Answer 1

您可以使用此live demo here。

<?php
$arrayinput = array("a","b","c","d","e");

$array = [];
foreach($arrayinput as $v)
{
  $arr = [];
  $arr[] = $v;
  if($next = next($arrayinput))
    $arr[] = $next;
  $array[] = $arr;
}
print_r($array);

这里的实例：http://sandbox.onlinephpfunctions.com/code/4de9dda457de92abdee6b4aec83b3ccff680334e

$arrayinput = array("a","b","c","d","e");
$result = [];

for ($x = 0; $x < count($arrayinput); $x+=2 ) {
    $tmp = [];
    $tmp[] = $arrayinput[$x];
    if ($x+1 < count($arrayinput)) $tmp[] = $arrayinput[$x+1];
    $result[] = $tmp;
}

var_dump($result);
