PHP에서 list() 함수를 사용하여 배열의 값을 변수에 할당하는 방법

<?php

function retInfo()
{
    $name = &#39;张三&#39;;
    $age = 18;
    $sex = 1;
    return array($name,$age,$sex);
}

list($name1,$age1,$sex1) = retInfo();

echo "name:${name1},age:${age1},sex:${sex1}\r\n";


list($name2,$age2,$sex2) = array(&#39;李四&#39;,19,2);

echo "name:${name2},age:${age2},sex:${sex2}\r\n";


?>

<?php
$arr_age = array(18, 20, 25);
list($wang, $li, $zhang) = $arr_age;
echo $wang;    //输出：18
echo $zhang;    //输出：25
?>

$result = mysql_query("SELECT id, username, email FROM user",$conn);
while(list($id, $username, $email) = mysql_fetch_row($result)) {
  echo "用户名：$username<br />";
  echo "电子邮箱：$email";
}

$arr_age = array(18, 20, 25);
list($a[0], $a[1], $a[2]) = $arr_age;
print_r($a);

Array ( [2] => 25 [1] => 20 [0] => 18 )
