The second value is the number of spaces to shift, dint realize that. Thanks for your time Chris. Angelo - Original Message - From: "Chris Boget" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; Sent: Monday, September 26, 2005 2:02 PM Subject: Re: [PHP] Bi

Re: [PHP] Bitwise operators

I tested; I don't want to waste peoples time. Rewriting the question: this outputs: c = 32 d = 0 The question is why? First row is the bit's number and the second row is the bit's value: #8 | #7 | #6 | #5 | #4 | #3 | #2 | #1 --- 128 | 64 | 32 | 16 | 8 |
