base64_binary ( string )
string | A base64-encoded string. Valid characters include a-z, A-Z, 0-9, /, and +. |
The function converts a base64-encoded string to a binary type. The string length cannot have a remainder of 1 when divided by 4, as it makes the encoding invalid. Optionally, use one or two padding characters, '=' in order to make the length divisible by 4.
base64_binary ( 'bGVhc3VyZS4=') returns 6C6561737572652E.
