How can i convert a multidimensional array to string and vice versa using php?

[mohan lal]

Hi..

I have a multi dimensional array i want to convert this array to string and saved in to a file.Also need to convert string that stored in the file to the previous array for further processing. (i.e the file is like a table in the database ). Is it possible to convert the array to string and then back to array using php?
If anyone knows please help me thanks in advance...

Look at serialize and unserialize.
