PHP块数组成批 [英] php chunk arrays into batches

问题描述

我有一个要发送给API的具有400个(但可以是任何名称)名称的数组，但是API每次最多只能接收200个请求，我该如何对数组进行分块，以便每200个项目，我要执行操作吗?

I have an array with say 400 (but could be anything) names i want to send to an API, but the API only receives a max of 200 requests per time, how do i chunk my array so that for every 200th item, i perform an action?

这是我到目前为止所拥有的，而不是发出我的API请求，我只是试图将数组的输出到页面上.

Here's what i have so far, rather than making my API request, i'm just trying to output the array's to the page.

<?php

for ($i = 0; $i <= $smsListLimit; $i++)
    {
    if ($i <= 199)
        {
        array_push($newarray, $smsList[$i]);
        if ($i == 199)
            {
            echo " < pre > ";
            var_dump($newarray);
            echo " < / pre > ";
            echo "!!!!!!!BREAK!!!!!!!";
            }
        }
    elseif ($i > 199 && $i <= 399)
        {
        unset($newarray);
        array_push($newarray, $smsList[$i]);
        if ($i == $smsListLimit)
            {
            echo " < pre > ";
            var_dump($newarray);
            echo " < / pre > ";
            echo "!!!!!!!BREAK!!!!!!!";
            }
        }
    }

die();
?>

这会将前200个返回数组，但不返回其余数组-但是不管传入的数组是否为5000，我都不必为每个200写一个大型if语句.

This returns the first 200 into an array, but not the remainder - but regardless, if the incoming array was 5000, i don't want to have to write a massive if statement for every 200.

有人提供任何建议吗?

推荐答案

您将使用array_chunk: http://php.net/manual/en/function.array-chunk.php

You'd use array_chunk: http://php.net/manual/en/function.array-chunk.php

exe.

$input_array = array('a', 'b', 'c', 'd', 'e');
print_r(array_chunk($input_array, 2));

结果:

 Array
(
    [0] => Array
        (
            [0] => a
            [1] => b
        )

    [1] => Array
        (
            [0] => c
            [1] => d
        )

    [2] => Array
        (
            [0] => e
        )

)
