PHP converts any number of binary numbers into a 10 binary method

This article mainly introduces the PHP implementation of the arbitrary number of conversion to 10 binary method, involving the PHP system conversion of the relevant skills, very practical value, the need for friends can refer to the next

The example in this paper is about how the PHP implementation converts any number of binary numbers into 10 binary. Share to everyone for your reference. Specific as follows:

PHP converts any number of binary numbers to 10, for example, 8 to 10, and 16 to 10 in binary.
