Question:-

What is the differences between $a != $b and $a !== $b?

Answer:-

Comparison Operators
Example	Name	Result
$a == $b	Equal	`TRUE` if `$a` is equal to `$b` after type juggling.
$a === $b	Identical	`TRUE` if `$a` is equal to `$b`, and they are of the same type.
$a != $b	Not equal	`TRUE` if `$a` is not equal to `$b` after type juggling.
$a <> $b	Not equal	`TRUE` if `$a` is not equal to `$b` after type juggling.
$a !== $b	Not identical	`TRUE` if `$a` is not equal to `$b`, or they are not of the same type.
$a < $b	Less than	`TRUE` if `$a` is strictly less than `$b`.
$a > $b	Greater than	`TRUE` if `$a` is strictly greater than `$b`.
$a <= $b	Less than or equal to	`TRUE` if `$a` is less than or equal to `$b`.
$a >= $b	Greater than or equal to	`TRUE` if `$a` is greater than or equal to `$b`.
$a <=> $b	Spaceship	An integer less than, equal to, or greater than zero when `$a` is respectively less than, equal to, or greater than `$b`. Available as of PHP 7.

!= means inequality (TRUE if $a is not equal to $b) and !== means non-identity (TRUE if $a is not identical to $b).
