PHP: Check if array key is specific string

Question

I'm trying to create an if statement. based on the string of the

$var = "Apple : Banana";
$array = explode(":", $var);
print_r($array); //array([0] => 'Apple' [1] => 'Banana')

if ($array[1] == "Banana") {
  echo "Banana!";
}

Answer 1

The string has space before and after :, so array will be

array(2) { 
    [0]=> string(6) "Apple " 
    [1]=> string(7) " Banana" 
}

You need to remove space from items using trim() and then compare it.

$var = "Apple : Banana";
$array = explode(":", $var);

if (trim($array[1]) == "Banana") {
    echo "Banana!";
}
