PHP RegEx replace

Question

I'm trying to write a PHP Script that replaces auto-generated Content from a WordPress Plugin. The Plugin isn't able to provide a WYSIWYG Editor for special fields but it can recognize new lines. My Output would look like this:

Some Text that has to
go over a few
lines of code
because it's actually supposed to be a list

when the client writes inside these field all lines get <br> tags at the end, so I tried to find and replace them with </li> tags as well as adding a <li> in front of every new line. My PHP Script looks like this:

 $text = types_render_field("field-name");

 $pattern = array();
 $pattern[0] = "/br/"; // br tags
 $pattern[1] = "/\n/"; // new lines
 $replacements = array();
 $replacements[0] = "/li"; // replacement for <br>
 $replacements[1] = "<li>"; // insert into every new line (\n)

 echo "<ul>"; // wrapping the <li>'s
 echo preg_replace($pattern, $replacements, $text);
 echo "</ul>";

It's actually working so far but the first line get's no <li> in front of it so my question is: How do I get a <li> in front of the first line?

Keep it simple. Instead of

echo "<ul>"; // wrapping the <li>'s

Use:

echo "<ul><li>"; // wrapping the <li>'s

OR else:

Instead of:

$pattern[1] = "/\n/"; // new lines

Use:

$pattern[1] = "/^|\n/"; // new lines OR start

Damn... :( It's always the same, I'm thinking way too complex. Thank you!

How about:

$pattern = "/(.+?)(<br>|$)/i"; // capture the text before the br tag
$replacement = "<li>$1</li>"; 
echo "<ul>"; 
echo preg_replace($pattern, $replacement, $text);
echo "</ul>";

Keep in mind that the text at the end of the string will almost certainly not be followed by a <br> tag.

You're right! I didn't thought about it. But with anubhava solution I can add "echo "</li></ul>" so the last one gets closed, too. Thanks for pointing me on that.
