FILTER_FLAG_NO_ENCODE_QUOTES
|
Equivalent to calling htmlspecialchars with ENT_QUOTES set. Encoding quotes can
be disabled by setting FILTER_FLAG_NO_ENCODE_QUOTES. Like htmlspecialchars, this
filter is aware of the default_charset and if a sequence of bytes is detected that
makes up an invalid character in the current character set then the entire string is rejected resulting in a 0-length string.
When using this filter as a default filter, see the warning below about setting the default flags to 0.
