Ive come across something that i just dont know how to approach.
Basically I have two pages of php.
Page 1 creates a file with lines of data, each line of data looks like this:
Now what I need to do with this data is take the last 4 digits of the strings (which are individual stamps of time etc 4:15pm) and work out:
Please call MrSmith immediately. On telephone number 02392666666. Thank you.1615
1.How many lines appearred within the last hour.
2.If the last line is new (which would only be true if the time stamp on the line is equal to the current one of date('Gis').
Here is how far I have come so far. Any help would be greatly appreciatted.
$filename = 'phonecsv/'. date('ymd'). '.csv';
$fp = fopen($filename, "r");
// works out how many callback requests today
$lines = count(file($filename));
echo "Today there have been $lines callback requests <br/>";
// needs to work out from time sequence how many in last hour
echo "In the last hour there have been x callback requests<br/>";
// needs to work out from time sequence if new message
echo "This is the latest callback request<br/>";
$data = fgets($fp);
echo "The file $filename does not exist!! Check the svr file and callback forwarder!<br/>";
