Use this
$a = array(0, 3);
$b = array(0 => 'image', 1 => 'profile', 2 => 'password', 3 => 'login');
$c = array_intersect_key($b, array_flip($a));
Results
Array
(
[0] => image
[3] => login
)

Use inarray into foreach
<?php
$a = array(0,3);
$b= array('image','profile','password','login');
foreach($b as $key=>$value){
if(in_array($key, $a)) {
echo $value."<br>";
}
}
?>
Output
image
login

try array_intersect
array_intersect($a,$b);
or try === operator to compare the value in the array
<?php
$a=array(0,3);
$b=array(image,password);
foreach($a as $k=>$v){
if($a[$k]===$b[$k]){
echo "$k index is Same<br>";
}else{
echo "$k index is different<br>";
}
}
output
0 index is different
1 index is different
