ID: 22008 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Documentation problem Operating System: all PHP Version: 4.3.0 New Comment:
I've tried the latest CVS and tried to fetch the page you've specified. 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. Previous Comments: ------------------------------------------------------------------------ [2003-02-02 22:06:07] [EMAIL PROTECTED] 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] [EMAIL PROTECTED] 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); ?> ------------------------------------------------------------------------ [2003-02-02 15:46:14] [EMAIL PROTECTED] c) Add a <note> regarding the 'blank lines' comment from Ilia. I don't think strip_tags() needs this <note> but maybe it does (doubtful). ------------------------------------------------------------------------ [2003-02-02 15:41:51] [EMAIL PROTECTED] That or maybe a problem existed because it only gets/strips one line at a time which makes dealing with html tags spanning multiple lines not-so-good. So using this fgetss() example script vs strip_tags(file_get_contents($url)) will yield different results. Reclassifying as a doc problem for fgetss(): a) Add the 0 vs false entity b) Add a warning regarding spanning html tags; offer an alternative ------------------------------------------------------------------------ [2003-02-02 14:44:04] [EMAIL PROTECTED] Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. I think the problem you are seeing may stem from incorrect usage of the fgetss() function. For that reason I am including a sample of a working code for this function below <?php $fp = fopen("http://bugs.php.net/bug.php?id=22008";, "r"); while (($line = fgetss($fp, 4096)) !== FALSE) { echo $line; } fclose($fp); ?> Note that the output of fgetss gets compared to false, this is very important because it is quite likely that fgetss() will return 'blanks' if the line only contains HTML data. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
