- An array is a data structure that stores one or more similar type of values in a single value.
- Each element in the array has its own index so that it can be easily accessed.
- An array in PHP is a collection of key/value pairs.
Associate Array
- An Associative arrays are very similar to numeric arrays in term of functionality but they are different in terms of their index.
- An Associative array will have their index as string so that you can establish a strong association between key and values.
- An Associative array, each ID key is associated with a value.
- An Associative arrays we can use the values as keys and assign values to them.
