在数组中输出文本字符串

Question

如何在PHP中的数组中打印以下字符串，只选择小写文本：

{"fieldValue":[{"portfoliocategory":"Printing","portfoliocategoryid":"printing"},{"portfoliocategory":"Digitization","portfoliocategoryid":"digitization"},{"portfoliocategory":"Android App","portfoliocategoryid":"androidapp"},{"portfoliocategory":"Photography","portfoliocategoryid":"photography"},{"portfoliocategory":"Artwork","portfoliocategoryid":"artwork"}],"fieldSettings":{"autoincrement":1}}

输出应为：

<ul>
<li>printing</li>
<li>digitization</li>
<li>androidapp</li>
<li>photography</li>
<li>artwork</li>
</ul>

感谢。

据我了解你的问题。

$input = '{"fieldValue":[{"portfoliocategory":"Printing","portfoliocategoryid":"printing"},{"portfoliocategory":"Digitization","portfoliocategoryid":"digitization"},{"portfoliocategory":"Android App","portfoliocategoryid":"androidapp"},{"portfoliocategory":"Photography","portfoliocategoryid":"photography"},{"portfoliocategory":"Artwork","portfoliocategoryid":"artwork"}],"fieldSettings":{"autoincrement":1}}';

$output = '<ul>'; // Store the output

$values = json_decode($input); // This will convert to an object

foreach ($values->fieldValue as $val) {
    $output .= '<li>'.$val->portfoliocategoryid.'</li>';
}

$output .= '</ul>';

$ output将为您提供预期的结果。
