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);

}
}
