note 58295 added to function.get-headers

This is a modified version of code from "stuart at sixletterwords dot com", at 14-Sep-2005 04:52. This version tries to emulate get_headers() function at PHP4. I think it works fairly well, and is simple. It is not the best emulation available, but it works. Features: - supports (and requires) full URLs. - supports changing of default port in URL. - stops downloading from socket as soon as end-of-headers is detected. Limitations: - only gets the root URL (see line with "GET / HTTP/1.1"). - don't support HTTPS (nor the default HTTPS port). <?php if(!function_exists('get_headers')) { function get_headers($url,$format=0) { $url=parse_url($url); $end = "\r\n\r\n"; $fp = fsockopen($url['host'], (empty($url['port'])?80:$url['port']), $errno, $errstr, 30); if ($fp) { $out = "GET / HTTP/1.1\r\n"; $out .= "Host: ".$url['host']."\r\n"; $out .= "Connection: Close\r\n\r\n"; $var = ''; fwrite($fp, $out); while (!feof($fp)) { $var.=fgets($fp, 1280); if(strpos($var,$end)) break; } fclose($fp); $var=preg_replace("/\r\n\r\n.*\$/",'',$var); $var=explode("\r\n",$var); if($format) { foreach($var as $i) { if(preg_match('/^([a-zA-Z -]+): +(.*)$/',$i,$parts)) $v[$parts[1]]=$parts[2]; } return $v; } else return $var; } } } ?> ---- Manual Page -- http://www.php.net/manual/en/function.get-headers.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58295 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58295&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58295&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58295&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58295&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58295&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58295&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58295&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58295&report=yes Search -- http://master.php.net/manage/user-notes.php
