Question

I have a logging script which saves to file logs.
I would like to know how I can read X amount of records from the end of the file without pulling all the data from the file.

This is an example of a record in the file:

[02.10.2011, 23:15:09] User ‘dor’ added comment.

This is the insertion code:

public function logError( string $errorMessage )
{
    if( emtpy( trim( $errorMessage ) ) )
    {
        return false;
    }

    $errorMessage = trim( strip_tags( htmlspecialchars( $errorMessage ) ) );
    $errorTime = date( 'd.m.Y, H:i:s' );

    $errorRow = "[{$errorTime}] {$errorMessage}\n";

    if( @is_writable( "{$this->logsDir}{$this->logFile}" ) )
    {
        if( fwrite( $this->fileHandler , $errorRow) === false )
        {
            return false;
        }
    }

    return true;
}

You want to use fseek function with negative offset and SEEK_END as whence

Look into documentation of fseek http://php.net/fseek
