Salve! Ho un problema con una pagina... viene caricata correttamente circa 4 volte su 10. Qui potete trovare un esempio, ovviamente se vedete la pagina bianca, ricaricate finché non compare qualcosa.

Questo è il codice sorgente della pagina in questione:
Codice PHP:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>


<HEAD>
<?php require_once("twitterreader.php"); ?>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type>
<style type="text/css">

<!--

body {background:#fff;margin:0;padding:0;font-size:75%;font-family: lucida Grande, Helvetica, Arial, sans-serif;color:#333;}

ul.twitter {margin:0;padding:0;}

ul.twitter li {list-style:none;padding:10px 0px;border-bottom:1px solid #e7e7e7;}

ul.twitter a {color:#777;text-decoration:none;}

ul.twitter a:hover {color:#333;text-decoration:underline;}

small {color:#888;}

-->

</style>
</HEAD>
<BODY>


<?php



// Run the function, with your twitter username and number of tweets as arguments
$mytweets = fetch_tweets('C__Lac', 4);

echo '<ul class="twitter">';
foreach ($mytweets as $k => $v) {
echo '<li>';
echo '<span class="twitter">' .$v['desc']. '</span>';
echo '<br>';
echo '<small><span class="twitter">' .$v['date']. '</span></small>';
echo '</li>';
}
echo '</ul>';
?>

</BODY></HTML>
E questa è la pagina che viene richiamata nella prima:

Codice PHP:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD>
<BODY>
<?php

function fetch_tweets($username, $maxtweets) {
//Using simplexml to load URL
$tweets = simplexml_load_file("http://twitter.com/statuses/user_timeline/" . $username . ".rss");

$tweet_array = array(); //Initialize empty array to store tweets
foreach ( $tweets->channel->item as $tweet ) {
//Loop to limitate nr of tweets.
if ($maxtweets == 0) {
break;
} else {
$twit = $tweet->description; //Fetch the tweet itself

//Remove the preceding 'username: '
$twit = substr(strstr($twit, ': '), 2, strlen($twit));

// Convert URLs into hyperlinks
$twit = preg_replace("/(http:\/\/)(.*?)\/([\w\.\/\&\=\?\-\,\:\;\#\_\~\%\+]*)/", "<a href=\"\\0\">\\0</a>", $twit);

// Convert usernames (@) into links
$twit = preg_replace("(@([a-zA-Z0-9\_]+))", "<a href=\"http://www.twitter.com/\\1\">\\0</a>", $twit);

// Convert hash tags (#) to links
$twit = preg_replace('/(^|\s)#(\w+)/', '\1<a href="http://search.twitter.com/search?q=%23\2">#\2</a>', $twit);

//Specifically for non-English tweets, converts UTF-8 into ISO-8859-1
$twit = iconv("UTF-8", "ISO-8859-1//TRANSLIT", $twit);

//Get the date it was posted
$pubdate = strtotime($tweet->pubDate);
$propertime = gmdate('F jS Y, H:i', $pubdate); //Customize this to your liking

//Store tweet and time into the array
$tweet_item = array(
'desc' => $twit,
'date' => $propertime,
);
array_push($tweet_array, $tweet_item);

$maxtweets--;
}
}
//Return array
return $tweet_array;
}
?>

Ho davvero scarse conoscenze di programmazione in PHP, lo script non l'ho creato io, ma l'ho trovato su internet.
