Extracting data from PHP array

Question

I am using Caldera forms to store data on my WordPress site. When I save data for multiple choices (checkboxes) I get an array of data which is similar to following;

{"opt905217":"Option 1","opt2347462":"Option 2","opt905265":"Option 3","opt906845":"Option 4",}

How can I achiveve the following;

<ul>
<li>Option 1</li>
<li>Option 2</li>
<li>Option 3</li>
<li>Option 4</li>
</ul>

I tried using explode. But the problem is I have to skip the option IDs (e.g. opt2347462)

How can I get a list of only the option values?

u converting array to string so you must use implode function — Vijaya Vignesh Kumar

foreach ($array as $key => $value) {
    echo "<li>".$value."</li>"
}

And if your array is a json, first json_decode($array, true)

As I see that you have JSON data.

$json = '{"opt905217":"Option 1","opt2347462":"Option 2","opt905265":"Option 3","opt906845":"Option 4",}';

$obj = json_decode($json);
print $obj->{'opt905217'}; // Option 1

Few Points to remember:

json_decode requires the string to be a valid json else it will return NULL.
In the event of a failure to decode, json_last_error() can be used to determine the exact nature of the error.
Make sure you pass in utf8 content, or json_decode may error out and just return a NULL value.

<?php
$abc = '{"opt905217":"Option 1","opt2347462":"Option 2","opt905265":"Option 3","opt906845":"Option 4"}';
$newarray = json_decode($abc,true); ?>
<ul>
<?php foreach($newarray as $key => $value){ ?>
    <li><?php echo $value; ?></li>
<?php }?>


</ul>
