php一次处理50个数组元素并在完成后删除它们

Question

I have an array of 100 links (each array element is a link) and I want to process to 5 at a time. I was thinking of using array_slice() to achieve this however once the first 5 elements are processed I want to remove them from my array so only the unprocessed links to remain in it until all the elements are processes and array becomes empty.

My code looks like this:

$links = array("http://www.example.com", "http://www.example.com", "http://www.example.com", "http://www.example.com", "http://www.example.com", "http://www.example.com", "http://www.example.com", "http://www.example.com", "http://www.example.com");

$first_five = array_slice($links, 0, 5);

foreach($first_five as $ff) {
process_link($ff);
}

// so far so good but how do I remove the processed elements and process the remaining onces until $links[] is empty? ?>

Answer 1

array_chunk() might be what you're looking for. It splits the given array into an array of arrays, each containing the specified number of elements:

foreach (array_chunk($links, 5) as $slice) {
    // $slice is an array containing 5 elements
    // process it further
}
