第一步. 先从文章中把所有a2e895f50458a10b2f286564b51b8302 用正则 抠出来.
代码如下:
$message //文章内容 //正则(这个还不是) $reg = "/<img[^>]*src=\"(http:\/\/(.+)\/(.+)\.(jpg|gif|bmp|bnp))\"/isu"; //把抠出来的 img 地址存放到 $img_array 变量中 preg_match_all($reg, $message, $img_array, preg_pattern_order); //过滤重复的图片 $img_array = array_unique($img_array[1]);
第二步. 把$img_array 数组循环一下. 做图片保存和文章位置替换
代码如下:
foreach ($img_array as $img){ //判断是否是自己网站上的 图片 if('xxx.com' != get_domain($img)){// 如果这个图片不是自己服务器上的 //读取图片文件 $gimg = new getimage(); $gimg->source = $img; $gimg->save_to = './data/temp/'; $file = $gimg->download(); //图片移动到本地 //保存到相册 得到图片保存的位置 $img_path = pic_save($file,0,''); //文本路径替换 $message = str_replace($img, $img_path, $message); } }
....这时候 $message 里面已经图片已经替换为自己服务器本地的地址,并且图片也保存到自己的服务器上.
代码如下:
//下面一个函数 和 类是从网络上找的. //从url中获得域名 function get_domain($url){ $pattern = "/[\w-]+\.(com|net|org|gov|cc|biz|info|cn)(\.(cn|hk))*/"; preg_match($pattern, $url, $matches); if(count($matches) > 0) { return $matches[0]; }else{ $rs = parse_url($url); $main_url = $rs["host"]; if(!strcmp(long2ip(sprintf("%u",ip2long($main_url))),$main_url)) { return $main_url; }else{ $arr = explode(".",$main_url); $count=count($arr); $endarr = array("com","net","org","3322");//com.cn net.cn 等情况 if (in_array($arr[$count-2],$endarr)){ $domain = $arr[$count-3].".".$arr[$count-2].".".$arr[$count-1]; }else{ $domain = $arr[$count-2].".".$arr[$count-1]; } return $domain; }// end if(!strcmp...) }// end if(count...) }// end function // 从远程吧图片载到服务器本地 的 类 class getimage { var $source; var $save_to; var $quality; function download($method = 'curl') { $info = @getimagesize($this->source); $mime = $info['mime']; // what sort of image? $type = substr(strrchr($mime, '/'), 1); switch ($type){ case 'jpeg': $image_create_func = 'imagecreatefromjpeg'; $image_save_func = 'imagejpeg'; $new_image_ext = 'jpg'; // best quality: 100 $quality = isset($this->quality) ? $this->quality : 100; break; case 'png': $image_create_func = 'imagecreatefrompng'; $image_save_func = 'imagepng'; $new_image_ext = 'png'; // compression level: from 0 (no compression) to 9 $quality = isset($this->quality) ? $this->quality : 0; break; case 'bmp': $image_create_func = 'imagecreatefrombmp'; $image_save_func = 'imagebmp'; $new_image_ext = 'bmp'; break; case 'gif': $image_create_func = 'imagecreatefromgif'; $image_save_func = 'imagegif'; $new_image_ext = 'gif'; break; case 'vnd.wap.wbmp': $image_create_func = 'imagecreatefromwbmp'; $image_save_func = 'imagewbmp'; $new_image_ext = 'bmp'; break; case 'xbm': $image_create_func = 'imagecreatefromxbm'; $image_save_func = 'imagexbm'; $new_image_ext = 'xbm'; break; default: $image_create_func = 'imagecreatefromjpeg'; $image_save_func = 'imagejpeg'; $new_image_ext = 'jpg'; } if(isset($this->set_extension)){ $ext = strrchr($this->source, "."); $strlen = strlen($ext); $new_name = basename(substr($this->source, 0, -$strlen)).'.'.$new_image_ext; }else{ $new_name = basename($this->source); } $save_to = $this->save_to."/blog_insert_temp_".time().mt_rand(1,99).".".$new_image_ext; //输出对象 组成跟$_file变量一样 得到后自己和平常图片上传处理一样了 $img_info['name'] = basename($this->source); $img_info['type'] = $mime; $img_info['size'] = 1000; $img_info['tmp_name'] = $save_to; $img_info['error'] = 0; if($method == 'curl'){ $save_image = $this->loadimagecurl($save_to); }elseif($method == 'gd'){ $img = $image_create_func($this->source); if(isset($quality)){ $save_image = $image_save_func($img, $save_to, $quality); }else{ $save_image = $image_save_func($img, $save_to); } } return $img_info; } function loadimagecurl($save_to){ $ch = curl_init($this->source); $fp = fopen($save_to, "wb"); // set url and other appropriate options $options = array(curlopt_file => $fp, curlopt_header => 0, curlopt_followlocation => 1, curlopt_timeout => 60); // 1 minute timeout (should be enough) curl_setopt_array($ch, $options); curl_exec($ch); curl_close($ch); fclose($fp); } }
以上就是用php实现远程图片采集到本地的方法的详细内容。
