I have a question regarding the `array_key_exists` function in PHP and its usage with regular expressions. I'm currently working on a project where I need to check if a specific key exists in an array but the key's name is dynamic and can have a pattern associated with it.
For example, let's say I have an array that looks like this:
$myArray = [
'element123' => 'Value 1',
'element456' => 'Value 2',
'element789' => 'Value 3'
I want to use a regular expression to check if a key exists in the array that follows a specific pattern, like "element\d+". So, if I use `array_key_exists('element\d+', $myArray)`, I want it to return true if `element123`, `element456`, or any other key that matches the pattern is present in the array.
I've tried using the `array_key_exists` function directly with a regular expression pattern, but it doesn't seem to work. Do I need to use a different function or approach to achieve this?
Any help or guidance on this issue would be greatly appreciated. Thank you in advance!
