Array operation operators in php

Array operator operator

Example results + union of $a + $bachela and $b. = = equal $a = = $b true if $an and $b have the same key / value pair. = = congruent $a = = $b true if $an and $b have the same key / value pair and the order and type are the same. ! = unequal $a! = $b true if $an is not equal to $b. Unequal $a $b is true if $an is not equal to $b. ! = incongruent $a! = $b is true if not all $an is equal to $b.

1. + operator

The + operator appends the array element on the right to the array on the left, and if the key is the same, the previous array value will overwrite the following array value.

2. Comparison operator

= = (equal to), = = (always equal to), (not equal to),! = (not equal to),! = (incomplete, etc.)

Cells in an array are equal when compared if they have the same key name and value.
