Creating a single var for a foreach loop - php

Question

i am trying to get my list of tags but using a foreach so that i can put each tag into a list element.
What i used to do was:
$tagsArray = "these,are,some,tags"
// Explode the tags
$tagsArray = explode(",",$tags);
<ul>
<?php
// Create a list for the tags
foreach($tagsArray as $var)
{
echo "<li>$var</li>";
}
?>
</ul>
However, i now need to display this array inside an echo as well as other items.
Example:
<?php
echo "
<div id='editInfomation'>
<div id='Title'>This is a title</div>
<div id='tags'>
<ul>$tags</ul>
</div>
</div>
";
?>
How should i create a $tags variable that will contain all the exploded tags but in list element tags? Thanks.

Answer 1

This is what you need.
$tagsArray = "these,are,some,tags";
$tags = "<li>".implode("</li>,<li>",explode(",",$tagsArray ))."</li>";
And you simply print
<?php
echo "
<div id='editInfomation'>
<div id='Title'>This is a title</div>
<div id='tags'>
<ul>$tags</ul>
</div>
</div>
";
?>

I'm not 100% sure on what you're asking, but:

You can push each element into an array, formatted:
$output = array();
foreach($tagsArray as $var) {
$output[] = "<li>$var</li>";
}
... then:
echo "<ul>" . implode($output) . "</ul>";
