I need a very simple piece of php code that does the following:

INPUT: a string - let's say $a

1. open a .txt file, check if the file already contains a line that equals $a and if so echo on the screen "contains $a"
2. if not, add $a to the end of the file on a new line

Thanks!

$string = '$a';

$file = file [uk2.php.net]('file.txt');

if (in_array [uk2.php.net]($string,$file))
{
// exists
}
else
{
$fp = fopen [uk3.php.net]('file.txt', 'ab');

if ($fp)
{
fwrite [uk3.php.net]($fp,$string);
fclose [uk3.php.net]($fp);
}
}

Not tested, but should give you some pointers.
