In the above code, assigning the anonymous functions to variables in the same code block works, if I assign them above.

If I assign them below, no go.

I'd like to be able to define those helper functions (ShowGreatThanZero and displayoutput) elsewhere, so that the code is neat and clean.

replacingAnonFunctions.php

 $showGreaterThanZero = function($value) {
            return $value["ID"] > 0;
        };
        
        $displayoutput = function($value) {
                  $this->DisplayTheOutput($value);
        };
    
        $collection = collect($this->tables);
        $filtered = $collection
            ->filter($showGreaterThanZero)
            ->pluck("Table")
            ->each($displayoutput);

The problem I am having is that there seems to be some data passed in, but I don't know what it's called in the context of the pass in.

for example here's an anonymous function:

$collection->filter(function($inbound) {
  return $inbound > 0;
});

If I want to replace the anonymous function with one I define in my class:

function take1($input) {
  return $input >0;
}

Then when I call it in the context of the collection object i don't know what to pass in:

$collection->filter($this->take1($WhatVariableIsUsedHere))

The filter is always a $value, $key I believe
