数组中的变量不起作用

我在数组中添加了一个带有长句子的变量，并且我有正确的语法来分隔单词。但是，当我尝试显示数组键1,2,3，...时，我得到了错误Undefined offset。

这是我的示例代码：

$quote = '"'; 
$string = $quote.'asds dasddsfaf fdf
ewfejfierjfnsdafjafj sdf dwiofjwejf iosad dsfosdofjeijfmkslad f
dfsijioewjo fsdlfa'.$quote; 
$newstring = implode('", "', preg_split('/[\s]+/', $string)); 
$arrayz = array($newstring); 
echo $arrayz[2];

回声$newstring给了我："asds", "dasddsfaf", "fdf", "ewfejfierjfnsdafjafj", "sdf", "dwiofjwejf", "iosad", "dsfosdofjeijfmkslad", "f", "dfsijioewjo", "fsdlfa"

我认为您正在使事情复杂化。无需在preg_split这里使用。只需使用explode（）即可。试试这个：

$commer = '"'; 
$string = $commer.'asds dasddsfaf fdf
ewfejfierjfnsdafjafj sdf dwiofjwejf iosad dsfosdofjeijfmkslad f
dfsijioewjo fsdlfa'.$commer;

$newstring = explode(' ', $string);

print_r($newstring);

输出：

Array
(
    [0] => "asds
    [1] => dasddsfaf
    [2] => fdf
    [3] => ewfejfierjfnsdafjafj
    [4] => sdf
    [5] => dwiofjwejf
    [6] => iosad
    [7] => dsfosdofjeijfmkslad
    [8] => f
    [9] => dfsijioewjo
    [10] => fsdlfa"
)

根据评论进行编辑。这应该做您想要的：

$commer = '"'; 
$string = 'asds dasddsfaf fdf ewfejfierjfnsdafjafj sdf dwiofjwejf iosad dsfosdofjeijfmkslad f dfsijioewjo fsdlfa'; 

$arrayz = array();
foreach(explode(' ', $string) as $word) {
    $arrayz[] = $commer . $word . $commer;
}

print_r($arrayz);

输出：

Array
(
    [0] => "asds"
    [1] => "dasddsfaf"
    [2] => "fdf"
    [3] => "ewfejfierjfnsdafjafj"
    [4] => "sdf"
    [5] => "dwiofjwejf"
    [6] => "iosad"
    [7] => "dsfosdofjeijfmkslad"
    [8] => "f"
    [9] => "dfsijioewjo"
    [10] => "fsdlfa"
)
