在关联数组php的键和值内搜索字符串

Question

我有一个数组看起来像这样一击 =>

$aarray = [
  "table" => "Balance",
  "where" => ["Balance[+]" => "NOMONEY[-]"]
     ];

我如何在其中搜索“[+]”或“[-]”之类的词并用其他内容替换它们？
ps：想在关联数组的键和值中搜索和替换
另一个 ps：我在谷歌或这个论坛中找不到任何我希望的东西

使用您的示例数据，您可以嵌套任意深度，直到 PHP 的递归限制。

$array = [
    "table" => "Balance",
    "where" => ["Balance[+]" => "NOMONEY[-]"],
];

$new = replaceInArray($array, "[-]", "(minus)");
$new = replaceInArray($new, "[+]", "(plus)");
print_r($new);

这是一个简单的递归函数来替换键和值

function replaceInArray($array, $search, $replace, &$newArray = [])
{
    foreach ($array as $key => $value) {
        $key = str_replace($search, $replace, $key);
        if (is_array($value)) {
            $newArray[$key] = replaceInArray($value, $search, $replace);
        } else {
            $newArray[$key] = str_replace($search, $replace, $value);
        }
    }

    return $newArray;
}

将打印出来

Array
(
    [table] => Balance
    [where] => Array
        (
            [Balance(plus)] => NOMONEY(minus)
        )

)
