How can PHP's array_map function be utilized to merge two tables more efficiently and avoid potential errors in the process?

When merging two tables in PHP, the array_map function can be utilized to apply a callback function to each element of the arrays simultaneously. This can help avoid potential errors by ensuring that corresponding elements from both tables are processed together. By using array_map, we can efficiently merge the two tables without the need for nested loops or manual iteration. 

// Sample arrays representing two tables
$table1 = array('John', 'Alice', 'Bob');
$table2 = array('Doe', 'Smith', 'Johnson');

// Merge the two tables using array_map
$mergedTable = array_map(function($first, $last) {
    return $first . ' ' . $last;
}, $table1, $table2);

print_r($mergedTable);
