如何字符串转换为数组？ [英] How to convert string to array?

问题描述

我需要转换的字符串

 名称1，B，2，NAME2，C，3，NAME3，B，2，.. ..
 

像数组

  $改编[0] ['名'] =名称1;
$常用3 [0] ['字符'] =B;
$常用3 [0] [QNT'] =2;$常用3 [1] ['名'] =NAME2;
$常用3 [1] ['字符'] =C;
$常用3 [1] ['QNT'] =3;$常用3 [2] ['名'] =NAME3;
$常用3 [2] ['字符'] =b的;
$常用3 [2] ['QNT'] =2;
 

我用爆炸提取一个字符串数组，但它不能正常工作

任何想法？

解决方案

  $输入='名称1，B，2，NAME2，C， 3，NAME3，b，2';
$输入= str_replace函数（''，''，$输入）;
$输入=爆炸（''，$输入）;$输出=阵列（）;
$ I = 0;
而（$ I＆LT;计数（$输入））{
    $输出[] =数组（
        '名'=＆GT; $输入[$ i ++在]
        '字符'= GT; $输入[$ i ++在]
        QNT'=＆GT; $输入[$ I ++]
    ）;
}的print_r（$输出）;
 

输出：

 阵列
（
    [0] =＆GT;排列
        （
            [名] =＆GT;名1
            [字符] =＆GT; b
            [QNT] =＆GT; 2
        ）    [1] =＆GT;排列
        （
            [名] =＆GT; NAME2
            [字符] =＆GT; C
            [QNT] =＆GT; 3
        ）    [2] =＆GT;排列
        （
            [名] =＆GT; NAME3
            [字符] =＆GT; b
            [QNT] =＆GT; 2
        ））
 

I need to convert string

"name1", "b", "2", "name2", "c", "3", "name3", "b", "2", ....

to an array like

$arr[0]['name'] = "name1";
$arr[0]['char'] = "b";
$arr[0]['qnt'] = "2";

$arr[1]['name'] = "name2";
$arr[1]['char'] = "c";
$arr[1]['qnt'] = "3";

$arr[2]['name'] = "name3";
$arr[2]['char'] = "b";
$arr[2]['qnt'] = "2";

I used explode to extract an string to array but it not work

Any idea?

解决方案

$input = '"name1", "b", "2", "name2", "c", "3", "name3", "b", "2"';
$input = str_replace('"', '', $input);
$input = explode(', ', $input);

$output = array();
$i = 0;
while ($i < count($input)) {
    $output[] = array(
        'name' => $input[$i++],
        'char' => $input[$i++],
        'qnt' => $input[$i++]
    );
}

print_r($output);

Output:

Array
(
    [0] => Array
        (
            [name] => name1
            [char] => b
            [qnt] => 2
        )

    [1] => Array
        (
            [name] => name2
            [char] => c
            [qnt] => 3
        )

    [2] => Array
        (
            [name] => name3
            [char] => b
            [qnt] => 2
        )

)
