php采集内容中带有图片地址的远程图片并保存的方法 本文实例讲述了php采集内容中带有图片地址的远程图片并保存的方法。分享给大家供大家参考。具体实现方法如下: 复制代码 代码如下:function my_file_get_contents($url, $timeout=30) { if ( function_exists('curl_init') ) { $ch = curl_init(); curl_setopt ($ch, curlopt_url, $url); curl_setopt ($ch, curlopt_returntransfer, 1); curl_setopt ($ch, curlopt_connecttimeout, $timeout); $file_contents = curl_exec($ch); curl_close($ch); } else if ( ini_get('allow_url_fopen') == 1 || strtolower(ini_get('allow_url_fopen')) == 'on' ) { $file_contents = @file_get_contents($url); } else { $file_contents = ''; } return $file_contents; } 复制代码 代码如下:function get_remote($body,$title){ $img_array = array(); $img_path = realpath("../../../upfile/news/").'/'.date("y/m/d/"); //采集远程图片保存地址 //die($img_path); $img_rpath='/upfile/news/'.date("y/m/d/"); //设置访问地址 $body = stripslashes(strtolower($body)); preg_match_all("/(src|src)=["|'| ]{0,}(http://(.*).(gif|jpg|jpeg|png))/isu",$body,$img_array); $img_array = array_unique($img_array[2]); foreach ($img_array as $key => $value) { $get_file = my_file_get_contents($value,60); $filetime = time(); $filename = date("ymdhis",$filetime).rand(1,999).'.'.substr($value,-3,3); if(emptyempty($get_file)){ @sleep(10); $get_file = my_file_get_contents($value,30); if(emptyempty($get_file)){ $body = preg_replace("/".addcslashes($value,"/")."/isu", '/notfound.jpg', $body); continue; } } if(!emptyempty($get_file) ){ if( mkdirs($img_path) ) { $fp = fopen($img_path.$filename,"w"); if(fwrite($fp,$get_file)){ $body = preg_replace("/".addcslashes($value,"/")."/isu", $img_rpath.$filename, $body); } fclose($fp); @sleep(6); } } } $body =str_replace("
