找到PHP“每个”警告的详细来源

I'm stuck on something that shouldn't exist. I have an each() warning that continuously pops up even though I've search in all of the Vendor's files and cannot find it.

This is my returned warning:

The each() function is deprecated. This message will be suppressed on further calls

To clarify, this is not my code, it is one of the Vendors packages used in a project I am working on, the unfortunate part is is that I have updated to the latest version of this code which was updated to specifically remove the each() function. That’s why I’m trying to locate where this error pops up at.

I do not get any additional information to locate where this issue might be located. What sort of configurations or error logging might I find useful?

each() has been DEPRECATED as of PHP 7.2.0. Relying on this function is highly discouraged.

Are you using an IDE which allows you to search all source files in your project for "each("?

Otherwise, you might be able to use a command line tool to do the same. How to grep a string in a directory and all its subdirectories (Linux)
