How can you efficiently handle dynamic data mapping in PHP arrays?

When dealing with dynamic data mapping in PHP arrays, one efficient way to handle it is by using a loop to iterate through the data and map it accordingly. You can create a mapping array that defines the relationship between the keys in the input data and the keys in the output data. By dynamically mapping the data based on this mapping array, you can easily handle different data structures without hardcoding specific keys. 

$inputData = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
];

$outputData = [];
$mappingArray = [
    'name' => 'full_name',
    'age' => 'user_age',
    'email' => 'user_email'
];

foreach ($mappingArray as $inputKey => $outputKey) {
    if (isset($inputData[$inputKey])) {
        $outputData[$outputKey] = $inputData[$inputKey];
    }
}

print_r($outputData);
