Echo array with string as separator

Question

I have the following code in PHP, which searches a file for lines containing a string:

<?php
echo "Results for: ";
echo ($_POST['query']);
echo "<br><br>";
$file = 'completed.db';
$searchfor = ($_POST['query']);
header('Content-Type: text/plain');
$contents = file_get_contents($file);
$pattern = preg_quote($searchfor, '/');
$pattern = "/^.*$pattern.*\$/m";
if(preg_match_all($pattern, $contents, $matches)){
   echo "Found matches:\n";
   echo implode("\n", $matches[0]);
}
else{
   echo "No matches found";
}
?>

In the line, echo implode("\n", $matches[0]); in echos an array, separated by spaces. If I wanted to separate the items by a different string, say $entry = '<br>', how would you do it?

For example, if $matches was

one
two
three

Then, the command should echo:

one<br>two<br>three<br>

Just add the break tag to the string

echo implode("\n<br>", $matches[0]);

And one more to trail since implode only goes between.

echo "<br>";

The following code simply uses implode with a different first argument, bu also adds the separator to the end (as per specification)

$entry = '<br>';
echo implode($entry, $matches[0]).$entry;

Could you explain how your answer addresses the problem(s) from the question? Code-only answers are not very useful, especially for further readers that stumble upon this post. Thanks!
