//获取远程图片大小
$ch = curl_init($img_path['img']);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$rs = curl_exec($ch);
$regex = '/Content-Length: ([0-9]*)/';
preg_match($regex, $rs, $matches);

if(empty($matches[1]) || $matches[1]==0){
    return false;
}

$remote_size = $matches[1];

//获取远程图片大小

$ch = curl_init($img_path['img']);

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_NOBODY, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$rs = curl_exec($ch);

$regex = '/Content-Length: ([0-9]*)/';

preg_match($regex, $rs, $matches);

if(empty($matches[1]) || $matches[1]==0){

return false;

}

$remote_size = $matches[1];
