note 79916 added to function.require

I found a strange behavior with require/include when showing images (gif,jpeg) with header() - from a blob/mysql or directly from a file. When using require or include, like the following code: require (".config.php"); $conexao=mysql_connect("localhost",$userdb,$passwddb); $selecao=mysql_select_db($database,$conexao); $sql = "select image FROM tb_img WHERE id= $_GET['id']"; $result = mysql_query("$sql") or die mysql_error(); mysql_fetch_array($result,MYSQL_NUM); header("Content-Type: image/jpeg"); echo $res[0] ; The image cannot be displayed and the error goes like: Error interpreting JPEG image file (Not a JPEG file: starts with 0x20 0x0a) The file .config.php is nothing but some declaration of variables inside the tags '<?' '?>'. Interestingly, when removing the line: require (".config.php"); and declaring variables locally, the image is displayed ok. I noticed that for some reason, 2 bytes are appended to the image when using require, messing up with the browser interpretation of the image. Any clues? Or is it a bug? ---- Server IP: 200.185.126.110 Probable Submitter: 200.198.55.3 ---- Manual Page -- http://www.php.net/manual/en/function.require.php Edit -- https://master.php.net/note/edit/79916 Del: integrated -- https://master.php.net/note/delete/79916/integrated Del: useless -- https://master.php.net/note/delete/79916/useless Del: bad code -- https://master.php.net/note/delete/79916/bad+code Del: spam -- https://master.php.net/note/delete/79916/spam Del: non-english -- https://master.php.net/note/delete/79916/non-english Del: in docs -- https://master.php.net/note/delete/79916/in+docs Del: other reasons-- https://master.php.net/note/delete/79916 Reject -- https://master.php.net/note/reject/79916 Search -- https://master.php.net/manage/user-notes.php
