Clearly is a problem that will not be resolved anytime soon, but I have a suggestion that may help to make our lives easier:

Return questions about PHP using the stack snippets unnecessarily
[php] is:question with:stacksnippets:https://stackoverflow.com/search?q=%5Bphp%5D+is%3Aquestion+with%3Astacksnippets

with:image, then.
