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!";
}

Please trim the values and then check against "Banana"

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!";
}

Or $array = explode(" : ", $var);

Yes @RiggsFolly You should post that as an answer. Way simpler

No actually I think your method s more reliable. In case they get $var = "Apple : Banana:Orange"; as a string

Well, now I just feel dumb :) Thank you so much tho! I also recommend anyone doing this to store each trimmed value in new variable: $value_a = trim($array[0]); $value_b = trim($array[1]);

Your condition doesn't work because each element of array has space. You should remove excess spaces. You can use trim function to remove spaces and array_map function to apply trim in each element of the array. For example:

$var = "Apple : Banana";
$array = array_map('trim', explode(":", $var));
if ($array[1] == "Banana") {
  echo "Banana!";
}

result:

Banana!

You can do it by using preg_split and regex

$parts = preg_split('/\s+\:\s+/', $var);

Then on $parts you will get:

array(2) { [0]=> string(5) "Apple" [1]=> string(6) "Banana" }
