Bug #21453 strip_tags behaviour change
Submitted: 2003-01-06 01:14 UTC Modified: 2003-01-06 16:16 UTC
From: pw0kt32001 at sneakemail dot com Assigned:
Status: Closed Package: Strings related
PHP Version: 4.3.0 OS: Windows XP
Private report: No CVE-ID:

A "<" as plaintext is something strip_tags can't make much sense of, sure. My previous report ( http://bugs.php.net/bug.php?id=21253 ) was indeed bogus, but what about this.

<?php
print("<pre>");
$test = "<table>\n<tr><td>first cell before < first cell after</td></tr>\n<tr><td>second cell before < second cell after</td></tr>\n</table>\n";
$testarray = explode("\n",strip_tags($test));
print_r($testarray);
print("</pre>");

/*
4.2.3
=====
Array
(
    [0] => 
    [1] => first cell before 
    [2] => second cell before 
    [3] => 
    [4] => 
)

4.3.0
=====
Array
(
    [0] => 
    [1] => first cell before 
)
*/
?>

Is this also per design? Parsing third-party webpages created by someone/some program that disregards that &lt; should be used instead of "<" became a bit more difficult with 4.3.0. Not hard to code around, but certainly an annoyance compared to 4.2.3.
