What potential issues can arise when working with large arrays in PHP?

One potential issue when working with large arrays in PHP is running out of memory due to the size of the array. To solve this issue, you can use generators instead of arrays to iterate over large datasets without loading the entire dataset into memory at once. 

function largeArrayGenerator($data) {
    foreach ($data as $item) {
        yield $item;
    }
}

$largeData = range(1, 1000000); // Example large dataset
$generator = largeArrayGenerator($largeData);

foreach ($generator as $item) {
    // Process each item without loading the entire dataset into memory
}
