连接数组在循环PHP

Question

我有这个数组

[0] => Array
        (
            [0] => My name
            [1] => is
            [2] => John
        )

[1] => Array
        (
            [0] => My name is Jane
        )

如何实现这种输出，请参见下文。 如果数组数大于一，我想将它们合并为一个。

[0] => Array
        (
            [0] => My name is John
        )

[1] => Array
        (
            [0] => My name is Jane
        )

这是我的代码，但是没有用

foreach ($myArr as $key => $value) {
    if (count($myArr[$key]) > 1) {
        foreach ($value as $k => $v) {
            $myArr[$key] .= $v; 
        }
    }
}

谢谢

Answer 1

为什么不使用内爆？

$data = [['my name', 'is', 'John'],['my name is Jane']];
$results = [];
foreach ($data AS $id=>$datum)
    if (count($datum) > 1)
        $results[$id] = implode($datum, ' ');
    else
        $results[$id] = $datum[0];

结果：

array(2) {
  [0]=>
  string(15) "my name is John"
  [1]=>
  string(15) "my name is Jane"
}

我想是这样的：

foreach ($myArr as $key => $value) {
    if (count($myArr[$key]) > 1) {
        $myArr[$key][0] = '';  
        foreach ($value as $k => $v) {
            $myArr[$key][0] .= $v; 
        }
        array_splice($myArr[$key], 1, count($myArr[$key])-1);
    }
}

我想是这样的：

$ary[0] = Array("My name","is","John");
$ary[1] = Array( "My name is Jane" );
$i=0;       
foreach ($ary as $ar_item)  {
    $merged="";
foreach  ($ar_item as $ar_subitem)  
{
    $merged=$merged.$ar_subitem." ";
}
$ary[$i]=$merged;
$i++;
}
var_dump($ary);
