php curl的几段小应用
php 的CURL是不错的功能,下面收藏几段不错的片段
1 测试网站是否运行正常
<? if (isDomainAvailible('http://gz.itownet.cn')) { echo "Up and running!"; } else { echo "Woops, nothing found there."; } //returns true, if domain is availible, false if not function isDomainAvailible($domain) { //check, if a valid url is provided if(!filter_var($domain, FILTER_VALIDATE_URL)) { return false; } //initialize curl $curlInit = curl_init($domain); curl_setopt($curlInit,CURLOPT_CONNECTTIMEOUT,10); curl_setopt($curlInit,CURLOPT_HEADER,true); curl_setopt($curlInit,CURLOPT_NOBODY,true); curl_setopt($curlIn！本文来源gaodai.ma#com搞#代!码(网搞gaodaima代码it,CURLOPT_RETURNTRANSFER,true); //get answer $response = curl_exec($curlInit); curl_close($curlInit); if ($response) return true; return false; }?>
2 可以代替file_gecontents的操作
function file_get_contents_curl($url) { $ch = curl_init(); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //Set curl to return the data instead of printing it to the browser. curl_setopt($ch, CURLOPT_URL, $url); $data = curl_exec($ch); curl_close($ch); return $data;}
3 保存某个网站下的所有图片
function getImages($html) { $matches = array(); $regex = '~http://somedomain.com/images/(.*?)\.jpg~i'; preg_match_all($regex, $html, $matches); foreach ($matches[1] as $img) { saveImg($img); }}function saveImg($name) { $url = 'http://somedomain.com/images/'.$name.'.jpg'; $data = get_data($url); file_put_contents('photos/'.$name.'.jpg', $data);}$i = 1;$l = 101;while ($i < $l) { $html = get_data('http://somedomain.com/id/'.$i.'/'); getImages($html); $i += 1;}
4 FTP应用
// open a file pointer$file = fopen("/path/to/file", "r");// the url contains most of the info needed$url = "ftp://username:[email protected]:21/path/to/new/file";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);// upload related optionscurl_setopt($ch, CURLOPT_UPLOAD, 1);curl_setopt($ch, CURLOPT_INFILE, $fp);curl_setopt($ch, CURLOPT_INFILESIZE, filesize("/path/to/file"));// set for ASCII mode (e.g. text files)curl_setopt($ch, CURLOPT_FTPASCII, 1);$output = curl_exec($ch);curl_close($ch);
