PHP如果字符串存在于数组中

Question

I'm having issues checking if the string exist in array after splitting a single string into array by comma. it keeps returning false here my code. Can someone tell me what I'm doing wrong in my code?

<?php

$myString = "10.0.0.1 , IP: 10.0.0.2 Date: 05/07/2017 , IP: 10.0.0.3 Date: 05/07/2017";
$IPS = explode(' , ', $myString); 
$string = "10.0.0.2 Date: 05/07/2017";

foreach ($IPS as $IP) 
{
if(in_array($string, $IP))
    {
        die('YES');
    }
    else
    {
        die('NO'); // keeps returning no when the $string is in the array.

    }
}

?>

Maybe you want to use strpos instead of looping through the array

<?php

$myString = "10.0.0.1 , IP: 10.0.0.2 Date: 05/07/2017 , IP: 10.0.0.3 Date: 05/07/2017";
$string = "10.0.0.2 Date: 05/07/2017";

if(strpos($myString, $string))
    {
        die('YES');
    }
    else
    {
        die('NO');
    } 

?>
