Question

是否有一种使用php删除元素的简单方法像方括号[]和逗号，

这是我的示例代码：

while($row = $result->fetch_assoc())
{   
    //$emparray['content'][] = $row;

    $str = "<div class='row games-list'><a href='http://lolphnews.gxx.garena.com/pc_client_news.php?id=".$row['contentid']."' target='_blank'><div class='col-md-12'><div class='games-list-img' style='background-image: url('".$row['thumbnail']."');'></div><div class='game-list-right'><div class='games-list-title'> <h5 class=''>".$row['contentname']."</h5><span class='uploadedTime'>".timeElapsedSinceNow($row['publishdate'])."</span></div><p class=''>".$row['desc_breif']."</p></div></div></a></div>";

    $emparray['content'][] = $str;
    $emparray['type'] = 'html';

}

//write to json file
$fp = fopen('rsspb.json', 'w');
//have a backslashes remover
fwrite($fp, json_encode($string, JSON_UNESCAPED_SLASHES));
fclose($fp);

和输出是这样的：

Answer 1

我无法理解代码的字符串类型（？），但如果您有数组，则可以implode reference {{3}}的值：

$arr = [
    "content" => ["1", "2", "3"],
    "type" => "html"
];

foreach($arr as &$item) {
    if (is_array($item)) {
        $item = implode("", $item);
    }
}

var_dump($arr);

Answer 2

你在JSON字符串中得到方括号的原因是因为你告诉PHP将数据保存在多维数组中。

换句话说，这一行：

$emparray['content'][] = $str;

与此相同：

$emparray['content'] = array ($str);

这会在content索引中创建一个数组，并使用$str字符串的内容填充它。使其成为一个多维（2）维数组。而不只是用字符串本身填充索引删除额外的方括号，您应该发现您的代码正常工作。

请var_dump ($emparray)自己查看。

编辑：根据您的评论，您似乎还想向内容添加更多数据。这是您必须做出选择的地方：您是否希望将所有内容作为一个字符串，作为整页HTML;或者如果你想要一个字符串数组，对于页面的不同部分。如果它是前者，那么您可以使用字符串连接来添加到索引中的数据。对于后者，那么你需要使用一个数组，并在客户端处理它。
