How can I convert an array of objects to an associative array in PHP?

To convert an array of objects to an associative array in PHP, you can use the array_column function to extract the values from the objects, and then use the array_combine function to create the associative array.

Here is an example of how you can use these functions to convert an array of objects to an associative array:

<?php

// An array of objects
$objects = [
  (object) ['id' => 1, 'name' => 'Alice'],
  (object) ['id' => 2, 'name' => 'Bob'],
  (object) ['id' => 3, 'name' => 'Charlie'],
];

// Extract the values from the objects
$ids = array_column($objects, 'id');
$names = array_column($objects, 'name');

// Create the associative array
$associativeArray = array_combine($ids, $names);

print_r($associativeArray);

This code will output the following associative array:

Array (
  [1] => Alice
  [2] => Bob
  [3] => Charlie
)

I hope this helps! Let me know if you have any questions or need more information.
