How to Store and Retrieve Arrays in PHP Using JSON Serialization?

Storing and Retrieving Arrays in PHP

To store an array for later retrieval with PHP, you have multiple options. One efficient and flexible approach is through JSON serialization. Here's how to do it:

Storing an Array (store_array)

1. Convert the array to a JSON string using json_encode() function.
2. Save the JSON string to a file using file_put_contents().

Example:

<code class="php">$arr1 = ['a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5];
file_put_contents("array.json", json_encode($arr1));</code>

Retrieving an Array (restore_array)

1. Load the JSON string from the file using file_get_contents() function.
2. Convert the JSON string back to an array using json_decode() function.

Example:

<code class="php">$arr2 = json_decode(file_get_contents('array.json'), true);</code>

The json_encode() and json_decode() functions provide efficient and human-readable serialization of arrays, making it easy to store and retrieve arrays as needed.
