How can you ensure that each row in a database table receives a unique value from an array when using the UPDATE statement in PHP?

When updating rows in a database table using an array of values in PHP, you can ensure that each row receives a unique value by generating a unique identifier for each row before updating. One way to achieve this is by using a loop to iterate through the array and assign a unique value to each row before executing the UPDATE statement. 

<?php

// Sample array of values
$array = ['value1', 'value2', 'value3'];

// Generate a unique identifier for each row
foreach ($array as $key => $value) {
    $uniqueValue = uniqid();
    
    // Update the row in the database table with the unique value
    $query = "UPDATE table_name SET column_name = '$uniqueValue' WHERE id = $key";
    // Execute the query
}

?>
