在数组中输出文本字符串

Question

How do I print the following string in an array in PHP, only selecting the texts in lowercase:

{"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 should be:

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

Thanks.

As I understand your question.

$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 will give you the expected results.
