I have an array like this:

[
    {
        "function_1": {
            "element": {
                "error": "0",
                "msg": "test"
            }
        }
    },
    {
        "function_1": {
            "element_2": {
                "error": "0",
                "msg": "test"
            }
        }
    },
    {
        "function_2": {
            "element": {
                "error": "0",
                "msg": "test"
            }
        }
    },
    {
        "function_2": {
            "element_2": {
                "error": "0",
                "msg": "test"
            }
        }
    }
]

I want output like this:

[
    {
        "function_1": {
            "element": {
                "error": "0",
                "msg": "test"
            },
            "element_2": {
                "error": "0",
                "msg": "test"
            }
        }
    },
    {
        "function_2": {
            "element": {
                "error": "0",
                "msg": "test"
            },
            "element_2": {
                "error": "0",
                "msg": "test"
            }
        }
    }
]

The answers that I found offered to search by name("function_1", "function_2"). But this does not suit me, the function will not always pass an array. I need exactly the "depth" or any other reasonable way. Thank you!

Your data structure looks weird for the purpose you are trying to achieve I'm bored af tho and created this code for you

function combineElementsPerfunction($functions) {

   $result = [];

    $uniqueFunctions = [];
    foreach ($functions as $function) {
        $functionName = array_keys($function)[0];
        $uniqueFunctions[] = $functionName;
    }
    $uniqueFunctions = array_unique($uniqueFunctions);
    foreach ($uniqueFunctions as $uniqueFunction) {
        $functionObjects = array_filter(
            $functions,
            function($function) use ($uniqueFunction) {
                $functionName = array_keys($function)[0];
                return $functionName === $uniqueFunction;
            }
        );
        
        $elements = [];
        foreach ($functionObjects as $functionObject) {
            $function = array_shift($functionObject);
            $elements = array_merge($elements, $function);
        }
        
        $result[] = [
            $uniqueFunction => $elements
        ];
    }
    return $result;
}
