I am just making sure I understand this correctly. "=" is only to be used when assigning value, whereas "==" is used to check if something equals another thing? Is this correct?

When you asigned something like
$a = 1; then

echo $a displays 1

however you use == in statements to compair

exmaple

If ($a == 1) {
  echo 'Statement is true';
} else {
  echo 'Statement is false';
}


So yes you are correct.

And just to throw a little more confusion in,
== means compare the values.  Variables will be cast to the relevant type.  (8 == '8') returns true.
=== means compare the values and types.  No casting occurs.  (8 === '8') returns false.
