PHP Comparison Operators

Comparison operators, as their name implies, allow you to compare two values. You may also be interested in viewing the type comparison tables, as they show examples of various type related comparisons.

**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 <=> $b	Spaceship	An int less than, equal to, or greater than zero when `$a` is less than, equal to, or greater than `$b`, respectively.
