按字符串名称构建数组或按字符串值创建多个数组

Question

我想通过打破主数组来构建一个数组或多个数组，我的数组就像，

    Array
(
    [0] => string1   
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 66
    [5] => 34
    [6] => string1
    [7] => aww
    [8] => brr
    [9] => string3
    [10] => xas

)

所以基本上根据值 'string1' 我想创建一个 新数组或第一个数组 其中有只有这三个值（1,2,3）和string2和string3相同，所以每个数组都有它的价值观（三）。请帮我建立这个。 注意：所有字符串名称都是静态的。

提前谢谢你。

我喜欢的结果：

string1 array:  
<pre>Array
(
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 66
    [5] => 34
)

string2 array:  
<pre>Array
(
    [1] => aww
    [2] => brr
)

string3 array:  
<pre>Array
(
    [1] => xas
)

我想这会让你得到你想要的。

It does assume that the first entry in the old array will be a keyword!

$old = array('string1',1,2,3,66,34,'string2','aww','brr','string3','xas');
$new = array();

$keywords = array('string1', 'string2', 'string3');
$last_keyword = '';

foreach ($old as $o) {
    if ( in_array($o, $keywords) ) {
        $last_keyword = $o;        
    } else {
        $new[$last_keyword][] = $o;
    }
}

print_r($new);

它会像这样创建一个新数组

Array
(
    [string1] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
            [3] => 66
            [4] => 34
        )

    [string2] => Array
        (
            [0] => aww
            [1] => brr
        )

    [string3] => Array
        (
            [0] => xas
        )

)

However I still maintain that it would be better to go back to where the original array gets created and look to amend that process rather than write a fixup for it

按字符串名称构建数组或按字符串值创建多个数组

Build array by string name OR make multiple array by string values

php

arrays

string

multidimensional-array

array-push
