I copied the code from this site exactly: http://davidwalsh.name/web-service-php-mysql-xml-json as follows,
/* require the user as the parameter */
if(isset($_GET['user']) && intval($_GET['user'])) {
/* soak in the passed variable or set our own */
$number_of_posts = isset($_GET['num']) ? intval($_GET['num']) : 10; //10 is the default
$format = strtolower($_GET['format']) == 'json' ? 'json' : 'xml'; //xml is the default
$user_id = intval($_GET['user']); //no default
/* connect to the
db */
$link = mysql_connect('localhost','username','password') or die('Cannot connect to the
DB');
mysql_select_db('db_name',$link) or die('Cannot
select the
DB');
/* grab the posts from the
db */
$query = "
SELECT post_title, guid FROM wp_posts WHERE post_author = $user_id AND post_status = 'publish' ORDER BY ID DESC LIMIT $number_of_posts";
$result = mysql_query($query,$link) or die('Errant query: '.$query);
/* create one master array of the records */
$posts = array();
if(mysql_num_rows($result)) {
while($post = mysql_fetch_assoc($result)) {
$posts[] = array('post'=>$post);
}
}
/* output in necessary format */
if($format == 'json') {
header('Content-type: application/json');
echo json_encode(array('posts'=>$posts));
}
else {
header('Content-type: text/xml');
echo '<posts>';
foreach($posts as $index => $post) {
if(is_array($post)) {
foreach($post as $key => $value) {
echo '<',$key,'>';
if(is_array($value)) {
foreach($value as $tag => $val) {
echo '<',$tag,'>',htmlentities($val),'</',$tag,'>';
}
}
echo '</',$key,'>';
}
}
}
echo '</posts>';
}
/* disconnect from the
db */
@mysql_close($link);
}
And the php doesn't execute, it just displays as plain text. What's the dealio? The host supports PHP, I use it to run a Wordpress blog and other things.
