Question

i have an Array, when i print it i get the following output;

Array[{"city":"London","school":"st patrick"}]

Now i want to read the item saved in variable city and check if its London in the IF condition below;

if ($cityArray['city'] == 'London') {

  echo 'City present';
}

My if condition above, is incorrect, i am not getting the expected output. I guess the way i am accessing the city item is incorrect.

A couple of things. Your array looks to be JSON format. You’ll want to decode using json_decode (after fixing the format of the array):

$jsonArray = Array('{"city":"London","school":"st patrick"}'); // User the correct PHP array format: Array() while the inside elements should be quoted if they're strings.
$cityArray = json_decode($jsonArray[0]);

Use the correct variable reference format:

if ($cityArray->city == 'London') { // $cityArray is an object, so you'll need to use the -> operator to get its "city" property.
    echo 'City present';
}

The way you’re trying to access the value of the associative array (by inputting the name to return the value) is correct, but just need to fix a couple of formatting issues, is all.

Edit: Added index number of array to get the JSON.
