Usage
Conversions between bases
\Delight\BaseConvert\Base::convert( '101111000110011100011101110001110011100001000100010100111110', 2, 27 ); // string(13) "5HH1KDF77JELE" // or \Delight\BaseConvert\Base::convert( '2634460662', 8, 16 ); // string(8) "167261B2" // or \Delight\BaseConvert\Base::convert( 'BC671DC7384453E', 16, 10 ); // string(18) "848490771450709310"
Note: Only bases between 2 (inclusive) and 62 (inclusive) are supported via Base::convert
. For larger bases, you must use Alphabet::convert
instead and specify the alphabet that should be used explicitly.
Conversions between alphabets
\Delight\BaseConvert\Alphabet::convert( '219', \Delight\BaseConvert\Alphabet::DECIMAL, \Delight\BaseConvert\Alphabet::ALPHANUMERIC_HUMAN ); // string(2) "Fw" // or \Delight\BaseConvert\Alphabet::convert( '1068880747392', \Delight\BaseConvert\Alphabet::DECIMAL, \Delight\BaseConvert\Alphabet::BINARY ); // string(40) "1111100011011110010000011101101110000000" // or \Delight\BaseConvert\Alphabet::convert( '3012001200067890000406780000912050034500', \Delight\BaseConvert\Alphabet::DECIMAL, \Delight\BaseConvert\Alphabet::ALPHANUMERIC_HUMAN ); // string(26) "4tYhrL3q7ydJrqrj4hp7WjHkWJ" // or \Delight\BaseConvert\Alphabet::convert( '4562245003000071200000100340005636710000', \Delight\BaseConvert\Alphabet::OCTAL, \Delight\BaseConvert\Alphabet::DECIMAL ); // string(36) "784790447634685127626847041410011136" // or \Delight\BaseConvert\Alphabet::convert( '127000450089A00000000BCD00604500323EF100', \Delight\BaseConvert\Alphabet::HEX, \Delight\BaseConvert\Alphabet::DECIMAL ); // string(48) "105259540817262448627958480599765632799008026880" // or \Delight\BaseConvert\Alphabet::convert( 'rxmMbcWYNVfH', \Delight\BaseConvert\Alphabet::ALPHA_HUMAN, \Delight\BaseConvert\Alphabet::DECIMAL ); // string(19) "1413192387433400246" // or \Delight\BaseConvert\Alphabet::convert( "\x44\x25\x31\x3d", \Delight\BaseConvert\Alphabet::BYTE, \Delight\BaseConvert\Alphabet::OCTAL ); // string(11) "10411230475"
Available alphabets
When passing an alphabet to Alphabet::convert
as either the source or the target alphabet, you can use any alphabet that exclusively consists of ASCII or single-byte UTF-8 characters. Of course, no single character may appear more than once in a given alphabet.
Alternatively, you can use any of the following pre-defined alphabets that should be sufficient for many purposes:
\Delight\BaseConvert\Alphabet::ALPHA; \Delight\BaseConvert\Alphabet::ALPHA_HUMAN; \Delight\BaseConvert\Alphabet::ALPHA_LOWERCASE; \Delight\BaseConvert\Alphabet::ALPHA_LOWERCASE_HUMAN; \Delight\BaseConvert\Alphabet::ALPHA_UPPERCASE; \Delight\BaseConvert\Alphabet::ALPHA_UPPERCASE_HUMAN; \Delight\BaseConvert\Alphabet::ALPHANUMERIC; \Delight\BaseConvert\Alphabet::ALPHANUMERIC_AND_PUNCTUATION_HUMAN; \Delight\BaseConvert\Alphabet::ALPHANUMERIC_HUMAN; \Delight\BaseConvert\Alphabet::ALPHANUMERIC_LOWERCASE; \Delight\BaseConvert\Alphabet::ALPHANUMERIC_LOWERCASE_HUMAN; \Delight\BaseConvert\Alphabet::ALPHANUMERIC_UPPERCASE; \Delight\BaseConvert\Alphabet::ALPHANUMERIC_UPPERCASE_HUMAN; \Delight\BaseConvert\Alphabet::ASCII_PRINTABLE; \Delight\BaseConvert\Alphabet::ASCII_PRINTABLE_HUMAN; \Delight\BaseConvert\Alphabet::BASE_32; \Delight\BaseConvert\Alphabet::BASE_58; \Delight\BaseConvert\Alphabet::BASE_64; \Delight\BaseConvert\Alphabet::BASE_64_URL; \Delight\BaseConvert\Alphabet::BASE_85; \Delight\BaseConvert\Alphabet::BINARY; \Delight\BaseConvert\Alphabet::BYTE; \Delight\BaseConvert\Alphabet::DECIMAL; \Delight\BaseConvert\Alphabet::DUODECIMAL; \Delight\BaseConvert\Alphabet::DUODECIMAL_LOWERCASE; \Delight\BaseConvert\Alphabet::DUODECIMAL_UPPERCASE; \Delight\BaseConvert\Alphabet::HEX; \Delight\BaseConvert\Alphabet::HEX_LOWERCASE; \Delight\BaseConvert\Alphabet::HEX_UPPERCASE; \Delight\BaseConvert\Alphabet::OCTAL; \Delight\BaseConvert\Alphabet::QUATERNARY; \Delight\BaseConvert\Alphabet::QUINARY; \Delight\BaseConvert\Alphabet::SENARY; \Delight\BaseConvert\Alphabet::TERNARY; \Delight\BaseConvert\Alphabet::VIGESIMAL; \Delight\BaseConvert\Alphabet::VIGESIMAL_LOWERCASE; \Delight\BaseConvert\Alphabet::VIGESIMAL_UPPERCASE;
Built-in PHP functions
If you prefer a consistent interface for bases of any size, you can replace PHP’s built-in functions for base conversions as follows:
\bindec($n)
can be replaced with …\Delight\BaseConvert\Base::convert($n, 2, 10)
\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::BINARY, \Delight\BaseConvert\Alphabet::DECIMAL)
\octdec($n)
can be replaced with …\Delight\BaseConvert\Base::convert($n, 8, 10)
\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::OCTAL, \Delight\BaseConvert\Alphabet::DECIMAL)
\decbin($n)
can be replaced with …\Delight\BaseConvert\Base::convert($n, 10, 2)
\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::DECIMAL, \Delight\BaseConvert\Alphabet::BINARY)
\decoct($n)
can be replaced with …\Delight\BaseConvert\Base::convert($n, 10, 8)
\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::DECIMAL, \Delight\BaseConvert\Alphabet::OCTAL)
\dechex($n)
can be replaced with …\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::DECIMAL, \Delight\BaseConvert\Alphabet::HEX_LOWERCASE)
\Delight\BaseConvert\Base::convert($n, 10, 16)
(uppercase)
\hexdec($n)
can be replaced with …\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::HEX, \Delight\BaseConvert\Alphabet::DECIMAL)
\Delight\BaseConvert\Base::convert($n, 16, 10)
\hex2bin($n)
can be replaced with …\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::HEX_LOWERCASE, \Delight\BaseConvert\Alphabet::BYTE)
\bin2hex($n)
can be replaced with …\Delight\BaseConvert\Alphabet::convert($n, \Delight\BaseConvert\Alphabet::BYTE, \Delight\BaseConvert\Alphabet::HEX_LOWERCASE)
base_convert($n, $fromBase, $toBase)
can be replaced with …\Delight\BaseConvert\Base::convert($n, $fromBase, $toBase)
