如何传递变量名称，因为它们在数组中

Question

<?php
function empty_values()
{
    $values = func_get_args();
    while (list(, $value) = each($values))
    {
        if (empty($value))
        {
            return false;
        }
    }
    return true;
}
?>

I want to pass the values from $_POST like this

if (empty_values(implode("," , $_POST)
{
    //some code
}

Answer 1

Use array_filter() instead and compare the length to the length of the $_POST array.

if (count($_POST) > count(array_filter($_POST))) {
    // At least one value was empty
}
