PHP 取得網頁原始碼、網頁標題的實作程式碼

$lines = file('http://bbs.it-home.org/');
foreach ($lines as $line_num => $line) {
echo "Line {$line_num} : " . htmlspecialchars($line) . "n";
}
?>

2，获取网页的标题：

$url = 'http://bbs.it-home.org';
$lines_array = file($url);
echo $lines_array;
echo "";
$lines_string = implode('', $lines_array);
eregi("(.*)", $lines_string, $head);
echo "head:".$head;
echo "";
print_r($head);
echo "";
echo "title:".$head[1];
?>
