Reset keys of array elements in php

本文关键字：数组元素 php | 更新日期: 2023-09-27

我想重置上面的内容，如下所示。

$_REQUEST['some_number'] => Array
(
            [0] => 1
            [0_1] => 2
            [0_2] => 3
            [2] => 7
            [2_1] => 8
             [3] => 9
            [3_1] => 10
)

至

$_REQUEST['some_number'] => Array
(
            [0] => 1
            [0_1] => 2
            [0_2] => 3
            [1] => 7
            [1_1] => 8
            [2] => 9
            [2_1] => 10
)

我为使用了array_values

print_r(array_values($_REQUEST['some_number']))；

我得到

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 7
    [4] => 8
)

我想你是在问这个

$samp = array("0" => 1,
              "0_1" => 2,
              "0_2" => 3,
              "2" => 7,
              "2_1" => 8,
              "3" => 9,
              "3_1" => 10 );

$samp2 = $samp;
$i=0;
$j=0;
$samp = array();
    foreach($samp2 as $values)
    {
        if($j != 0)
        $samp[$i."_".$j] = $values;
        else
        $samp[$i] = $values; 
        if($j > 1)
        {
            $i++;
            $j=0;
        }
        else
         $j++;
    }
print_r($samp);
