To test whether two variables are different, use any one of PHP’s many comparison operators.

<php

// define some variables
$mean   = 29;
$median = 40;
$mode   = 29;

// less-than operator
// return true if  left side is less than right
// return true here
$result = ($mean < $median);

// greater -than operator
// returns true if left side is greater than right
// return false here
$result = ($mean > $median);

// less than or equal to operator
// return true if left side is less than or equal to right
// return false here
$result =($median <= $mode);

// greater than or equal to operator
// return true if left side is greater than or equal to right
// return true here
$result = ($median >= $mode);

// equality operator
// return true if left side is equal to right
// return true here
$result = ($mean==$mode);

// not equal to operator
// return true if left side is not equal to right
// return true here
$result = ($mean != $mode);

// inequality operator
// return true if left side is not equal to right
// return true here
$result = ($mean <> $mode);
