How do I unpack a binary string in PHP?

How can I do this Perl code in PHP?

 print unpack ("H*", pack ("B*", "00000000100000012000000" ));
Solution

  • Since pack/unpack in PHP doesn't support the B type, you'll have to use PHP's other functions instead. In this case, dechex and bindec.

    echo dechex( bindec( "00000000100000012000000" ));

    Edit: Or do it in a single function with base_convert:

    echo base_convert("00000000100000012000000", 2, 16);
