PHP array_chunk - 斯普利特基于变 [英] PHP array_chunk - split based on variable

问题描述

是否有可能 array_chunk 基于阵列内的值？

阵列

 阵列（
[4f5hfgb] =＆GT;阵列（
[0] =＆GT; ACME
[1] =＆GT; 4f5hfgb
[2] =＆GT;阿伯丁
）
[sdf4ws] =＆GT;阵列（
[0] =＆GT; ACME
[1] =＆GT; sdf4ws
[2] =＆GT;伯明翰
）
[dfgdfg54] =＆GT;阵列（
[0] =＆GT; EDNON
[1] =＆GT; dfgdfg54
[2] =＆GT;伯明翰
）
[345bfg] =＆GT;阵列（
[0] =＆GT; EDNON
[1] =＆GT; 345bfg
[2] =＆GT;伯明翰
）
[345fgfd] =＆GT;阵列（
[0] =＆GT;阀
[1] =＆GT; 345fgfd
[2] =＆GT;伯明翰
）
）
 

是否有可能块那些具有相同值 [0] ？

所需的输出

 阵列（
    [4f5hfgb] =＆GT;阵列（
    [0] =＆GT; ACME
    [1] =＆GT; 4f5hfgb
    [2] =＆GT;阿伯丁
    ）
    [sdf4ws] =＆GT;阵列（
    [0] =＆GT; ACME
    [1] =＆GT; sdf4ws
    [2] =＆GT;伯明翰
    ）
）阵列（
    [dfgdfg54] =＆GT;阵列（
    [0] =＆GT; EDNON
    [1] =＆GT; dfgdfg54
    [2] =＆GT;伯明翰
    ）
    [345bfg] =＆GT;阵列（
    [0] =＆GT; EDNON
    [1] =＆GT; 345bfg
    [2] =＆GT;伯明翰
    ）
）阵列（
    [345fgfd] =＆GT;阵列（
    [0] =＆GT;阀
    [1] =＆GT; 345fgfd
    [2] =＆GT;伯明翰
    ）
）
 

解决方案

如果我明白你的问题，你想组具有关键相同值的所有元素 0 到同一阵列。你不能做到这一点 array_chunk ，但低于环路产生的分组阵列

  $结果=阵列（）;的foreach（$改编为$ K =＆GT; $ V）{
    $结果[$ V [0] [$ K] = $ V;
}的print_r（$结果）;
 

Is it possible to array_chunk based on a value within the array?

Array

Array (
[4f5hfgb] => Array (
[0] => ACME
[1] => 4f5hfgb
[2] => Aberdeen
)
[sdf4ws] => Array (
[0] => ACME
[1] => sdf4ws
[2] => Birmingham 
)
[dfgdfg54] => Array (
[0] => EDNON
[1] => dfgdfg54
[2] => Birmingham 
)
[345bfg] => Array (
[0] => EDNON
[1] => 345bfg
[2] => Birmingham 
)
[345fgfd] => Array (
[0] => VALVE
[1] => 345fgfd
[2] => Birmingham 
)
)

Is it possible to chunk those with the same value in [0]?

Desired output

Array (
    [4f5hfgb] => Array (
    [0] => ACME
    [1] => 4f5hfgb
    [2] => Aberdeen
    )
    [sdf4ws] => Array (
    [0] => ACME
    [1] => sdf4ws
    [2] => Birmingham 
    )
)

Array (
    [dfgdfg54] => Array (
    [0] => EDNON
    [1] => dfgdfg54
    [2] => Birmingham 
    )
    [345bfg] => Array (
    [0] => EDNON
    [1] => 345bfg
    [2] => Birmingham 
    )
)

Array (
    [345fgfd] => Array (
    [0] => VALVE
    [1] => 345fgfd
    [2] => Birmingham 
    )
)

解决方案

If I understand your question, you're trying to group all elements that have the same value for key 0 into the same array. You can't do this with array_chunk but the loop below produces the grouped array

$result = array();

foreach($arr as $k => $v) {
    $result[$v[0]][$k] = $v;
}

print_r($result);
