How can the use of array_map() and strtr() help in replacing values in arrays in PHP?

When we need to replace values in arrays in PHP, we can use array_map() to apply a callback function to each element of the array and strtr() to replace specific values within a string. By combining these functions, we can easily iterate over an array, replace the desired values, and return the updated array with the replacements. 

// Original array with values to be replaced
$originalArray = array("apple", "banana", "cherry");

// Define a function to replace values
function replaceValues($value) {
    return strtr($value, array('apple' => 'orange', 'banana' => 'pear'));
}

// Use array_map() to apply the function to each element in the array
$updatedArray = array_map('replaceValues', $originalArray);

// Output the updated array
print_r($updatedArray);
