如何使用PHP将数组分解为另一个数组而不是子数组？

问题描述：

Is there any possibility to explode values of an array to create direct a new array with these values. I'm able to do this only with a intemidiate step.

I have following array:

Array (
[0] => OtherMachines, Polymers
[1] => Engines/Pumps/Turbines, Measurement
[2] => Materials/Metallurgy
[3] => Materials/Metallurgy, ThermProcesses
)

Then I explode its values:

foreach ($array00 as $v) {
    $array01 = explode(", ", $v);
}

and receive following array:

Array
(
[0] => Array
    (
        [0] => OtherMachines
        [1] => Polymers
    )

[1] => Array
    (
        [0] => Engines/Pumps/Turbines
        [1] => Measurement
    )

[2] => Array
    (
        [0] => Materials/Metallurgy
    )

[3] => Array
    (
        [0] => Materials/Metallurgy
        [1] => ThermProcesses
    )
)

Than I have to flatten the array to get the one I wish:

// Flatten the array.
$array02 = call_user_func_array('array_merge', $array01);

Final result:

Array (
[0] => OtherMachines
[1] => Polymers
[2] => Engines/Pumps/Turbines
[3] => Measurement
[4] => Materials/Metallurgy
[5] => Materials/Metallurgy
[6] => ThermProcesses
)

Is there any way to do this direct?

Many thanks in advance.

是否有可能爆炸数组的值来创建具有这些值的新数组。我只能通过一个intemidiate步骤来做到这一点。 p>

我有以下数组： p>

 数组（
 [0]  =＆gt; OtherMachines，Polymers 
 [1] =＆gt;发动机/泵/涡轮机，Measurement 
 [2] =＆gt;材料/冶金
 [3] =＆gt;材料/冶金，ThermProcesses 
）
   code>  pre> 
 
 然后我将其值分解： p> 
 
 
  foreach（$ array00 as $ v）{
 $ array01 = explode  （“，”，$ v）; 
} 
  code>  pre> 
 
 并接收以下数组： p> 
 
 
  Array \  n（
 [0] =＆gt;数组
（
 [0] =＆gt; OtherMachines 
 [1] =＆gt;聚合物
）
 
 [1] =＆gt;数组
（\  n [0] =＆gt;发动机/泵/涡轮机
 [1] =＆gt;测量
）
 
 [2] =＆gt;数组
（
 [0] =＆gt;材料/冶金\  n）
 
 [3] =＆gt;数组
（
 [0] =＆gt;材料/冶金
 [1] =＆gt; ThermProcesses 
）
）
  code>   pre> 
 
 我必须将数组展平以获得我想要的数组： p> 
 
 
  //展平数组。
 $ array02 = call_us  er_func_array（'array_merge'，$ array01）; 
  code>  pre> 
 
 最终结果： p> 
 
 
  Array（
 [0  ] =＆gt;  OtherMachines 
 [1] =＆gt; 聚合物
 [2] =＆gt; 发动机/泵/涡轮机
 [3] =＆gt; 测量
 [4] =＆gt; 材料/冶金
 [5] =＆gt; 材料/冶金
 [6] =＆gt;  ThermProcesses 
）
  code>  pre> 
 
 有没有办法直接这样做？ p> 
 
 
非常感谢提前。 p>

答

Yes, just implode it and then explode.

$result = explode(', ', implode(', ', $array));

答

$arr = array (
    'OtherMachines, Polymers',
    'Engines/Pumps/Turbines, Measurement',
    'Materials/Metallurgy',
    'Materials/Metallurgy, ThermProcesses'
);

print_r(array_map('trim', explode(',', implode(',', $arr))));

Array
(
    [0] => OtherMachines
    [1] => Polymers
    [2] => Engines/Pumps/Turbines
    [3] => Measurement
    [4] => Materials/Metallurgy
    [5] => Materials/Metallurgy
    [6] => ThermProcesses
)

Or simply:

$arr = array (
    'OtherMachines, Polymers',
    'Engines/Pumps/Turbines, Measurement',
    'Materials/Metallurgy',
    'Materials/Metallurgy, ThermProcesses'
);

print_r(explode(', ', implode(', ', $arr)));
