PHP Array Operators $a + $b Union of Joint $a and $b.$a = = $b equal if the $a and $b have the same key/value pairs true.$a = = = $b congruent if $a and $b have the same key/value pairs and the order and type are the same, TRUE.$a! = $b is TRUE if the $a does not equal $b.$a $a!== $b Not equal to TRUE if the $a is not all equals $b. The only one array operator in PHP is the + operator. It appends the right array to the left array, but the duplicate k
