1.获取远程文件大小及信息的函数
function getFileSize($url){ $url = parse_url($url); if($fp = @fsockopen($url['host'],empty($url['port'])?80:$url['port'],$error)){ fputs($fp,"GET ".(empty($url['path'])?'/':$url['path'])." HTTP/1.1\r\n"); fputs($fp,"Host:$url[host]\r\n\r\n"); while(!feof($fp)){ $tmp = fgets($fp); if(trim($tmp) == ''){ break; }else if(preg_match('/Content-Length:(.*)/si',$tmp,$arr)){ return trim($arr[1]); } } return null; }else{ return null; } } echo getFileSize(http:///200602/02/74/122374/200602022335325121.JPG");$white = imagecolorallocate($im, 0xF9, 0xD7, 0xCD);imagefill($im, 0, 0,$white);$text_color = imagecolorallocate($im, 233, 14, 91);imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);imagepng($im);imagedestroy($im);?>注意这个要把PHP分配内存调大，应用时用大内存服务器
