URL::Encode(3) User Contributed Perl Documentation URL::Encode(3)

URL::Encode - Encoding and decoding of "application/x-www-form-urlencoded" encoding.

    $octets = url_decode($octets);
    $string = url_decode_utf8($octets);
    
    $octets = url_encode($octets);
    $octets = url_encode_utf8($string);
    
    $params = url_params_flat($octets [, $utf8 = false]);
    $params = url_params_mixed($octets [, $utf8 = false]);
    $params = url_params_multi($octets [, $utf8 = false]);
              url_params_each($octets, $callback [, $utf8 = false]);

This module provides functions to encode and decode strings into and from the "application/x-www-form-urlencoded" encoding.

The "application/x-www-form-urlencoded" format encodes a ordered data sets of pairs consisting of a name and a value, with pairs seperated by ampersand or semicolon and names and values seperated by the equal sign. Space characters are replaced with plus sign and any characters not in the unreserved character set is encoded using the percent-encoding scheme also used for resource identifiers. A percent-encoded octet is encoded as a character triplet, consisting of the percent character "%" followed by the two hexadecimal digits representing that octet's numeric value.

The unreserved character set includes the uppercase and lowercase letters, decimal digits, hyphen, period, underscore, and tilde.

    $octets = url_decode($octets);

Returns a decoded representation of the given URL-encoded $octets as an octet string.

    $string = url_decode_utf8($octets);

Returns a decoded representation of the given URL-encoded $octets in UTF-8 encoding as a character string.

    $octets = url_encode($octets);

Returns a URL-encoded representation of the given $octets as an octet string.

    $octets = url_encode_utf8($string);

Returns a URL-encoded representation of $string in UTF-8 encoding as an octet string.

    $params = url_params_flat($octets);
    $params = url_params_flat($octets, $utf8);

Parses a URL-encoded data set of name/value pairs from the given octets. Returns an ARRAY reference containing the URL-decoded name/value pairs in order.

    $params = url_params_flat('foo=A&foo=B&bar=C');
    $params; # [ foo => 'A', foo => 'B', bar => 'C' ]

    $params = url_params_mixed($octets);
    $params = url_params_mixed($octets, $utf8);

Parses a URL-encoded data set of name/value pairs from the given octets. Returns a HASH reference containing the URL-decoded name/value pairs. Multiple occurrences of a parameter will result in an ARRAY reference holding all the values for that parameter in order.

    $params = url_params_mixed('foo=A&foo=B&bar=C');
    $params; # { foo => [ 'A', 'B' ], bar => 'C' }

    $params = url_params_multi($octets);
    $params = url_params_multi($octets, $utf8);

Parses a URL-encoded data set of name/value pairs from the given octets. Returns a HASH reference containing the URL-decoded name/value pairs. Values are stored in an ARRAY reference.

    $params = url_params_multi('foo=A&foo=B&bar=C');
    $params; # { foo => [ 'A', 'B' ], bar => [ 'C' ] }

    url_params_each($octets, $callback);
    url_params_each($octets, $callback, $utf8);

Parses a URL-encoded data set of name/value pairs from the given octets. Invokes the given callback for each URL-decoded name/value pair.

    $callback = sub {
        my ($name, $value) = @_;
    };
    
    url_params_each($octets, $callback);

None by default. All functions can be exported using the ":all" tag or individually.

(F) Usage: %s
Subroutine called with wrong number of arguments.
(F) Wide character in octet string
(F) Malformed UTF-8 in URL-decoded octets

The URL::Encode::XS module provides faster C/XS implementations of the functions found in this module. This module will automatically use URL::Encode::XS if it's installed.
