Re: file writing question

Hello all,

    Thanks in advance.  I have a quesetion about writing to files.  I am

successfully opening a file and writing to it, but I'm having problems inserting text. My file currently has the following structure: *************** [index] 24 1073946700 *************** The second line in the file represents an incremented number. And the third line is a unix timestamp of when the incremented number was last incremented. I will have a script that will allow a user to decrement this number, and revert back to the timestamp that goes along with the decremented value. Basically, my file will need the following structure: *************** [index] 3 1073946709 1073946704 1073946700 *************** Since the incremented number is at 3, there should be 3 timestamps in a "stack" order. Overwriting the sole number for incrementing or decrementing is no problem. However, inserting a new timestamp is where I get stuck. The current timestamp is over-written rather than inserting a new one. Here is my code: <? function hitcount($pagename) { $ctrPos; $timeStampPos; $buffer = ''; $formatName = '[' . $pagename . ']'; $fileHandle = -1; //Make sure the file exists if(file_exists("Reports/hitcount.txt") == TRUE) { //Attempt to open the file with read AND write priveleges $fileHandle = fopen('Reports/hitcount.txt','r+'); //Make sure we have a valid file pointer if($fileHandle) {

    //Attempt to seek to the given page name section
    $buffer = fgets($fileHandle, 1024);
    while(!feof($fileHandle) && $buffer != $formatName . "\r\n")
    {
     $buffer = fgets($fileHandle, 1024);
    }

    //Make sure we are not EOF
    if(feof($fileHandle) == FALSE)
    {

     //get the current pointer position
     $ctrPos = ftell($fileHandle);

     //read the next line which is the current hit count
     $buffer = fgets($fileHandle, 1024);
     $timeStampPos = ftell($fileHandle);

     //increment the hit count
     $buffer = $buffer + 1;

     //seek to where we know the hit count is
     fseek($fileHandle, $ctrPos);

     //overwrite the hit count
     fwrite($fileHandle, $buffer . "\r\n");

     //insert the new time stamp
     fwrite($fileHandle, time() . "\r\n");
    }
    else
    {
     //We ARE EOF so we need to add the new page name here and insert the

first hit count and timestamp

     fwrite($fileHandle, $formatName . "\r\n");
     fwrite($fileHandle, "1\r\n" . time());
    }

} rewind($fileHandle); echo("File Contents: <BR>***************<BR>"); while(!feof($fileHandle)) {

    $buffer = fgets($fileHandle, 1024);
    echo($buffer . "<BR>");

} echo("***************<BR>"); fclose($fileHandle); } } ?>
