How i can store multiple value strings in one array and call it with one variable in php? [closed]

Actually I was trying but I couldn't make it, like I want to save multiple different values in an array and call it with one variable but after calling check whether the input form value is equal as the stored value in the array.

So how can I save multiple string value in one array and can check whether the input value is the same value present in array or else it will die.

Thankyou for your help!
