Comparing two multi-associative arrays??

[Anon]

I need to be able to compare two three dimensional associative arrays. What I ultimately need to do is create a function that will return the differences between the two, if differences exist? I have tried many variations of the foreach construct, the for loop and the while loop but am having little or no concrete success. All I have been able to come up with so far is a function that will count the total number of elements in the arrays and compare that, but I need to know what the differences are if that check fails.

This is what I came up with to do the count, what follows is one attempt to do the comparison. Any help would be most appreciated. Thanks.

function countArray($arr) 
{   
    reset($arr);
    foreach($arr as $key => $value) {
        // echo"key, $key : value, $value<br>\n";
	    ++$count;
        if (is_array($value)) {
	        $second_level = $value;
            foreach ($second_level as $key => $value) {
                // echo"key, $key : value, $value<br>\n";
                ++$count;
                    if (is_array($value)) {
				        $third_level = $value;
                        foreach ($third_level as $key => $value) {
                            // echo"key, $key : value, $value<br>\n";
                            ++$count;
						        if (is_array($value)) {
				                    $fourth_level = $value;
                                    foreach ($fourth_level as $key => $value) {
                                        // echo"key, $key : value, $value<br>\n";
                                        ++$count;
				                    }
								}
				        }
                    }
            }
        }
    }

    return $count;

} 

My attempt:

function compareArrays($arr1, $arr2) 
{   
    reset($arr1);
	reset($arr2);
    // check top level elements
	foreach($arr1 as $key => $value) {
	    $result = array_diff($arr1, $arr2);
		if ($result) {
		    echo"Arrays do not match up in first dimension<br>";
		}
	    if (is_array($value)) {
	        $second_level = $value;
			    foreach($second_level as $key => $value) {
				    $array1 = $arr1[1];
					$array2 = $arr2[1];
                    $result = array_diff($array1, $array2);
                    if ($result) {
                        echo"Arrays do not match up in second dimension<br>";
                    }
                    if (is_array($value)) {
					    $third_level = $value;
			                foreach($third_level as $key => $value) {
                                $result = array_diff($arr1[2], $arr2[2]);
                                if ($result) {
                                    echo"Arrays do not match up in third dimension<br>";
                                }
							    if (is_array($value)) {
								    $fourth_level = $value;
			                            foreach($third_level as $key => $value) {
                                            $result = array_diff($arr1[3], $arr2[3]);
                                            if ($result) {
                                                echo"Arrays do not match up in fourth dimension<br>";
                                            }

										}
								}
							}
					}
				}
		}
	}

return $result;
