Functions

hexEncode()

Encodes binary data into a lowercase hexadecimal string.

hexEncode(string $binary) : string

Thin wrapper around bin2hex() provided for API symmetry with the other helpers of this package (hexDecode(), base64UrlEncode()).

The function is binary-safe and always produces lowercase output, which matches the convention used for hashes, tokens and HMAC tags across the Oihana ecosystem.

Parameters
$binary : string

Raw bytes to encode. May be empty.

Tags

echo hexEncode( '' ) ;           // ""
