Writing To Files In PHP

[rapmonkey]

I have a form that a user fills out, with one text box. I want everything in that text box, which is sent as a variable to a php file, fully REPLACE the contents of a text file. In other words, I want the variable to edit the text file by erasing the contents of the file, and replacing it with the variable's contents. How would I do this? I know it involvse fopen() and fwrite() but I don't know how to code it.

Basically

if( $fp = fopen( 'file.txt' , 'w' ) )
{
    fwrite( $fp , $variable );
    fclose( $fp );
}
else
    echo "Could not open th file for writing";

That half-way works. It opens the file and erases its content, but doesn't replace it with the new content, so the file ends up blank. 🙁

You have to change $variable to whatever variable has the content.
