将数组拆分为n个数组并在php中访问各个数组

I have an array of 1000 emails.

And I want to split the array into n arrays having 45 emails in each array.

I want to separately access the splitted arrays.

How can we implement using php. I have also tried array_splice() function in php, but it returns splitted arrays, but I unable to access the splitted array.

You could use array_chunk() in this case to get batches of those emails:

$emails = array('email1', 'email2', ..... 'email1000');

// 45 each batch
$batch_emails = array_chunk($emails, 45);

foreach($batch_emails as $batch) {
    print_r($batch);
}

// or explicitly get batch/group 5
print_r($batch_emails[4]);

try this -

$f = array_chunk($yourArray, 45);
var_dump($f);

Chunks an array into arrays with size elements. The last chunk may contain less than size elements.
