I'm relatively new to programming and I'm currently working on a project where I need to reverse all the bits in a variable using PHP. I've heard that this can be accomplished using bit manipulation techniques, but I'm not quite sure how to go about it.
To give you some context, I have a variable in my PHP code that holds a binary value. Let's say the value is 101010. What I want to do is reverse all the bits in this variable so that it becomes 010101.
I've been reading up on bit manipulation and I understand that bitwise operators like shift and bitwise NOT are commonly used for such operations. However, I'm not sure how to apply these operators in this specific scenario.
I would greatly appreciate it if someone could guide me on how to achieve this reversal of bits in PHP. Are there any specific functions or operators that I should be using? An example code snippet would be immensely helpful.
Thank you in advance!
