PHP preg_split 仅在双引号内

Question

如何使用 preg_split 函数

仅获取双引号内的值

来自这个示例字符串

$String = '["number","1","2470A K18-901","PEDAL ASSY, GEAR CHANGE","1","PCS","56500.00","0","56500","action"]'

变成这样：

Array
(
    [0] => number
    [1] => 1
    [2] => 2470A K18-901
    [3] => PEDAL ASSY, GEAR CHANGE
    [4] => 1
    [5] => PCS
    [6] => 56500.00
    [7] => 0
    [8] => 56500
    [9] => action
)

或者用另一个函数来实现

Answer 1

如果您希望拆分的值实际上是字符串类型（如您的问题所示），您可以使用 preg_match_all 代替（preg_match_all 基本上是一个行来匹配所有必需的值；使用 preg_split 你必须 trim 值周围的括号）。

<?php

$String = '["number","1","2470A K18-901","PEDAL ASSY, GEAR CHANGE","1","PCS","56500.00","0","56500","action"]';
preg_match_all('/(?<=,"|\[")[^"]+?(?=")/', $String, $Match);
$Result = $Match[0];

var_dump($Result);

PS：此解决方案假定数组 中的值没有任何转义引号 .

Answer 2

如果要将字符串转换为数组，请使用 json_decode:

   <?php
   $jsonobj = '["number","1","2470A K18-901","PEDAL ASSY, GEAR 
   CHANGE","1","PCS","56500.00","0","56500","action"]';

   print_r(json_decode($jsonobj));
   ?>

输出：

Array ( [0] => number [1] => 1 [2] => 2470A K18-901 [3] => PEDAL ASSY, GEAR CHANGE [4] => 1 [5] => PCS [6] => 56500.00 [7] => 0 [8] => 56500 [9] => 动作)

Answer 3

这是一个 JSON 字符串，您可以使用 json_decode() 函数将其转换为数组。 https://www.php.net/manual/de/function.json-decode.php

<?php
$String = '["number","1","2470A K18-901","PEDAL ASSY, GEAR CHANGE","1","PCS","56500.00","0","56500","action"]';

print_r(json_decode($String));

PHP preg_split 仅在双引号内

PHP preg_split only inside double quotes
