How can one effectively manage memory usage when handling large amounts of data in PHP arrays?

When handling large amounts of data in PHP arrays, it's important to manage memory usage efficiently to prevent performance issues and potential crashes. One way to do this is by using generators in PHP, which allow you to process data in smaller chunks instead of loading everything into memory at once. By using generators, you can iterate over the data without storing it all in memory, thus reducing memory usage significantly. 

// Example of using a generator to process large amounts of data efficiently
function largeDataGenerator($data) {
    foreach ($data as $item) {
        yield $item;
    }
}

// Usage example
$largeData = range(1, 1000000); // Generating large data set
$generator = largeDataGenerator($largeData);

foreach ($generator as $item) {
    // Process each item without storing all data in memory
    echo $item . "\n";
}
