?>二、从网页中提取关键字 $meta = get_meta_tags('http://www.emoticode.net/');
$keywords = $meta['keywords'];
// Split keywords $keywords = explode(',', $keywords );
// Trim them $keywords = array_map( 'trim', $keywords );
// Remove empty values $keywords = array_filter( $keywords );
print_r( $keywords );三、查找页面上的所有链接 $html = file_get_contents('http://www.example.com');
$dom = new DOMDocument();
@$dom->loadHTML($html);
// grab all the on the page $xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");
for ($i = 0; $i < $hrefs->length; $i++) {
$href = $hrefs->item($i);
$url = $href->getAttribute('href');
echo $url.'<br />';
}四、自动转换URL,跳转至超链接 function _make_url_clickable_cb($matches) {
$ret = '';
$url = $matches[2];
if ( empty($url) )
return $matches[0];
// removed trailing [.,;:] from URL if ( in_array(substr($url, -1), array('.', ',', ';', ':')) === true ) {
$ret = substr($url, -1);
$url = substr($url, 0, strlen($url)-1);
}
return $matches[1] . "<a href=\"$url\" rel=\"nofollow\">$url</a>" . $ret;
}
function _make_web_ftp_clickable_cb($matches) {
$ret = '';
$dest = $matches[2];
$dest = 'http://' . $dest;
if ( empty($dest) )
return $matches[0];
// removed trailing [,;:] from URL if ( in_array(substr($dest, -1), array('.', ',', ';', ':')) === true ) {
$ret = substr($dest, -1);
$dest = substr($dest, 0, strlen($dest)-1);
}
return $matches[1] . "<a href=\"$dest\" rel=\"nofollow\">$dest</a>" . $ret;
}
function _make_email_clickable_cb($matches) {
$email = $matches[2] . '@' . $matches[3];
return $matches[1] . "<a href=\"mailto:$email\">$email</a>";
}
function make_clickable($ret) {
$ret = ' ' . $ret;
// in testing, using arrays here was found to be faster $ret = preg_replace_callback('#([\s>])([\w]+?://[\w\\x80-\\xff\#$%&~/.\-;:=,?@\[\]+]*)#is', '_make_url_clickable_cb', $ret);
$ret = preg_replace_callback('#([\s>])((www|ftp)\.[\w\\x80-\\xff\#$%&~/.\-;:=,?@\[\]+]*)#is', '_make_web_ftp_clickable_cb', $ret);
$ret = preg_replace_callback('#([\s>])([.0-9a-z_+-]+)@(([0-9a-z-]+\.)+[0-9a-z]{2,})#i', '_make_email_clickable_cb', $ret);
// this one is not in an array because we need it to run last, for cleanup of accidental links within links $ret = preg_replace("#(<a( [^>]+?>|>))<a [^>]+?>([^>]+?)</a></a>#i", "1ドル3ドル</a>", $ret);
$ret = trim($ret);
return $ret;
}五、创建数据URL function data_uri($file, $mime) {
$contents=file_get_contents($file);
$base64=base64_encode($contents);
echo "data:$mime;base64,$base64";
}六、从服务器上下载&保存一个远程图片 $image = file_get_contents('http://www.url.com/image.jpg');
file_put_contents('/images/image.jpg', $image); 七、移除Remove Microsoft Word HTML Tag function cleanHTML($html) {
/// <summary> /// Removes all FONT and SPAN tags, and all Class and Style attributes. /// Designed to get rid of non-standard Microsoft Word HTML tags. /// </summary> // start by completely removing all unwanted tags
$html = ereg_replace("<(/)?(font|span|del|ins)[^>]*>","",$html);
// then run another pass over the html (twice), removing unwanted attributes
$html = ereg_replace("<([^>]*)(class|lang|style|size|face)=("[^"]*"|'[^']*'|[^>]+)([^>]*)>","<1円>",$html);
$html = ereg_replace("<([^>]*)(class|lang|style|size|face)=("[^"]*"|'[^']*'|[^>]+)([^>]*)>","<1円>",$html);
return $html
}八、检测浏览器语言 function get_client_language($availableLanguages, $default='en'){
if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
$langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']);
foreach ($langs as $value){
$choice=substr($value,0,2);
if(in_array($choice, $availableLanguages)){
return $choice;
}
}
}
return $default;
}
