What is the best way to write an array to a file in PHP?

The serialize() function is used to create a storable representation of a variable in PHP.

 

To store an array to a file, you first use the serialize() function to change an array into a string. Save the string in a file using file I/O, so fwrite() or a similar function. When reading it use unserialize() to get the original array again.
