8 三章 函数返回多个值

返回多个值
    从函数中返回多个值很方便。使用一个很有用的语言构造list()就可以实现。利用list()构造可以很方便的从数组中获取值

<?php
        $color = array("red","blue","green");
        list($red,$blue,$green) = $color;
        echo "$red, $blue, $green ";

        function returnUserProfile()
        {
                $user[] = "jason";
                $user[] = "[e-mail]";
                $user[] = "english";
                return $user;
        }
        list($name,$email,$language) = returnUserProfile();
        echo "name:$nameemail:$emaillanguage:$language";
?>

red, blue, green
name:jason
email:[e-mail]
language:english
