Question

Is there a specific way to check for a specific integer within a switch statment.

For example.

$user = $ads[$i]->from_user;

To check for the number 2 as $i in the above expression.

Answer 1

You can check like:

if ($ads[$i] === 2)
{
 // code here
}

Or if you meant alone, you can do:

if ($i === 2)
{
 // code here
}

If the number in string representation (type), you should use == rather than ===.

If however you meant whether 2 is present in the array $ads:

if (in_array(2, $ads))
{
 // 2 found in $ads array
}
