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.

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">
