Php array operator

Description:

Is the way to manipulate an array.

In fact, there are only three: joint (+) equals (= =, = =) does not equal (! =,! =)

Join: merge the second array into the first array. But if the subscript of the second array is equal to the first array, it cannot be merged and will be overwritten by the first.

/ / the array operator / + combines $arr1 = array; $arr2 = array (5 = > 6 pairings); var_dump ($arr1+$arr2); / / = = key-value pairs equivalent $arr1 = array (1pairwise 2pint 3pint 4pint 5); $arr2 = array ('1pint paircase 2pint 3pint 4pint 5); if ($arr1 = = $arr2) {echo "equivalence"; / / output equivalence} / / = key-value pair equality, type if ($arr1 = $arr2) {echo "equivalence" } Thank you for reading!
