[PHP] Deleting a String from a file.

[Cameron Badgley]

Hey, I'm trying to write a script which deletes a String from a file. The 
String that the user wants deleted is provided from a form and the file is 
named to2do.txt. I have a hidden variable called "deleting" that lets me 
know when the string has been submitted.

I have written the following code but receive the error:
Warning: fclose(): supplied argument is not a valid File-Handle resource in 
/u3/7/cirop27/public_html/todo/to2doDEL.php on line 63

Code below:

if($_POST['deleting']=='true'){

       //grab info from post array
       $msg = $_POST['deleteThis'];
       //when the string was written to the file, this replace occured. it 
is repeated here
       //for consistency
       $msg = str_replace( "\n" , "<br>", $msg);

       //open msg file for read/write
       $mfile = fopen("to2do.txt",'r+');
       //delete the string
       $mfile = str_replace($msg, "", $mfile);
       /*** error occurs here ***/
       fclose($mfile);
}

to2do.txt is a valid file, as I was able to write to it and can view its 
contents.
Can anyone tell me if I am going about this the wrong way? Thanks for any 
help.
