How can the use of array_map in PHP be beneficial in situations where array_walk is causing errors related to datatype?

When array_walk is causing errors related to datatype mismatches, using array_map can be beneficial as it allows for more control over the data transformation process. Array_map applies a callback function to each element of an array, allowing for type conversions or manipulations before processing the data. This can help avoid errors related to datatype mismatches that may occur with array_walk. 

// Example of using array_map to handle datatype mismatches
$array = [1, 2, 3, 4, 5];

// Convert all elements to strings
$array = array_map('strval', $array);

// Output the modified array
print_r($array);
