I have been working on a project using PHP and I came across a function called "array_key_exists()". I read the PHP documentation but I'm still a bit confused about how it works exactly. I was hoping someone could provide me with a clear explanation and maybe even an example.
From what I understand, the function "array_key_exists()" is used to check if a specified key or index exists in an array. Is that correct? Can someone explain how I can use it in PHP?
I would really appreciate it if someone could provide me with an example code snippet to demonstrate the usage of this function. It would help me understand it better and see it in action.
Thank you so much in advance for your help!
