Request #46478 htmlentities() uses obsolete mapping table for character entity references
Submitted: 2008-11-04 12:56 UTC Modified: 2009-12-22 05:50 UTC
From: for-bugs at hnw dot jp Assigned: moriyoshi (profile)
Status: Closed Package: Feature/Change Request
PHP Version: 5.2.6 OS: *
Private report: No CVE-ID: None
 [2008-11-04 12:56 UTC] for-bugs at hnw dot jp
Description:
------------
ext/standard/html.c has incorrect mapping table which htmlentities() uses.

html.c is based on http://www.unicode.org/Public/MAPPINGS/OBSOLETE/UNI2SGML.TXT, but this mapping table is obsolete and not compatible with HTML4.0 or XHTML1.0. For example, U+2235(which is encoded to "\xe2\x88\xb5" with UTF-8) is not in http://www.w3.org/TR/xhtml1/DTD/xhtml-symbol.ent, but htmlentities() returns "∵".

U+226A(≪) and U+226B(≫) are similler case.

Reproduce code:
---------------
<?php var_dump(htmlentities("\xe2\x88\xb5", ENT_QUOTES, "utf-8"));

Expected result:
----------------
string(3) "??"

Actual result:
--------------
string(8) "&becaus;"

I think this is a bug, but correcting the table should break BC too.
