    Hello Everyone today I guide you "What is the difference between isset and array_key_exists in PHP"

    The below example helps you to differentiate between isset() and array_key_exists() . isset() will only return true or false array_key_exists() will return the key and its value 

    <?php

$newdata = array('key1' => 'Hello, 'key2' => null);

isset($newdata['key1']);             // true
array_key_exists('key1', $newdata);  // true

isset($newdata['key2']);             // false
array_key_exists('key2', $newdata);  // true

?>
    isset() v/s array_key_exists() array_key_exists() isset()
