pack and unpack

[learnphp25]

Hi,

Can anyone give some explanation on these two php functions. Or post some links that have clear explanation on these functions. I am kind of not clear on these after reading about these in the php website.

Thank you.

What don't you understand? Why are you using them if you don't know what they do? I am not sure what more you can explain than they change data to and from binary to any specified format. Never used them and I am not entirely sure where I would, so maybe if you tell what you're trying to do?

I am using a database(berkel ey db) where the data is stored in binary format. I want to use pack function to convert some values into binary so that i can compare them directly with the data in the database. I am doing so because, converting all the data in the db and comparing it with the values i said is taking a lot of time. The data base is very huge and time is important for me over here.

The value of one record is a long sequence of binary data and i take only the required no of bits. like say a sequence of 8 bits.

Can you help me now?

So do you get an error when using the unpack() function? I have never used it, and I was hoping someone who had would see this thread. What happens when you do: unpack($your_bi nary_code) ?
