(PHP 4, PHP 5, PHP 7)
rawurlencode — URL-encode according to RFC 3986
strThe URL to be encoded.
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 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.
| Version | Description |
|---|---|
| 5.3.4 | Tilde characters are no longer encoded when rawurlencode() is used with EBCDIC strings. |
| 5.3.0 | Now conforms to » RFC 3986. |
