站长图库向大家介绍了PHP远程采集,正则图片案例等相关知识,希望对您有所帮助
很多时候我们需要采集其他网站的图片到本地，主要是为了稳定性，以及方便管理。下面提供一段代码。大家参考！
<?php//图片接口地址(这里还是要拿小诗梦开刀)$url = 'https://******/';// 图片存放文件夹$path = 'images/';$str = file_get_contents($url);preg_match_all('/<img alt="\/\/(.*?)" src="\/\/(.*?)" \/>/',$str,$img);$imgUrl = 'https://'.$img[2][0];if(!$imgUrl){exit(json_encode(array('error'=>'采集失败')));}$filename = basename($imgUrl);$filenames = $path.$filename;if(file_exists($filenames)){ //文件已经存在 echo json_encode(array('url'=>$imgUrl,'filename'=>$filenames,'state'=>'202'));}else{ if(download($imgUrl,$path)){ //采集成功 echo json_encode(array('url'=>$imgUrl,'filename'=>$filenames,'state'=>'200')); }else{ //采集失败 echo json_encode(array('url'=>$imgUrl,'filename'=>$filenames,'state'=>'201')); }}function download($url, $path = 'images/'){ //远程下载保存 if (! file_exists ( $path )) { mkdir ( "$path", 0777, true ); } $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,2); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30); $file = curl_exec($ch); curl_close($ch); $filename = pathinfo($url, PATHINFO_BASENAME); $resource = fopen($path . $filename, 'a'); fwrite($resource, $file); fclose($resource); return true;}?>
