled and trying triggering suggestions again. So this is just functionality that comes out-of-box with a standard VS Code installation. You don't even need to install any PHP extension to get this.

As for your custom snippets getting "overwritten", it's hard to tell without more detail why this is happening. If you're on version 1.75, it might just be due to a bug that will be fixed later (Ex. As was the case in this other recent Q&A: Visual Studio Code's recent update is disrupting autocompletion).

As @Mark showed in their answer, these are function suggestions. You can disable function suggestions with the following setting:

"[php]": {
  "editor.suggest.showFunctions": false
}
