PHP Bug Type: ICONV related
Bug description: iconv_substr, incorrect behaviour with $length=0
Description:
------------
According to documentation and reflection: iconv_substr has third argument
$length, default value is 0, but iconv_substr returns different result when
argument is not passed and when argument is passed as zero. (Now it's not
possible to call iconv_substr with $charset argument and preserve correct
behaviour.)
Reproduce code:
---------------
var_dump(iconv_substr('foobar', 3)); // "bar"
var_dump(iconv_substr('foobar', 3, 0)); // ""
var_dump(iconv_substr('foobar', 3, NULL, 'UTF-8')); // ""
Expected result:
----------------
string(3) "bar"
string(0) "bar"
string(0) "bar"
Actual result:
--------------
string(3) "bar"
string(0) ""
string(0) ""
