$filename = '/path/to/file.txt';

$contents = file_get_contents($filename);
$contents = str_replace($search,$replace,$contents);

$handle = fopen($filename, "w");
if (fwrite($handle, $contents)) {
   echo 'file write successful';
} else {
   echo 'file write failed';
   exit;
}
fclose($handle);

also - there's no need to enclose the variable $file
in quotes here:
> $fp = fopen("$file", "w+");
