LEARN ABOUT PHP
rawurlencode
RAWURLENCODE(3) 1 RAWURLENCODE(3)
rawurlencode - URL-encode according to RFC 3986
SYNOPSIS
string rawurlencode (string $str)
DESCRIPTION
Encodes the given string according to RFC 3986.
PARAMETERS
o $str
- The URL to be encoded.
RETURN VALUES
Returns a string in which all non-alphanumeric characters except -_.~ have been replaced with a percent ( %) sign followed by two hex dig-
its. This is the encoding described in RFC 3986 for protecting literal characters from being interpreted as special URL delimiters, and for
protecting URLs from being mangled by transmission media with character conversions (like some email systems).
Note
Prior to PHP 5.3.0, rawurlencode encoded tildes ( ~) as per RFC 1738.
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.3.4 | |
| | |
| | Tilde characters are no longer encoded when |
| | rawurlencode(3) is used with EBCDIC strings. |
| | |
| 5.3.0 | |
| | |
| | Now conforms to RFC 3986. |
| | |
+--------+---------------------------------------------------+
EXAMPLES
Example #1
including a password in an FTP URL
<?php
echo '<a href="ftp://user:', rawurlencode('foo @+%/'),
'@ftp.example.com/x.txt">';
?>
The above example will output:
<a href="ftp://user:foo%20%40%2B%25%2F@ftp.example.com/x.txt">
Or, if you pass information in a PATH_INFO component of the URL:
Example #2
rawurlencode(3) example 2
<?php
echo '<a href="http://example.com/department_list_script/',
rawurlencode('sales and marketing/Miami'), '">';
?>
The above example will output:
<a href="http://example.com/department_list_script/sales%20and%20marketing%2FMiami">
