PHP Bug Type: SQLite related
Bug description: sqlite_escape_string on '' or null returns wrong value
Description:
------------
sqlite_escape_string on '' (the empty string) or null returns the wrong
value.
I would guess that:
sqlite_escape_string ('') should return '',
and
sqlite_escape_string (null) should return null.
Additionally, you can see that what sqlite_escape_string actually does
return in these cases is a mangled version of the previous non-null input
string.
This bug appears to have been fixed in PHP5, but not yet in PHP4.
