Empty text file when there is over XXXX lines of text.

Posted on 16th Feb 2014 07:03 pm by admin


define("RANDOM_FILE","/public_html/random.txt");
$randomEntry = "This goes in text file.n";
{
$randomFile = fopen(RANDOM_FILE,"a");
}
fwrite($randomFile,$randomEntry);
fclose($randomFile);


This adds text to a random.txt file. How do you make it also empty the file when there is over say 1,000 lines of data?

Each line has 588 bytes of data, or 588K when it has 1,000 lines. How big does a text file need to be before it can slow the site down when the script looks for the random line?
