add one to text file..with a twist

[InfinityDesigns]

Hi,

I have a .txt file that contains a variable for a .swf. Since it is to be used in flash it needs to be of the form var1=2, however i wanted to increase the number every time my script is used. At the moment i was using a script like this but of course it doesnt keep the var1= bit in. Can anyone help me out here.

 $picsnumber = "variables/picsnumber.txt";
    if (file_exists($picsnumber))
    {
    $fp = fopen($picsnumber,"r+");
    $count = fgets($fp,5);
    $count += 1;
    rewind($fp);
    fputs($fp,$count,5);
    fclose($fp);  

    }
    else
    {
    $fp = fopen($picsnumber,"w");
    $count = "1";
    fputs($fp,$count,5);
    fclose($fp);
    }

thanks

What you'll need to do is actually 3 actions

1) Open the file and read in the current value of $var and close.
2) Increment $var by X
3) Open the file and set $var to be the new value that was set in step 2

The thing is that you have to remeber is that you are effectively dealing with strings when you are reading / writing to the file not actual variables
