php采集内容中带有图片地址的远程图片并保存的方法_php技巧

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：

function my_file_get_contents($url, $timeout=30) { <br /> if ( function_exists('curl_init') )  <br /> { <br />  $ch = curl_init(); <br />  curl_setopt ($ch, curlopt_url, $url); <br />  curl_setopt ($ch, curlopt_returntransfer, 1); <br />  curl_setopt ($ch, curlopt_connecttimeout, $timeout); <br />  $file_contents = curl_exec($ch); <br />  curl_close($ch); <br /> }  <br /> else if ( ini_get('allow_url_fopen') == 1 || strtolower(ini_get('allow_url_fopen')) == 'on' )    <br /> { <br />  $file_contents = @file_get_contents($url); <br /> }  <br /> else  <br /> { <br />  $file_contents = ''; <br /> } <br /> return $file_contents; <br />}

function get_remote($body,$title){ <br /> <br /> $img_array = array();  <br /> $img_path = realpath("../../../upfile/news/").'/'.date("y/m/d/"); //采集远程图片保存地址 <br /> //die($img_path); <br /> $img_rpath='/upfile/news/'.date("y/m/d/");  //设置访问地址 <br /> $body = stripslashes(strtolower($body));  <br /> preg_match_all("/(src|src)=["|'| ]{0,}(http://(.*).(gif|jpg|jpeg|png))/isu",$body,$img_array);  <br /> $img_array = array_unique($img_array[2]);  <br /> foreach ($img_array as $key => $value) {  <br />  $get_file = my_file_get_contents($value,60); <br />  $f<mark style="color:transparent">来4源gaodaimacom搞#代%码*网</mark><code>搞代gaodaima码</code>iletime = time();    <br />  $filename = date("ymdhis",$filetime).rand(1,999).'.'.substr($value,-3,3);  <br />  if(emptyempty($get_file)){ <br />   @sleep(10); <br />   $get_file = my_file_get_contents($value,30); <br />   if(emptyempty($get_file)){ <br />    $body = preg_replace("/".addcslashes($value,"/")."/isu", '/notfound.jpg', $body); <br />    continue; <br />    } <br />  } <br />  if(!emptyempty($get_file) ){ <br />   if( mkdirs($img_path) ) <br />   { <br />    $fp = fopen($img_path.$filename,"w"); <br />    if(fwrite($fp,$get_file)){          <br />     $body = preg_replace("/".addcslashes($value,"/")."/isu", $img_rpath.$filename, $body);  <br />    } <br />    fclose($fp); <br />    @sleep(6); <br />   }    <br />  }     <br />  <br /> } <br /> $body =str_replace(" return $body;<br />  <br />} <br /> <br />function mkdirs($dir) <br />{ <br /> if(!is_dir($dir)){ <br />  if(!mkdirs(dirname($dir))){ <br />   return false;} <br />  if(!mkdir($dir,0777)){ <br />   return false;} <br /> } <br /> return true; <br />} <br />//用法如下：<br /> <br />$str ='fasfsdafsa'; <br />echo get_remote($str,'图片');

希望本文所述对大家的php程序设计有所帮助。
