Hi Shiavarj rh,

create the file object

read the contents of the file

split them into an array (explode()) on the condition of line break i.e. \n

sort the array(array_sort())

reverse the array (use array_reverse())

then re-join the array use implode() function (so that you can

join them on to a condition i.e. \n)

rewrite the file

hope that helps,
