Simple XML from string - what's missing?
I'm driving myself crazy here, I'm almost positive I am at least on the right track.
I'm just trying to parse a response that I am getting from an API that comes back in XML. I really only need to print the "Lyric" index.
Anywho, here is the code:
<?php
$artist = $_GET['artist'];
$song = $_GET['song'];
if(isset($_GET['artist']) && isset($_GET['song']))
{
$result = get_lyrics($artist, $song);
} else {
$result = "";
}
function get_lyrics($artist, $song)
{
$postURL = "http://api.chartlyrics.com/apiv1.asmx/SearchLyricDirect?artist=".urlencode($artist)."&song=".urlencode($song);
echo $postURL;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $postURL);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$re开发者_运维问答sult = curl_exec($ch);
curl_close($ch);
return $result;
}
?>
<html>
<head><title>Lyric Search</title></head>
<form action="<?=$_SERVER['PHP_SELF']?>" method="get">
<p>Artist<input type="input" name="artist" /></p>
<p>Song<input type="input" name="song" /></p>
<input type="submit" value="submit" />
</form>
<div id="results">
<?php
$xml = simplexml_load_string($result);
foreach($xml->GetLyricResult as $lyric)
{
echo $lyric->Lyric;
}
?>
</div>
</html>
And here is the xml....
http://api.chartlyrics.com/apiv1.asmx/SearchLyricDirect?artist=lady+gaga&song=poker+face
You don't need to use foreach because there's only one lyric.
you just need:
<div id="results">
<?php
$xml = simplexml_load_string($result);
echo $xml->Lyric[0];
?>
</div>
Try:
<html>
<head><title>Lyric Search</title></head>
<form action="<?=$_SERVER['PHP_SELF']?>" method="get">
<p>Artist<input type="input" name="artist" /></p>
<p>Song<input type="input" name="song" /></p>
<input type="submit" value="submit" />
</form>
<div id="results">
<?php
if(isset($_GET['artist']) && isset($_GET['song'])){
$result = get_lyrics($_GET['artist'],$_GET['song']);
$xml = simplexml_load_string($result);
echo "<pre>";
//print_r($xml);
echo $xml->Lyric;
echo "</pre>";
}
function get_lyrics($artist, $song)
{
$postURL = "http://api.chartlyrics.com/apiv1.asmx/SearchLyricDirect?artist=".urlencode($artist)."&song=".urlencode($song);
echo $postURL;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $postURL);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
?>
</div>
</html>
