print_r , var_dump used for debugging purpose.
The var_export returns the php code. We could load this content in variable and later can be used.
var_dumps same as print_r except it shows the structure with types.
var_exports same as var_dump except it returns the php code as string format.
These helps to gothru the contents of the variables recursively in readable format.
