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);

 $img_array = array_unique($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);

   return false;}

//用法如下：
 
$str ='fasfsdafsa';
echo get_remote($str,'图片');
