What are some common methods for searching for specific values in multidimensional arrays in PHP?

When working with multidimensional arrays in PHP, it is common to need to search for specific values within the array. One way to achieve this is by using nested loops to iterate through the array and check each value. Another method is to use built-in array functions such as array_search or array_column to search for values within specific keys or columns of the array. 

// Example of searching for a specific value in a multidimensional array using nested loops
function searchValueInArray($array, $value) {
    foreach ($array as $subarray) {
        foreach ($subarray as $element) {
            if ($element === $value) {
                return true;
            }
        }
    }
    return false;
}

// Example of searching for a specific value in a multidimensional array using array_search
function searchValueInArray($array, $value) {
    foreach ($array as $subarray) {
        if (array_search($value, $subarray) !== false) {
            return true;
        }
    }
    return false;
}
