在 PHP 中使用正则表达式替换 json 字符串

Question

如何替换/删除此 JSON 中的某些字符串？我认为可以使用 str_replace 方法或 preg_replace 解决此问题 但我不知道如何添加正则表达式

请帮帮我。

这是我的json

Array
(
    [data] => Array
        (
            [0] => Array
                (
                    [DESC] => bla bal bal
                    [SOLD] => 0
                    [contact_no] => 1234
                    [title] =>  Hiiiii
                    [price] => 10900
                    [big_image] => Array
                        (
                            [0] => http://example.com/images/user_adv/14.jpg
                            [1] => http://example.com/images/user_adv/15.jpg
                        )

                    [small_image] => Array
                        (
                            [0] => http://example.com/images/user_adv/small/14.jpg
                            [1] => http://example.com/images/user_adv/small/15.jpg
                        )

                [tpe] => user
            )

            [1] => Array
                (
                    [DESC] => fo fo fof ofof
                    [SOLD] => 0
                    [contact_no] => 234522
                    [title] => Hellooooo sddf
                    [price] => 0
                    [big_image] => Array
                        (
                            [0] => http://example.com/images/user_adv/154.jpg
                            [1] => http://example.com/images/user_adv/144.jpg
                            [2] => http://example.com/images/user_adv/147.jpg
                        )

                     [small_image] => Array
                        (
                            [0] => http://example.com/images/user_adv/small/154.jpg
                            [1] => http://example.com/images/user_adv/small/144.jpg
                            [2] => http://example.com/images/user_adv/small/147.jpg
                        )

                    [tpe] => user
                )

        )

    [pis] => 3
    [totals] => 23
    [curpage] => 1
    [total_ads] => 71
)

我会使用这个函数将 json 导出到 csv

function array_flatten ($nonFlat) {
    $flat = array();
    foreach (new RecursiveIteratorIterator(
            new RecursiveArrayIterator($nonFlat)) as $k=>$v) {
        $flat[$k] = $v;
    }
    return $flat;
}

$fp = fopen("output.csv","w");
foreach ($json['data'] as $fields) {
    fputcsv($fp, array_flatten($fields));
}
fclose($fp);

上面的代码工作正常，但每个图片链接都有一列，所以看起来很糟糕，我需要将每组图片放在一列 我尝试将正则表达式添加到链接图像的一部分，除了第一个图像 url [0] 并将另一个与它合并，我可以将它们放在一个列中...... 所以对于实验，我将它添加到上面的代码中，但似乎什么也没发生

 $flat[$k] = str_replace('[1-7] => http', "http", $v); 

我希望输出类似这样的输出

....
[big_image] => Array
                        (
                            [0] => http://example.com/images/user_adv/154.jpg
                            http://example.com/images/user_adv/144.jpg
                            http://example.com/images/user_adv/147.jpg
                        )

                    [small_image] => Array
                        (
                            [0] => http://example.com/images/user_adv/small/154.jpg
                            http://example.com/images/user_adv/small/144.jpg
                            http://example.com/images/user_adv/small/147.jpg
                        )
.....

编辑这个.csv文件输出看起来像这样

我希望成为那样的人

好的，我已经修复了

foreach (
    new RecursiveArrayIterator($nonFlat) as $k=>$v) {
 $flat[$k] = is_array($v)?implode(" ",$v):$v;

现在我将每组图像放在一个列上

谢谢:)
