Htmlentities and htmlspecialchars refuse to process string
Since the last update to PHP5 5.4.0-3 in my Debian box, I noticed that some pages have empty fields where text from the MySQL database should be.
I played around a bit and found the problem.
<?php
$scselect = mysql_query("SELECT `name` FROM `forum_threads` WHERE `forum` = '1' ORDER BY `timestamp` DESC") or exit((mysql_error()));
while ($scrow=mysql_fetch_array($scselect))
{
var_dump($scrow['name']);
var_dump(htmlentities($scrow['name']));
}
?>
strange is what is printed:
string(18) "php hu3: the Forum"
string(0) ""
string(18) "php hu2 score-rule"
string(0) ""
string(6) "php hu"
string(0) ""
string(15) "HU 8: Binarycnt"
string(0) ""
but if i use htmlentities with hardcoded content -> htmlentities ("test"); it works like a charm. Also if I do this:
var_dump("a".$scrow['name']);
he also says
string(0) ""
But this is getting weirder. If I use htmlentities or htmlspecialchars with any other variable from the database it works fine.
var_dump(htmlspecialchars($scrow['ID'])); // prints for example string(2) "87"
what could be the reason for this?

The recommended approach is to hard-code the character set every time you use htmlentities.
This is a function to call htmlentities and is independent of the default character set. migration54
