php arrays

在php中一次迭代数组n次,php,arrays,Php,Arrays,我有一个包含12个元素的数组，我需要一次显示4个项目 <?php $array = Array ( 0 => "ed", 1 => "smith.co.uk", 2 => "http://edsmith.co.uk/smith.jpg", 3 => "Published", 4 => "ford attenborough", 5 => "ford.co.uk", 6 => "http://f

我有一个包含12个元素的数组，我需要一次显示4个项目

<?php

$array = Array
(
    0 => "ed",
    1 => "smith.co.uk",
    2 => "http://edsmith.co.uk/smith.jpg",
    3 => "Published",
    4 => "ford attenborough",
    5 => "ford.co.uk",
    6 => "http://fordattenborough.co.uk/ford.jpg",
    7 => "Pending Approval",
    8 => "greg tolkenworth",
    9 => "greg.co.uk",
    10 => "http://greg.co.uk/greg.jpg",
    11 => "In Future"
);
foreach($array as $key => $value){
echo $value."---".$value."---".$value."---".$value."<br/><hr/>";
}
?>

我需要一次显示数组的值

，或一次显示数组的值

。

拆分数组

$newarray = array_chunk($array, 4);

foreach($newarray as $arr){
  foreach($arr as $a){
   echo $a;
  }
}

现在，

$newarray

有一个数组，每个数组中有4个项目。像这样,

$newarray = Array(
  0 => Array( 
    0 => "ed",
    1 => "smith.co.uk",
    2 => "http://edsmith.co.uk/smith.jpg",
    3 => "Published"
   ),
  1 => Array(
    0 => "ford attenborough",
    1 => "ford.co.uk",
    2 => "http://fordattenborough.co.uk/ford.jpg",
    3 => "Pending Approval"
   ),
 2 => Array(
    0 => "greg tolkenworth",
    1 => "greg.co.uk",
    2 => "http://greg.co.uk/greg.jpg",
    3 => "In Future"
   )
);

现在，您可以在

$newarray

上运行

foreach

，一次打印4个项目

foreach($newarray as $arr){
  foreach($arr as $a){
   echo $a;
  }
}

拆分阵列

$newarray = array_chunk($array, 4);

现在，

foreach($newarray as $arr){

你可以用。请参见下面的示例：

<?php
$array = Array

    9 => "greg.co.uk",
    10 => "http://greg.co.uk/greg.jpg",
    11 => "In Future"
);

while(!empty($array)) {
    $partial = array_splice($array, $i, 4);
    print_r($partial);
}

您可以使用。
请参见下面的示例：
<?php
$array = Array
