[SOLVED] Reading as text file backwards

[eon201]

Hi everyone.

Im currently reading server log files from my server and taking the data into arrays. To make sure im getting the most relevant data im doing a time check to only get the latest hours data.

The only problem?? The file is HUGE, and the code scans the whole file before pulling the relevant data. Which is annoying considering the most recent data is at the bottom of the file!

So does anyone know of a way to read the file line by line but backwards??

Thanks again. Eon201

$this_array = array_reverse($this_array);

That will reverse the array...

ok thanks (again!) Rakuli.

So therefore I should take my code:

PHP: Select all

    if (file_exists($filename)) // Does the corresponding filename exist - if yes then
    {
        $fp = fopen($filename, "r"); //Open the server log
        $content = fread($fp, filesize($filename));     // Read the server log
        
        $content = explode("\n", $content); 

And implement your code by doing this?

PHP: Select all

    if (file_exists($filename)) // Does the corresponding filename exist - if yes then
    {
        $fp = fopen($filename, "r"); //Open the server log
        $content = fread($fp, filesize($filename));     // Read the server log
                 $content  = array_reverse($content );

        $content = explode("\n", $content); 

Thanks. Eon201

Not quite

You have it in the wrong order..

PHP: Select all

 if (file_exists($filename)) // Does the corresponding filename exist - if yes then

    {

        $fp = fopen($filename, "r"); //Open the server log

        $content = fread($fp, filesize($filename));     // Read the server log

                 // Create the array

        $content = explode("\n", $content);

        // now reverse it

        $content  = array_reverse($content );
