Print an array of pipe-delimited values as HTML list item tags

Data comes from Wordpress metabox in a form of single long array.

The data that I insert in metabox looks like this:

Rhine Riesling1|0,75 l|9,50 &euro

Rhine Riesling2|0,75 l|9,50 &euro

Rhine Riesling3|0,75 l|9,50 &euro

Rhine Riesling4|0,75 l|9,50 &euro

Final output should look like this:

<ul class="listmenuitems" id="listingmenu_1">
    <li><p>Rhine Riesling1 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling2 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling3 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling4 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
</ul>

How would I cut the array values into pieces considering the separator | and then loop through it to create a correctly formatted <li><p>?

I'm reading about PHP's explode() at the moment.

Using vprintf() will allow you to cleanly declare the HTML template string and immediately consume the returned array from explode().

Code: (Demo)

$array = [
    'Rhine Riesling1|0,75 l|9,50 &euro',
    'Rhine Riesling2|0,75 l|9,50 &euro',
    'Rhine Riesling3|0,75 l|9,50 &euro',
    'Rhine Riesling4|0,75 l|9,50 &euro',
];

echo '<ul class="listmenuitems" id="listingmenu_1">' . "\n";
    foreach ($array as $psv) { // pipe-separated values
        vprintf(
            "\t" . '<li><p>%s <span>%s</span></p> <span class="listmenuprice">%s;</span></li>' . "\n",
            explode('|', $psv)
        );
    }
echo '</ul>';

Output:

<ul class="listmenuitems" id="listingmenu_1">
    <li><p>Rhine Riesling1 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling2 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling3 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling4 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
</ul>

Suppose your array is 

$metabox;

Then 

echo '<ul class="listmenuitems" id="listingmenu_1">';
foreach($metabox as $val)
{
$petabox=explode("|",$val);
echo '<li><p>'.$petabox[0].'<span>'.$petabox[1].'</span></p> <span class="listmenuprice">'.$petabox[2].'</span></li>';
}
echo '</ul>';

You can use the PHP explode command. http://php.net/manual/en/function.explode.php

Loop through your array, on each entry call: explode("|", $entry); then you can print out what you want like so:

$input_arr[];
echo '<ul class="listmenuitems" id="listingmenu_1">';
for($i=0;i<sizeof($input_arr);$i++) {

    $e = explode("|",$input_arr[$i]);
    echo "<li><p>" . $e[0] . "<span>" . $e[1] . "</span></p> <span class=\"listmenuprice\">" . $e[2] . "</span></li>";

}

Note there is on error checking and it is assumed that you have a complete and well formed array input.

Updated to add foreach ;) And if the foreach loop is your fancy...

$input_arr[];
echo '<ul class="listmenuitems" id="listingmenu_1">';
foreach($input_arr as $i) {

    $e = explode("|",$i);
    echo "<li><p>" . $e[0] . "<span>" . $e[1] . "</span></p> <span class=\"listmenuprice\">" . $e[2] . "</span></li>";

}

list($name,$content,$price) = explode("|",$line) 
printf('<li><p>%s<span>%s</span></p> <span class="listmenuprice">%s</span></li>',$name,$content,$price)
