Are there any built-in PHP functions or methods that can streamline the process of mapping values based on IDs in an array?

When mapping values based on IDs in an array, you can use the array_column() function in PHP to extract a column of values based on a specific key (ID). This function simplifies the process of creating a mapping between IDs and values in an array. 

// Sample array with IDs and values
$data = [
    ['id' => 1, 'value' => 'A'],
    ['id' => 2, 'value' => 'B'],
    ['id' => 3, 'value' => 'C']
];

// Create a mapping between IDs and values
$mapping = array_column($data, 'value', 'id');

// Output the mapping
print_r($mapping);
