I would recommend you read the file into a string and use the split()
function to split the string contents into an array (such as
$entryArray) based on newlines, then you can extract the last element
using end() and then split that into another array (such as
$lastEntryArray) based on commas, and then $lastEntryNumber =
$lastEntryArray[0];
