erasing data

[Anon]

Hi,

 Well, I am doing my best to erase all the data in the open file. Before writing to the file I want it to be cleared, with no adittional data.

I do like this:

<?php
fopen ($f_handler);
...
fwrite ($f_handler, $myString);
fclose ($f_handler);
?>

So before writing to the file I need to erase all the data it contains.

Thank You !

If you use
$fp = fopen($file_to_write_to,"w");

It will place the file pointer at the beginning, so all of the data already inside the file will be written over.

$fp = fopen($file_to_write_to,"w");
fwrite($fp,"New stuff in file!");
fclose($fp);
