如何使用键和值来爆炸数组多维

标签: php html arrays multidimensional-array

我有这样的字符串:

$string = Leader,Brian; Elder,Nina,Maria; Member,Duke,Rai,Mike

我做了什么:

$explode = ("; ", $string);

然后会显示它,如:

Array ([0] => Leader,Brian [1] => Elder,Nina,Maria [2] => Member,Duke,Rai,Mike)

但我不想那样。我想让它成为带有键和值的数组mutlidimentional,如下所示:

Array ([Leader] => Brian [Elder] => Array ([0] => Nina [1] => Maria) 
       [Member] => Array ([0] => Duke [1] => Rai [2] => Mike))

那么,如何在表格标签html中显示它呢?

Leader  |  Brian
Elder   |  Nina
        |  Maria
Member  |  Duke
        |  Rai
        |  Mike 

感谢您的关注 NB:如果使用

这样的分隔符很困难,可以更改字符串中的分隔符

explode是迈出良好的第一步。

下一步是迭代其结果并再次爆炸。 然后(在同一循环中)使用第二个explode结果的第一个元素作为键,其余部分作为值。

$string = "Leader,Brian; Elder,Nina,Maria; Member,Duke,Rai,Mike";

$exploded = explode("; ", $string);

foreach($exploded as $element) {
    $arr = explode(',', $element);

    $result[array_shift($arr)] = $arr;
}

var_dump($result);

结果:

array(3) {
  ["Leader"]=>
  array(1) {
    [0]=>
    string(5) "Brian"
  }
  ["Elder"]=>
  array(2) {
    [0]=>
    string(4) "Nina"
    [1]=>
    string(5) "Maria"
  }
  ["Member"]=>
  array(3) {
    [0]=>
    string(4) "Duke"
    [1]=>
    string(3) "Rai"
    [2]=>
    string(4) "Mike"
  }
}

我可能会在拆分字符串并再次拆分后走数组:

$list = explode("; ", $string);
array_walk($list, function(&$element) {
    $names = explode(',', $element);
    // Take the first item off the array type
    $type = array_shift($names);
    // Alter the array in-place to create the sub-array
    $element = [$type => $names]
});

你需要两个"爆炸"

$string = 'Leader,Brian; Elder,Nina,Maria; Member,Duke,Rai,Mike';
$explode = explode("; ", $string);
foreach($explode as $row){
    $explode2 = explode(",", $row);
    foreach($explode2 as $i=>$p ){

        echo ( $i > 0 )?"\n\t|":"\n";
        echo $p;
    }
}

答案 3 :(得分:0)

你需要在你的两个分隔符上爆炸两次,例如:

<?php
$string = "Leader,Brian; Elder,Nina,Maria; Member,Duke,Rai,Mike";

$result = array();
$parts = explode(";", $string);

foreach ($parts as $part)
{
    $kv = explode(",", $part);
    $result[array_shift($kv)] = $kv;
}

// result:
echo '<pre>';
print_r($result);
echo '</pre>';
?>

会给你:

Array
(
    [Leader] => Brian
    [Elder] => Nina
    [Member] => Duke
)

这应该这样做:

<?php
$string = 'Leader,Brian; Elder,Nina,Maria; Member,Duke,Rai,Mike';

$explode = array_map(function($v){return explode(',', $v);}, explode(';', $string));

$new_array = [];

foreach($explode as $k=>$v)
{
    $v[0] = trim($v[0]);

    $new_array[$v[0]] = $v;

    unset($new_array[$v[0]][0]);

    $new_array[$v[0]] = array_values($new_array[$v[0]]);
}

print_r($new_array);
