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);

活生生的例子在這裏：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);
