Are there any built-in PHP functions that can be used to rename array values efficiently?

One way to efficiently rename array values in PHP is by using the array_map() function. This function allows you to apply a callback function to each element of an array and return a new array with the modified values. By defining a callback function that renames the values as needed, you can easily rename array values without needing to iterate through the array manually. 

// Define an array with values to be renamed
$originalArray = array("John" => 25, "Jane" => 30, "Alice" => 22);

// Define a callback function to rename values
function renameValues($value) {
    // Add a prefix to each value
    return "New_" . $value;
}

// Use array_map() to rename values in the original array
$renamedArray = array_map("renameValues", $originalArray);

// Output the renamed array
print_r($renamedArray);
