类似于将键、Org、Abuse.Handle、和% Org Tech.Ref更改为OrgTechRef。

Answer 1

您可以在替换()、键() 地图()和联合()的帮助下尝试这样的方法。

步骤：

1.首先使用array_keys()从数组中获取密钥。

然后，2.通过替换不需要的字符(如%、. - )和使用array_map()和str_replace()来修改键。

3.最终将修改后的键与现有值相结合，以生成结果数组$result。

<?php
$array = [
          "nic.hdl" => "RD4299-RIPE",
          "abuse-mailbox" => "domain@fb.com",
          "% This query was served by the RIPE" => ""
         ];

// replacing unwanted characters from every key
function replace_characters($n)
{
    return str_replace(array('-', ' ', '.','%'), '', $n);;
}

$keys = array_keys($array);
$proper_keys = array_map("replace_characters", $keys);
$result = array_combine($proper_keys,$array); // combine modified key & value
print '<pre>';
print_r($result);
print '</pre>';
?>
