[PHP] Re: why does trim() remove NUL? From: _lallous (elias_bachaalany <email protected>)

I guess if strlen() fails it returns 0 and if string has no length then it
also returns zero.

I don't think PHP's strings are zero terminated.

$str = "abc\xab\x00defgh";
echo $str;
outputs: abc½ defgh

and doesn't truncate the string.
