注意:尝试访问第300行/opt/lampp/htdocs/about/include/whois.php中int类型值的数组偏移量

Question

我试图编写一个PHP代码，用"\n"将所有的行都炸开，并在其中添加一个<hr>标记。这就是代码的工作方式：

1. 它是一个简单的代码，可以从一个无名服务器请求数据，并将查询与其域扩展相匹配。例如，对于www.google.com，它将接受.com部件，并尝试将其与不同的扩展匹配。此外，它也搜索其他数据。
2. 现在，我想添加一些<hr>标签，以分离，并使其适合我的网站。

这是我查询facebook.com时的结果

现在我想用一些PHP代码来美化它。我想把这些数据分成几个小部分。

我注意到，当您更改域名时，行数不会改变。所以我试着把前十行分开。接下来的4行，等等。并添加

中间的标签。

我的程序收集的数据，存储在一个$result变量中。这是我的密码

    $detailedProperties = [];
    $finalArray = [];
    $words = explode("\n", $result);
    array_push($detailedProperties, $words);
    $lengthOfWords = count($detailedProperties);
    for ($i = 0; $i < $lengthOfWords; $i++) {
        if((string)$i[0]) {
            
            $value = '<div class="container">'.
                    '<hr>'.     
                '</div>';
                array_push($finalArray, $value) ;
        }
        $value = "$i[0]"."\n"."$i[1]"."\n"."$i[2]"."\n"."$i[3]"."\n"."$i[4]"."\n"."$i[5]"."\n"."$i[6]"."\n"."$i[7]"."\n"."$i[8]"."\n"."$i[9]"."\n";
        array_push($finalArray, $value);
        if($i[10]) {
            
            $value = '<div class="container">'.
                    '<hr>'.     
                '</div>';
                array_push($finalArray, $value) ;
        }
        if($i[16]) {
            
            $value = '<div class="container">'.
                    '<hr>'.     
                '</div>';
                array_push($finalArray, $value) ;
        }
        if($i[20]) {
            
            $value = '<div class="container">'.
                    '<hr>'.     
                '</div>';
                array_push($finalArray, $value) ;
        }
    }
    
    return 
        "<div class='row cta-content'>".
            "<div class='offerdescription'>".
                "<div class='container' style='font-size:20px'>".
                    // $detailedProperties;
                    
                    "<span class='search-results'><strong>$domain</strong> Domain lookup results from <strong>$whoisserver</strong> Server\n\n</span>" . $finalArray.
                "</div>".
            "</div>".
        "</div>";

现在，错误日志：

这些程序打印的是Array，而不是我上面附加的数据。( facebook数据)

你能告诉我我做错了什么吗？

Answer 1

这可能会被缩短和/或改进，但它比您拥有的更好：

$lines = explode("\n", $result);
$value = "\n<div class='container'><hr></div>\n";
$output[] = implode("\n", array_slice($lines, 0, 11));  //get first 11
$output[] = implode("\n", array_slice($lines, 11, 6));  //get next 6
$output[] = implode("\n", array_slice($lines, 17));     //get remaining
$finalArray = implode($value, $output);

return 
    "<div class='row cta-content'>
        <div class='offerdescription'>
            <div class='container' style='font-size:20px'>
                <span class='search-results'><strong>$domain</strong> Domain lookup results from <strong>$whoisserver</strong> Server\n\n</span>
                $finalArray
            </div>
        </div>
     </div>";

Answer 2

$i[10]是语法错误，$m[n]表示检索具有关联键n的$m数组值。

应该是这样的：

if($i <= 10) {
    //...
} elseif($i > 10 && $i <=16) {
    //...
} else {
    //...
}
