Code:

$issuperpage = strpos($content, '$$$superpage$$$');
    if ($issuperpage === false)
    {
      echo 'equals three';
    }

Code:

$issuperpage = strpos($content, '$$$superpage$$$');
    if ($issuperpage == false)
    {
      echo 'equals two';
    }

What is the difference between triple equals and double equals and single equals for that matter?

[Bompa]

The equals sign ASSIGNS a value to a variable name.

The double and triple do comparisons:

[ehlo]

== tests that the values are equal, while === tests that the value and the type are the same.

[perkiset]

it's commonly known as exactly equal as opposed to equal value. Like ehlo said above, that means types as well as value.

[nutballs]

triple is when things are so freakin equal, that double equal, let alone plain old equal dont do it justice.

"that forgery is fucking triple equal the original!"

1 == '1' will evaluate TRUE
1 === '1' will evalutate FALSE
