将一个维数组转换为二维数组

Question

我有一个数组，其结构基本上是这样：

array('id,"1"', 'name,"abcd"', 'age,"30"')

我想将其转换为二维数组，每个元素作为键 ->值：

array(array(id,1),array(name,abcd),array(age,30))

任何建议将不胜感激！

我尝试了此代码：

foreach ($datatest as $lines => $value){
    $tok = explode(',',$value); 
    $arrayoutput[$tok[0]][$tok[1]] = $value;
}

但是它不起作用。

Answer 1

假设您想根据您的问题删除所有引号：

$oldArray = array('id,"1"', 'name,"abcd"', 'age,"30"')
$newArray = array();
foreach ($oldArray as $value) {
  $value = str_replace(array('"',"'"), '', $value);
  $parts = explode(',', $value);
  $newArray[] = $parts;
}

Answer 2

您可以做这样的事情：

$a = array('id,"1"', 'name,"abcd"', 'age,"30"');
$b = array();
foreach($a as $first_array)
{
    $temp = explode("," $first_array);
    $b[$temp[0]] = $b[$temp[1]];
}

Answer 3

$AR = array('id,"1"', 'name,"abcd"', 'age,"30"');
$val = array();
foreach ($AR as $aa){
  $val[] = array($aa);
}
print_r($val);

输出：

Array ( [0] => Array ( [0] => id,"1" ) [1] => Array ( [0] => name,"abcd" ) [2] => Array ( [0] => age,"30" ) )

Answer 4

带有 array_map函数：

$arr = ['id,"1"', 'name,"abcd"', 'age,"30"'];
$result = array_map(function($v){
    list($k,$v) = explode(',', $v);
    return [$k => $v];
}, $arr);
print_r($result);

输出：

Array
(
    [0] => Array
        (
            [id] => "1"
        )
    [1] => Array
        (
            [name] => "abcd"
        )
    [2] => Array
        (
            [age] => "30"
        )
)
