PHP compare array

Question

Is there anyway to compare arrays in php using an inbuilt function, short of doing some sort of loop?

$a1 = array(1,2,3);
$a2 = array(1,2,3);

if (array_are_         


        

Answer 1

get the array from user or input the array values.Use sort function to sort both arrays. check using ternary operator. If the both arrays are equal it will print arrays are equal else it will print arrays are not equal. there is no loop iteration here.

sort($a1);
sort($a2);
echo (($a1==$a2) ? "arrays are equal" : "arrays are not equal");
