Folks,
Why should htmlentities() use the default_charset for $charset with this
example, taken from ext/standard/tests/strings/htmlentities10.phpt?
<?php
ini_set('mbstring.internal_encoding','pass');
ini_set('default_charset','cp1252');
var_dump(htmlentities("\x82\x86\x99\x9f", ENT_QUOTES, ''));
?>
The test script expects the output to be:
string(28) "‚†™Ÿ"
According to the PHP Manual, the htmlentities() syntax is:
string htmlentities ( string $string [, int $quote_style [, string
$charset [, bool $double_encode ]]] )
For the parameter charset:
"Like htmlspecialchars(), it takes an optional third argument charset which
defines character set used in conversion. Presently, the ISO-8859-1
character set is used as the default." It goes on to list the supported
values for charset and states: "Note: Any other character sets are not
recognized and ISO-8859-1 will be used instead."
Therefore, when $charset = '' I would expect that
htmlentities("\x82\x86\x99\x9f", ENT_QUOTES, '') would use ISO-8859-1 since
the null string is not listed as a supported value. Also, it does not
mention the use of default_charset. Furthermore, when default_charset = '',
PHP states that ISO-8859-1 will be used as the default.
Since the $charset is optional, I would expect
htmlentities("\x82\x86\x99\x9f", ENT_QUOTES) would use the default_charset,
but not htmlentities("\x82\x86\x99\x9f", ENT_QUOTES, ''). However, test
scripts ext/standard/tests/strings/htmlentities10.phpt, htmlentities11.phpt,
and htmlentities13.phpt all expect the default_charset to be used when
charset=''.
Thanks.
