load text file list into <option> tags

问题

Im working on a PHP project that involves selecting a song, hitting the submit button and then having the PHP loading the song player to the correct option.

For the song selection I want to load these options from a txt file with the following formatting:

<br />
<code>All For Love <br /> Break Free <br />Come to the River <br />For You Nam    </code>

---

Which I want to be processed to end up like this:

<br /> <code>
< option value="All For Love"> All For Love< /option> <br /> 
< option value="Break Free">Break Free< /option> <br /> 
< option value="Come to the River">Come To The River< /option> <br /> 
< option value="For Your Name">For Your Name< /option> <br /> 

---

How would I go about achieving this? project so far
