I have a page called index.php which has some content on it, but the title is set from another server that generates a text file called cache_currentsongcallapi.txt
Contents of 'cache_currentsongapi.txt':
<tracks>
<radioname>Mick&apos;s Music Station</radioname>
<rank>0</rank>
<isradionomy>1</isradionomy>
<radurl>http://www.radionomy.com/mick-smusicstation</radurl>
<track>
<uniqueid>2722440231</uniqueid>
<title>Hello</title>
<artists>Adele</artists>
<starttime>2015-11-23 21:05:02.35</starttime>
<playduration>293023</playduration>
<current>1</current>
<callmeback>217256</callmeback>
</track>
</tracks>
Is there any way that I can take ONLY the title from the text file and display it in the index page?
NOTE:
This method cannot include editing the text file as it is overwritten by the server.

Answer 1

This appears like valid XML. Never, never read XML using regular expressions. You'll hear this a lot, and for good reasons.
I'd start by reading the string as XML:
$xml = new SimpleXMLElement($string);
$result = $xml->xpath('/tracks/track/title');
Your mileage may vary, but basically you can do a lot starting from here. I'd suggest reading a bit more on DOMXPath and SimpleXMLElement.

Here's a full version including the reading of the actual file since you seem to need help there too, but please mark Victor's as the answer.
$filePath = "file.txt";
$handle = fopen($filePath, "r");
$fileContents = fread($handle, filesize($filePath));
$xml = new SimpleXMLElement($fileContents);
$title = $xml->xpath("/tracks/track/title");
echo($title[0]);
Where "file.txt" is the path to the file.
