How to seperate data from line in txt file

[phantom_turtle]

I want to know if it is possible to seperate data from a line in a text file. For example:

Text file contains the folowing lines:

somedata somedata somedata somenumber
somedata somedata somedata somenumber
somedata somedata somedata somenumber
somedata somedata somedata somenumber

Like a log.

What I want to be able to do is read a line from the file and just get the "somenumber" bit on the end and assign it to a variable to use in the php script.

Code: Select all

$variable = "somenumber"

For instance so that you can add up all the "somenumbers" at the end of the lines and have a total of all the some numbers for the whole text file.

Any suggestions or code would be greatly apreciated.

Depending on your data, you could use sscanf() if you know the format (eg "%s %s %s %i") or possibly split() to put the data into an array, and just use the last value of that array.

Hope this helps

I would imagine the data in your datafile is separated by a colon, coma, or maybe a space... you say your interested only in the last item.

Code: Select all

$datafilename = "datafile.log";
$datafile = fopen($datafilename, "r") or die("Couldn't Open");
$data = fread($datafile, filesize($datafilename) or die ("Couldn't Read");
fclose($datafile);

$data = split("\r", $data);

foreach ($data as $dataline) {
  //STRRCHR SEARCHES FOR LAST OCCURANCE OF ':' AND RETURNS THE REST OF THE STRING
  $THIS = strrchr($dataline, ":");

  echo $THIS;
}
