Match a string in an array strpos(): Empty needle

Question

I have a string from database that I want to match with an array but it results in error saying:

strpos(): Empty needle in line X

if (!isset($_SESSION['arry'])) {

    $_SESSION['arry'] = array();

}

$imp = 42;

$arrys =  $_SESSION['arry'];



foreach($arrys as $string)

{

  if(strpos($imp, $string) !== false) 

  {

    $pow =1;

    break;

  }

}



if($pow==1){ exit; }

The array looks like this:

Array

(

    [0] => 218

    [1] => 219

    [2] =>  218

    [3] => 220

    [4] => 222

    [5] =>  42

    [6] => 223

)

Answer 1

You are doing the opposite way , searching string in 42 , instead go for

strpos($string, $imp)

and as @abracadaver added you can use in_array

TRY THIS : (updated)

foreach($arrys as $string)
{
  if(strpos($string, $imp) !== FALSE) 
  {
    $pow =1;
    break;
  }
}
