How can you efficiently extract and process 100 entries at a time from a large comma-separated list in PHP?

To efficiently extract and process 100 entries at a time from a large comma-separated list in PHP, you can use the explode() function to split the list into an array, then use array_chunk() to divide the array into chunks of 100 entries each. You can then loop through each chunk and process the entries as needed.

// Large comma-separated list
$list = "entry1,entry2,entry3,...";

// Split the list into an array
$entries = explode(",", $list);

// Divide the array into chunks of 100 entries each
$chunks = array_chunk($entries, 100);

// Loop through each chunk and process the entries
foreach ($chunks as $chunk) {
    foreach ($chunk as $entry) {
        // Process each entry here
    }
}
