As far as I can tell the function had worked correctly, only non-html output was displayed. P.S. Philip the fgetss() function is supposed to handle tags that span multiple lines, so that should not be a problem. ------------------------------------------------------------------------ [2003-02-02 22:06:07] airtravel at anet dot ne dot jp This is something to do with <!DOCTYPE> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd"> seems to be causing problem. Again PHP4.2.3 or earlier treats this without problem. ------------------------------------------------------------------------ [2003-02-02 21:08:46] airtravel at anet dot ne dot jp Thank you for your comments. I found this problem only occurs when parsing specific html. Please try the following URL to see my problem. Thank you. <?php $fp = fopen("http://adds.aviationweather.gov/projects/adds/metars/index.php?metarIds=ksfo", "r"); while (($line=fgetss($fp, 4096))!==FALSE) { echo $line; } fclose($fp); ?> <?php $fp = fopen("http://adds.aviationweather.gov/projects/adds/metars/index.php?metarIds=ksfo", "r"); while (($line = strip_tags(fgets($fp, 4096)))!==FALSE) { echo $line; } fclose($fp); ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
