At the moment I have got a script that logs day, time, date etc like the following:

Friday 10th of April 2009 02:34:16 PM

Friday 10th of April 2009 02:34:21 PM

 

Is it possible to use PHP to search through this data to find duplicates?

 

E.g.

 

<?php
$DATE = ".date.";

if ($DATE>1){
echo "This has happened more than once today";
}
else
{
echo "This is the first time that this has happened today";
}
?>

 

The information is not essential so the only other way I could think of is when doing the original fwrite is to fwrite something to a file and then run a cron job every 24 hours to empty the file and then run a check to see if the file is empty or not.

Is this going to a flat text file or are you using a database?

A flat txt file

In that case I would output each line/date to an array, then loop through the array for each stored date to find duplicates using the in_array() function.

 

EDIT:

 

Or you could even use the array_search() function...
