Sasuun Posted March 5, 2006 Share Posted March 5, 2006 I'm using eval to execute php I have stored in a mysql database for a blocks system, but in order to aviod any problems using function such as header() or session_start() after output has been sent, I store all of my output in a variable $OUTPUT and on the last line of my script echo that var. This was all going fine until I added a php filter to my block system, which worked great, except my output would always be printed above everything else on my site, so I went to php.net and read up on the eval() function, and lo and behold I finally realized they had a tip for using eval[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Tip: As with anything that outputs its result directly to the browser, you can use the output-control functions to capture the output of this function, and save it in a string (for example).[/quote]I have no idea how to use output-control functions, and I've been reading about them searching for a couple of hours with no luck Does anyone know how I could capture the output and put it in my $OUTPUT var?incase it helps, here is my get_blocks function[code]function get_blocks($position) { $ACHTML = ''; #initialize variable and make sure it doesn't have any data in it $sql = "SELECT * FROM ac_blocks WHERE `position` = '$position' ORDER BY `order` ASC"; $get = mysql_query($sql) or die(mysql_error()); while ($blocks = mysql_fetch_array($get)) { if ($position == "C") { $ACHTML .= site_box($blocks['block_title']); }else { $ACHTML .= make_menu($blocks['block_title']); } if ($blocks['filter_method'] == 0)#bbcode { $ACHTML .= $this->bbcode2html($blocks['content'],'1'); } elseif ($blocks['filter_method'] == 1)#we're parsing raw php { $ACHTML .= eval($blocks['content']); }else { $ACHTML .= "block error"; } $ACHTML .= close_menu(); } return $ACHTML; }[/code] Quote Link to comment https://forums.phpfreaks.com/topic/4157-using-output-control-functions-to-capture-output-from-eval/ Share on other sites More sharing options...
