php - 从 CURL 响应中获取特定行

问题描述

我正在研究 WHMCS API 并在 curl 中获得响应。我必须从第 25 行准确获取值。响应看起来像这样..

  array(1) {
    ["product"]=>
    array(1) {
      [0]=>
      array(41) {
        ["id"]=>
        int(107)  // This is line 25

我必须获取括号内的整数（然后在我的 bash 脚本中将其用作变量）。对于上面的示例，它是 107。

有没有更简单的方法来实现这一点。

这是我的 php 文件包含。

$username = "something";  
$password = "something";  
  
// Set post values

    'username' => $username,

// Call the API  
$ch = curl_init();  
curl_setopt($ch, CURLOPT_URL, $whmcsUrl . 'includes/api.php');  
curl_setopt($ch, CURLOPT_POST, 1);  
curl_setopt($ch, CURLOPT_TIMEOUT, 30);  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);  
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);  
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postfields));  
$response = curl_exec($ch);  
if (curl_error($ch)) {  
    die('Unable to connect: ' . curl_errno($ch) . ' - ' . curl_error($ch));  
}  
curl_close($ch);  
  
// Decode response  
$jsonData = json_decode($response, true);  

// Dump array structure for inspection 
var_dump($jsonData);

解决方案

如果您只需要变量中第 25 行的数字，您可以使用它sed

var=$(sed -n '25s/.*(\([0-9]*\))/\1/p' $file)
