Question

我在一个函数中有3个数组，我想返回它，因为它是用逗号分隔的。尝试了array_merge，array_combine，array_merge_recursive以及+运算符，但没有任何效果。

这是我的功能：

function svca_icon_fields() {

    $icon = array (
            'type' => 'dropdown',
            'heading' => __( 'Select Icon Type', 'svca-addon' ),
            'param_name' => 'icon_type',
            'description' => __( 'Select Icon Type', 'svca-addon' ),
            'value' => array(
                __( 'No Icon', 'svca-addon' ) => 'noicon',
                __( 'Font Awesome', 'svca-addon' ) => 'fontawesome',
                __( 'Open Iconic', 'svca-addon' ) => 'openiconic',
                __( 'Typicons', 'svca-addon' ) => 'typicons',
                __( 'Entypo', 'svca-addon' ) => 'entypo',
                __( 'Linecons', 'svca-addon' ) => 'linecons',
            ),
        );
    $fa = array(
            'type' => 'iconpicker',
            'value' => 'fa fa-star',
            'heading' => __( 'Icon', 'svca-addon' ),
            'param_name' => 'fa_icon',
            'description' => __( 'Pick an Icon to represent your package.', 'svca-addon' ),
            'settings' => array(
                'emptyIcon' => false,
                'type' => 'fontawesome',
                'iconsPerPage' => 200,
                ),
            'dependency' => array( 'element' => 'icon_type', 'value' => 'fontawesome' ),
        );
    $oi = array(
            'type' => 'iconpicker',
            'value' => 'vc-oi vc-oi-eye',
            'heading' => __( 'Icon', 'svca-addon' ),
            'param_name' => 'oi_icon',
            'description' => __( 'Pick an Icon to represent your package.', 'svca-addon' ),
            'settings' => array(
                'emptyIcon' => false,
                'type' => 'openiconic',
                'iconsPerPage' => 200,
            ),
            'dependency' => array( 'element' => 'icon_type', 'value' => 'openiconic' ),
        );

    $data = array_merge_recursive( $icon, $fa, $oi );
    //$data = array_merge( $icon, $fa, $oi );
    //$data = array_combine( $icon, $fa, $oi );
    //$data = $icon + $fa + $oi + $ti + $et + $li;
    //$data = $icon . $fa . $oi . $ti . $et . $li;

    //return $data;

    echo '<pre>';
    print_r( $data );
    echo '</pre>';      
}

而且，这就是我想要回归的内容：

array (
        'type' => 'dropdown',
        'heading' => __( 'Select Icon Type', 'svca-addon' ),
        'param_name' => 'icon_type',
        'description' => __( 'Select Icon Type', 'svca-addon' ),
        'value' => array(
            __( 'No Icon', 'svca-addon' ) => 'noicon',
            __( 'Font Awesome', 'svca-addon' ) => 'fontawesome',
            __( 'Open Iconic', 'svca-addon' ) => 'openiconic',
            __( 'Typicons', 'svca-addon' ) => 'typicons',
            __( 'Entypo', 'svca-addon' ) => 'entypo',
            __( 'Linecons', 'svca-addon' ) => 'linecons',
        ),
), //Seperated By Comma
array(
        'type' => 'iconpicker',
        'value' => 'fa fa-star',
        'heading' => __( 'Icon', 'svca-addon' ),
        'param_name' => 'fa_icon',
        'description' => __( 'Pick an Icon to represent your package.', 'svca-addon' ),
        'settings' => array(
            'emptyIcon' => false,
            'type' => 'fontawesome',
            'iconsPerPage' => 200,
            ),
        'dependency' => array( 'element' => 'icon_type', 'value' => 'fontawesome' ),
), //Seperated By Comma
array(
        'type' => 'iconpicker',
        'value' => 'vc-oi vc-oi-eye',
        'heading' => __( 'Icon', 'svca-addon' ),
        'param_name' => 'oi_icon',
        'description' => __( 'Pick an Icon to represent your package.', 'svca-addon' ),
        'settings' => array(
            'emptyIcon' => false,
            'type' => 'openiconic',
            'iconsPerPage' => 200,
        ),
        'dependency' => array( 'element' => 'icon_type', 'value' => 'openiconic' ),
), //Seperated By Comma

花了最近2个小时才弄清楚这一点没有成功感谢

Answer 1

这应该可以随心所欲地使用

return array($icon,$fa,$oi);

Answer 2

无法返回三个阵列。尝试返回包含三个数组内容的多维数组。

return array(your,arrays,here);

Answer 3

将其归还：

//your code above;
return array(
    'fa' => $fa,
    'oi' => $oi,
    'icon' => $icon
);

使用索引要容易一些，因此您无需记住订单。所以，如果

$a = svca_icon_fields();
$icon = $a['icon'];// instead of $a[2];

Answer 4

函数和方法只能返回一个值，因此必须返回：

$data = array( $icon, $fa, $oi );
$return $data;

但是，如果要将返回值分配给三个数组，可以这样做：

list( $icon, $fa, $oi ) = svca_icon_fields();

然后您将拥有三个不同的数组（您可以使用首选的数组名称更改$icon等）。 list()是一个php语言构造函数，它在一个操作中分配变量列表。请注意list()只能与非关联数组一起使用。
