使用其他Web站点的数据

<html>
<head>
<title> Stock Quote From NASDAQ </title>
</head>
<body> <?php
$symbol = 'AMZN';
echo "<h1>Stock qupte for ".$symbol."</h1>"; $url = 'http://finance.yahoo.com/d/quotes.csv'.'?s='.$symbol.'&e=.csv&f=fl1d1t1c1ohgv';
if (!($contents = file_get_contents($url))) {
die('Fail to open '. $url);
} list($symbol, $quote, $date, $time) = explode(',', $contents); $date = trim($date, '"');
$time = trim($time, '"'); echo "<p>".$symbol." was last sold at: ".$quote."</p>";
echo "<p>Quote current as of ".$date." at ".$time."</p>"; $baiduURL = "http://baidu.com";
echo "This information retrieved from <br /> ";
echo "<p><a href=\"".$baiduURL."\">".$baiduURL."</a></p>"; ?> </body>
</html>

显示结果:

$host = $url_parse['host']; if (!$ip = gethostbyname($host)) {
echo 'Host for URL does not have valid IP.';
exit;
} echo 'Host is at IP '.$ip.' <br />'; $email = explode('@', $email);
$email_host = $email[1]; if (!dns_get_mx($email_host, $mxhostsarr)) {
echo 'Email address is not at valid host.';
exit;
} echo 'Email is delivered via: ';
foreach($mxhostsarr as $mx) {
echo $mx.'/';
