如何检查两个阵列是否具有相同的元素而不管它们的索引位置

Question

can you please let me know how I can check if two arrays have same elements and return true or false regardless of their elements index position? as you can see the $a==$b is not doing this

$a = array("apple","banana", "strawberry");
$b = array("strawberry", "apple","banana");
if($a==$b){
   echo "yes";
}else{
 echo "no";
}

Use Array Diff :

$a = array("apple","banana", "strawberry");
$b = array("strawberry", "apple","banana");


$result = array_diff($a, $b);

if(count($result) > 0){
   echo "yes";
}else{
   echo "no";
}
