PHP检查数组值是否出现在所有多维数组中

function checkValueInArrays($value, $arrays) {
    foreach ($arrays as $array) {
        if (is_array($array)) {
            if (in_array($value, $array)) {
                continue;
            } else {
                return false;
            }
        } else {
            return false;
        }
    }
    return true;
}

$value = 'example';
$arrays = array(
    array('example', 'test'),
    array('example', 'sample'),
    array('example', 'demo')
);

if (checkValueInArrays($value, $arrays)) {
    echo "The value is present in all arrays.";
} else {
    echo "The value is not present in all arrays.";
}
