Output All Currency Values using PHP

I am trying to utilize the Bitcoin Charts API to display bitcoin value in all currencies as list items.

Currently I am repeating this PHP snippet in each list item:

<li class="myClass">
    <?php
        foreach(json_decode(file_get_contents("http://api.bitcoincharts.com/v1/markets.json")) as $item)
            if($item->symbol == 'localbtcPLN') break;
            printf("\t%s\nPLN", $item->avg);
    ?>
</li>

How can I simplify this so that the code is only calling the JSON file once?

Thanks for your help.

As per Vishal's assistance, I tried this:

 <?php $all_data = json_decode(file_get_contents("http://api.bitcoincharts.com/v1/markets.json"),true);
    foreach ($all_data as $data)
        { 
        ?><li class="pure-menu-item pure-menu-disabled">
        <?php
           echo $data['ask'];//use the keyname to get the value
           echo ' ';
           echo $data['currency'];
        ?>
        </li>
 <?php
     }
 ?>

However, it is outputting too much data, including empty values.

Using what I've learned from Florian and Vishal, I have attempted the following snippet, which outputted the data perfectly with the caveat of some duplicated currencies.

<?php $all_data = json_decode(file_get_contents("http://api.bitcoincharts.com/v1/markets.json"),true);
                foreach ($all_data as $data)
                { 
                 if(trim($data['avg']) != "")//check if value not empty
                 {
                  ?><li class="pure-menu-item pure-menu-disabled">
                    <?php
                        echo $data['avg']; //use the keyname to get the value
                        echo ' ';
                        echo $data['currency'];
                    ?>
                    </li>
                 <?php
                 }
                 }
              ?>

you can run a foreach loop

    <ol>
     <?php $all_data = json_decode(file_get_contents("http://api.bitcoincharts.com/v1/markets.json"),true);
    foreach ($all_data as $data)
    { 
     if(trim($data['currency']) != "")//check if value not empty
     {
      ?><li>
        <?php echo $data['bid'];//use the keyname to get the value ?>
        </li>
     <?php
     }
     }
  ?>
    </ol>

I think you want to show values in a certain order.

First, store the result of json_decode() in an array like @Vishal Wadhawan said.

$all_data = json_decode(file_get_contents("http://api.bitcoincharts.com/v1/markets.json"),true);

Next, make a new array where you will store only symbol and avg: 

$myvalues = array();
foreach ($all_data as $data)
{
    $myvalues[$data['symbol']] = $data['avg'];
}

After that, you can use $myvalues to display avg like that:

<li class="myClass">    
    <?php echo $myvalues['localbtcPLN'] . ' PLN'; ?>
</li>

You can also store the 'currency' value:

$myvalues[$data['symbol']] = array(
                                    'avg' => $data['avg'],
                                    'currency' => $data['currency'],
);

And access it with:

<li class="myClass">    
    <?php echo $myvalues['localbtcPLN']['avg'] . ' ' . $myvalues['localbtcPLN']['currency']; ?>
</li>
