Bug description:htmlspecialchars() silently failing
Description:
------------
htmlspecialchars() no longer provides warnings in PHP 5.4
This is specially worrying as 5.4 changes its default charset
from ISO-8859-1 to UTF-8.
So the same string that passed flawlessly through 5.3, will
now silently output nothing in 5.4 (and htmlspecialchars
is one of the last things to check!).
In 5.3 the following can produce:
var_dump( htmlspecialchars("a\237a", ENT_COMPAT, 'UTF-8') );
PHP Warning: htmlspecialchars(): Invalid multibyte sequence in argument in
php shell code on line 1
string(0) ""
whereas in 5.4:
var_dump( htmlspecialchars("a\237a", ENT_COMPAT, 'UTF-8') );
string(0) ""
The explicit UTF-8 is to make both work the same,
htmlspecialchars("a\237a") *works* in 5.3 (but it may not be
in your page encoding).
The reason is clear, php_error_docref() of php_escape_html_entities_ex
is gone in 5.4 and trunk.
I attach a patch against 5.4 branch readding the warning (should apply fine
in
trunk, moved 5 lines below)
