PHP函数返回数组

Question

我需要从函数返回多个值,因此我将它们添加到数组并返回数组.

<?

function data(){

$a = "abc";
$b = "def";
$c = "ghi";

return array($a, $b, $c);
}


?>

我怎么能接受的价值观$a,$b,$c通过调用上述功能？

Answer 1

您可以将数组键添加到返回值,然后使用这些键来打印数组值,如下所示:

function data() {
    $out['a'] = "abc";
    $out['b'] = "def";
    $out['c'] = "ghi";
    return $out;
}

$data = data();
echo $data['a'];
echo $data['b'];
echo $data['c'];

Answer 2

你可以这样做:

list($a, $b, $c) = data();

print "$a $b $c"; // "abc def ghi"

Answer 3

function give_array(){

    $a = "abc";
    $b = "def";
    $c = "ghi";

    return compact('a','b','c');
}


$my_array = give_array();

Answer 4

数据函数返回一个数组,因此您可以像访问数组元素一样访问函数的结果:

<?php
...
$result = data();

$a = $result[0];
$b = $result[1];
$c = $result[2];

或者你可以list()像@fredrik建议的那样使用这个函数在一行中做同样的事情.

Answer 5

$array  = data();

print_r($array);

Answer 6

从PHP 5.4开始,您可以利用数组解除引用并执行以下操作:

<?

function data()
{
    $retr_arr["a"] = "abc";
    $retr_arr["b"] = "def";
    $retr_arr["c"] = "ghi";

    return $retr_arr;
}

$a = data()["a"];    //$a = "abc"
$b = data()["b"];    //$b = "def"
$c = data()["c"];    //$c = "ghi"
?>

Answer 7

<?php
function demo($val,$val1){
    return $arr=array("value"=>$val,"value1"=>$val1);

}
$arr_rec=demo(25,30);
echo $arr_rec["value"];
echo $arr_rec["value1"];
?>
