$array2 = ['fruit' => 'apple',
'price' => 12.96,
'colour' => 'green'];
// Check if key exists in the associative array
echo(isset($array['foo'])); // Faster, but returns false if the value of the element is set to null
echo(array_key_exists('foo', $array)); // Slower, but returns true if the value of the element is null</lang>
