PHP rawurlencode Function: Description, Parameters, and Examples
The article explains PHP's rawurlencode() function, detailing its RFC 3986‑based URL encoding behavior, signature, parameter description, return value, and provides two practical code examples demonstrating how to encode special characters in FTP and HTTP URLs.
The rawurlencode() function in PHP encodes a string according to RFC 3986, converting all non‑alphanumeric characters except -_. into percent‑encoded sequences.
Signature: string rawurlencode(string $str)
Parameters: $str – the URL or string to be encoded.
Return value: a string where characters other than -_. are replaced with % followed by two hexadecimal digits, preserving the original meaning of the URL.
Example 1:
<?php
echo '<a href="ftp://user:' . rawurlencode('foo @+%/') . '@ftp.example.com/x.txt">';
?>Output:
<a href="ftp://user:foo%20%40%2B%25%[email protected]/x.txt">Example 2:
<?php
echo '<a href="http://example.com/department_list_script/' . rawurlencode('sales and marketing/Miami') . '">';
?>Output:
<a href="http://example.com/department_list_script/sales%20and%20marketing%2FMiami">Laravel Tech Community
