Question

我正在尝试从http标头中获取每个元素。然而，curl返回的数组并不是很好的

<?php
$url = "http://www.wdudes.com/";
$curl = curl_init();
curl_setopt_array( $curl, array(
    CURLOPT_HEADER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_NOBODY => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_URL => $url ) );
    $response = curl_exec($curl);
    curl_close($curl);
    $headers = explode( "\n", $response);
    print_r($headers);
?>

获得的输出是

Array ( 
[0] => HTTP/1.1 200 OK 
[1] => Date: Fri, 29 Apr 2016 10:35:20 GMT 
[2] => Content-Type: text/html; charset=UTF-8 
[3] => Connection: close 
)

我想将数组格式化为：

Array ( 
[0] => HTTP/1.1 200 OK 
[Date] => Fri, 29 Apr 2016 10:35:20 GMT 
[Content-Type] => text/html; charset=UTF-8 
[Connection] => close 
)

Answer 1

你实际上可以这样使用：

<?php
    $headers = array(
      "HTTP/1.1 200 OK ",
      "Date: Fri, 29 Apr 2016 10:35:20 GMT ",
      "Content-Type: text/html; charset=UTF-8 ",
      "Connection: close"
    );
    $better = array();
    foreach ($headers as $key => $value) {
      if ($key == 0)
        $better[] = $value;
      else {
        $current = explode(":", $value, 2);
        $better[trim($current[0])] = trim($current[1]);
      }
    }

输出： Demo

Array
(
    [0] => HTTP/1.1 200 OK 
    [Date] => Fri, 29 Apr 2016 10:35:20 GMT
    [Content-Type] => text/html; charset=UTF-8
    [Connection] => close
)

这是基本逻辑。如果有更好，更高效的方法，欢迎他们。

这种方法类似于Praveen的答案，但要确保处理任何带有额外冒号的答案。

for($i = 0; $i < count($output); $i++){

    //If array item contains ": "
    if(strpos($output[$i], ': ') !== false){

        //New key is text before the colon
        $newKey = substr($output[$i], 0, strpos($output[$i], ': '));

        //New val is text after the colon
        $newVal = substr($output[$i], strpos($output[$i], ': ')+1, strlen($output[$i]));

        //Remove item from existing array
        $output[$i] = "";       

        //Write item to array using new key and value
        $output[$newKey] = $newVal;
    }
}

您可以选择从现有阵列中删除＆＃34;删除项目＆＃34;如果不需要就行。

然后，您可以使用print_r（array_filter（$ output））;

显示结果

结果如下：

Original Array
Array
(
    [0] => HTTP/1.1 200 OK
    [1] => Date: Fri, 29 Apr 2016 10:35:20 GMT
    [2] => Content-Type: text/html; charset=UTF-8
    [3] => Connection: close
)


New Array:
Array
(
    [0] => HTTP/1.1 200 OK
    [1] => 
    [2] => 
    [3] => 
    [Date] =>  Fri, 29 Apr 2016 10:35:20 GMT
    [Content-Type] =>  text/html; charset=UTF-8
    [Connection] =>  close
)


Filtered Array:
Array
(
    [0] => HTTP/1.1 200 OK
    [Date] =>  Fri, 29 Apr 2016 10:35:20 GMT
    [Content-Type] =>  text/html; charset=UTF-8
    [Connection] =>  close
)

Answer 3

试试这段代码：

{$var|replace:'value="AA"':'value="'$string_b'"'}
{$var|replace:'value="AA"':'value="`$string_b`"'}
{$var|replace:'value="AA"':'value=""$string_b""'}

Answer 4

解决方案是：

使用$flag变量跳过第一个元素，即HTTP/1.1 200 OK
使用foreach循环遍历数组，并在每次迭代中使用explode()函数获取新的（键，值）对并使用新键将新值推送到适当的位置在数组中
最后，使用数组的旧键

所以你的代码应该是这样的：

// Suppose $headers is your original array

$flag = true;
foreach($headers as $key => $value){
    if($flag){
        $flag = false;
        continue;
    }
    if(strlen(trim($value))){
        $component = explode(": ", $value);
        $headers[$component[0]] = $component[1];
        unset($headers[$key]);
    }else{
        unset($headers[$key]);
    }
}

// display $headers array
var_dump($headers);

CURL返回的响应数组没有格式良好的PHP
