Php performs binary conversion

1. Bindec-- binary number to decimal number

You can use the bindec (binary string) function, which converts binary numbers to decimal numbers.

Output result:

3115877

2. Decbin-- decimal number to binary number

You can use the decbin (decimal value) function, which converts a decimal number to a binary number.

Output result:

11111000110011111

3. Octdec-- octal number to decimal number

You can use the octdec (octal string) function, which converts octal numbers to decimal numbers.

Output result:

3010158770

4. Decoct-- decimal number to octal number

You can use the decoct (decimal value) function, which converts decimal numbers to octal numbers.

Output result:

36123063106

5. Hexdec-- hexadecimal number to decimal number

You can use the hexdec (hexadecimal string) function, which converts hexadecimal numbers to decimal numbers.

Output result:

3010460713430527

6. Dechex-- decimal number to hexadecimal number

You can use the dechex (decimal value) function, which converts decimal numbers to hexadecimal numbers.

Output result:

1ea63346

7. Base_convert-- arbitrary binary conversion

Using the base_convert (number or string to be converted, primitive, binary to be converted) function, it can convert between arbitrary radix

Just set "bindec (binary string, 2,10)" to convert a binary number to a decimal number.

Output result:

Decimal numbers can be converted to binary numbers by setting "bindec (decimal value, 10,2)"

Output result:

You can convert octal numbers to decimal numbers by setting "bindec (octal string, 8,10)"

Output result:

Decimal numbers can be converted to octal numbers by setting "bindec (decimal value, 10,8)"

Output result:

Set "bindec (hexadecimal string, 16,10)" to convert hexadecimal numbers to decimal numbers

Output result:

The decimal number can be converted to hexadecimal number by setting "bindec (decimal value, 10,16)"

Output result:
