Removing Elements from Multidimensional Arrays Based on Value

To remove elements from a multidimensional array based on a specific value, you can utilize the following method:

function removeElementWithValue($array, $key, $value) {
    foreach ($array as $subKey => $subArray) {
        if ($subArray[$key] == $value) {
            unset($array[$subKey]);
        }
    }
    return $array;
}

To utilize this function, pass in the multidimensional array, the key you're matching against, and the value you want to remove. For instance, to remove all sub-arrays where the "year" key has a value of 2011, call the function as follows:

$array = removeElementWithValue($array, "year", 2011);

This will modify the original $array by eliminating any sub-arrays meeting the specified criteria.
