Skrev en snabb och simpel IMDB-parser i php som jag tänkte dela med mig av.

En snabb titt på hur det ser ut;
http://78.69.194.141/imdb.php

Användning (imdb.php);

<?php
include('cImdbParser.php');
$cImdb = new cImdb();

if(isset($_POST['imdb']) && $_POST['imdb'] != "") {
	if($cImdb->getData("http://www.imdb.com/title/tt1375666/")) {
		echo "Data retrieved..<br />";
	}

	if($cImdb->getMovieTitle() == "") {
		echo "Title does not exist..<br />";
	}
	else {
		echo "Title: " . $cImdb->getMovieTitle() . "<br />";
	}

	if($cImdb->getFirstGenre() == "") {
		echo "First genre does not exist..<br />";
	}
	else {
		echo "First genre: " . $cImdb->getFirstGenre() . "<br />";
	}

	if($cImdb->getSecondGenre() == "") {
		echo "Second genre does not exist..<br />";
	}
	else {
		echo "Second genre: " . $cImdb->getSecondGenre() . "<br />";
	}

	if($cImdb->getYear() == "") {
		echo "Year does not exist..<br />";
	}
	else {
		echo "Year: " . $cImdb->getYear() . "<br />";
	}

	if($cImdb->getMovieRating() == "") {
		echo "Rating does not exist..<br />";
	}
	else {
		echo "Rating: " . $cImdb->getMovieRating() . "<br />";
	}
	echo '<a href="imdb.php">New search</a>';
}
else {
?>
	<form method="post" action="imdb.php">
	IMDB-Url (e.g. http://www.imdb.com/title/tt1375666/):<br />
	<input type="text" name="imdb" />
	<br />
	<input type="submit" value="Retrieve data" />
	</form>
<?php
}
