add timestamp to a text file

lmayer4

Morning,

I have a file that is used as an intermediary between a handheld device and SQL called upload.txt. I read somewhere that you could take a file and add a timestamp to it. I've tried but I keep getting error messages. This is what I have:

//insert into new file
$inputString = viewlog($filename);
$uploadfile = "../Upload/Upload.txt";
$setfile = $unique_id.'-'$uploadfile; //this is where I want to have
//it add the timestamp
$fp = fopen($setfile, "w+" );
$fw = fwrite( $fp, $inputString );
fclose( $fp);

Any thoughts would be greatly appreciated.

I'm not sure what you're trying to do with these lines:

$uploadfile = "../Upload/Upload.txt"; 
$setfile = $unique_id.'-'$uploadfile;

At any rate, you should be getting a parse error with that second line. This would be valid:

$setfile = $unique_id . '-' . $uploadfile;

although I'm not sure it would produce what you want.

If you want the timestamp at the beginning of the file you're writing to, you could do it like this:

$fw = fwrite($fp, time() . $inputString);

Wait, are you trying to insert a timestamp into the text of a file, or are you trying to change the mtime/ctime/atime of a file (modified time, created time, accessed time)?

Thanks everyone...

Heres how I ended up doing it:

//insert into new file
$uploadpath = '/Upload/';
$inputString = viewlog($filename);
$uploadfile = "Upload";
$setpath = $uploaddir.$uploadfile;
$setfile = $setpath.$unique_id.'.txt'; ;
$fp = fopen($setfile, "w+" );
$fw = fwrite( $fp, $inputString );
fclose( $fp);

Whatever works 🙂
