overwrite a line in a txt file from a form

notaloser

i want to make a script that will take information from a form and overwrite what is in a txt file. i want to do it with opening and closing times for every day of the week that i can just fill out a form and it would overwrite the old times with the new times. if anyone can help me through it, that would be great because i am lost right now and i dont know where to start.

<?
if( isset( $_POST['submit'] ) )
{
    $fp = fopen( 'times.txt' , 'w' );
    for( $i=0;$i<7;$i++ )
    {
        fwrite( $fp , $_POST['opentime'][$i].'|'.$_POST['closetime'][$i]."\n" );
    }
    fclose( $fp );

}

// times.txt contains open close times  8:00|18:00
// each line is a new day sunday = first line

$t = file( 'times.txt' );
foreach( $t as $s )
    $times[] = explode( '|' , $s );
