IF 或数组内的开关 - IF or Switch inside of an array

IF or Switch inside of an array

本文关键字：开关数组 IF | 更新日期: 2024-06-27

是否可以在数组中执行if/else或switch语句？

例如，我有这个数组

'images' => array(
          array(
                'link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer .'.jpg'
          ),
      ),

现在我想检查是否有超过 1 张图像，如果是，添加一个数组。我的想法是这样的，但它不起作用。

    <?php
$images = (string)$product->aantalfotos;
'images' => array(
    switch ($images) {
        case 1:
            array(
                'link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer .'.jpg'
            ),
        break;
        case 2:
            array(
                'link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer .'.jpg'
            ),
            array(
                'link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer .'_2.jpg'
            ),
        break;
        case 3:
            array(
                'link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer .'.jpg'
            ),
            array(
                'link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer .'_2.jpg'
            ),
            array(
                'link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer .'_3.jpg'
            ),
        break;
    }
),

试试这段代码：

<?php
$images = (string)$product->aantalfotos;
for ($working = array(), $i = 1, $suffix = ''; $i <= $images; $i++)
{
    $working[] = array('link' => 'http://graphics.edc-internet.nl/500/'.(string)$product->artikelnummer.$suffix.'.jpg');
    $suffix = '_'.($i + 1);
}
// Use $working in 'images' => $working
?>

你可以这样做：

安塔尔福托斯;

        switch($images) {
            case 1:
                $x = array('link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer . '.jpg');
            break;
            case 2:
                $x = array('link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer . '.jpg',
                    array('link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer . '_2.jpg'));
            break;
            case 3:
                $x = array('link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer . '.jpg',
                array('link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer . '_2.jpg'),
                array('link' => 'http://graphics.edc-internet.nl/500/' . (string)$product->artikelnummer . '_3.jpg'));
            break;
        }
if(!empty($x)) {
    $images[] = ($x);
}
print_r($images);
