Description
string
rawurlencode ( string str)
Returns a string in which all non-alphanumeric characters except
-_. have been replaced with a percent
(%) sign followed by two hex digits. This is
the encoding described in RFC 1738 for protecting literal
characters from being interpreted as special URL delimiters, and
for protecting URL's from being mangled by transmission media
with character conversions (like some email systems). For
example, if you want to include a password in an FTP URL:
Example 1. rawurlencode() example 1
<?php
echo '<a href="ftp://user:', rawurlencode('foo @+%/'),
'@ftp.example.com/x.txt">';
?>
|
|
Or, if you pass information in a PATH_INFO component of the URL:
Example 2. rawurlencode() example 2
<?php
echo '<a href="http://example.com/department_list_script/',
rawurlencode('sales and marketing/Miami'), '">';
?>
|
|
