Empty a file ... 1

[dbeezzz]

Is there any way to empty a file in php. Bascially I open a file and read in some values, then I feed the file into another function. I want to empty the file again for the next time.

There doesn't seem to be much functionality to fwrite() ? It doesn't give me the option of writing over the previous file contents.

$filename = './templates/Classic/pad.tpl';
 $fp = fopen($filename, "a");
 flock($fp, LOCK_EX);
 $string = $output;
 if ( !fputs($fp, $string) ) { die("There was an error writing to the file 1"); } 
 $template->set_filenames( array('fckeditor' => './templates/Classic/pad.tpl') );
 if ( !fwrite($fp, ' ') ) { die("There was an error writing to the file 2"); }
 
 flock($fp, LOCK_UN);
 fclose($fp);

Thanks

It all depends on what mode you use in fopen().

In the code above you are using 'a' which is used when you want to append the file contents. You will probably want to use 'w' or 'w+'. Both of these place the file pointer at the beginning of the file and truncate the file length to zero (erase the contents, in a sense). The 'w+' is used when you want to read and write to the file. 'w' is used when you only want to write to the file.

Thanks Itshim,
I should have noticed, I thought the fopen( a ) referred was a reference to 'all'.
