Google货币转换器返回奇怪的字符串

问题描述：

I'm trying to do a curl request to the google currency converter URL. This part works, and I get back the JSON data however the data appears to be in the wrong encoding. If I try to convert encoding or adjust the values in any way it doesn't work and my json_decode returns NULL.

Do I need to specify encoding or is it related to the keys not having quotes around them?

Here's some code to get a result from them:

    $url = "https://www.google.com/ig/calculator?hl=en&q=" . $amount . $from . "=?" . $to;

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    $return = curl_exec($ch);
    curl_close($ch);

    var_dump($return);

The result is usually something around this {lhs: "9Â 808.90 U.S. dollars",rhs: "7Â 986.40287 Euros",error: "",icc: true}

I converted the encoding to ISO-8859-1 and it had proper spaces, but it still won't json_decode properly...

Any suggestions?

我正在尝试对谷歌货币转换器URL进行卷曲请求。这部分工作，我收回JSON数据，但数据似乎是错误的编码。如果我尝试转换编码或以任何方式调整值它不起作用，我的json_decode返回NULL。 p>

我是否需要指定编码，还是与没有引号的键相关？ p>

以下是一些从中获取结果的代码： p>

  $ url =“https://www.google.com/ig  / calculator？hl = en＆amp; q =“。  $金额。  $来自。  “=？”  。  $ to; 
 
 $ ch = curl_init（）; 
 curl_setopt（$ ch，CURLOPT_URL，$ url）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，1）; 
 curl_setopt（$ ch，CURLOPT_USERAGENT，“Mozilla  /4.0（兼容; MSIE 8.0; Windows NT 6.1）“）; 
 curl_setopt（$ ch，CURLOPT_TIMEOUT，60）; 
 $ return = curl_exec（$ ch）; 
 curl_close（$ ch）; 
 
  var_dump（$ return）; 
  code>  pre> 
 
 结果通常是这个 {lhs：“9808.90美元”，rhs：“7,986.40287欧元”  ，错误：“”，icc：true}  code>  p> 
 
 
我将编码转换为ISO-8859-1并且它有适当的空格，但它仍然不能正确地进行json_decode。  ..  p> 
 
 

有任何建议吗？ p>

I never get that weird strings.

test.php

<?php
    $amount = '10$';
    $to = 'EUR';
    $url = "https://www.google.com/ig/calculator?hl=en&q=" . $amount . $from . "=?" . $to;

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    $return = curl_exec($ch);
    curl_close($ch);

    // dump the output
    var_dump($return);

    /*
    string(59) "{lhs: "10 US$",rhs: "8.14199642 Euros",error: "",icc: true}"
    */

    // quote the unquoted data from Google
    $forJSON = str_replace(array('lhs', 'rhs', 'error', 'icc'), array('"lhs"', '"rhs"', '"error"', '"icc"'), $return);

    // decode the JSON string and turn it into an array
    $toArray = json_decode($forJSON, true);

    // dump the array
    print_r($toArray);

    /* 
    Array
    (
        [lhs] => 9 808.90 U.S. dollars
        [rhs] => 7 986.40287 Euros
        [error] => 
        [icc] => 1
    )
    */
?>

things you should try:

make sure you save your file as ANSI - you will get weird values otherwise
if above sollution doesn't work, try remaking the file, there must be an encoding somewhere.
or maybe you copied 9,808.90 from some program that doesn't actually use , and it's another character there
also you should know that Google responds with unquoted data, that is not JSON valid, try to escape like I did and you should be able to decode

You have the values "808.90 U.S. dollars". Just explode() the string and extract the data .

$data = explode('"', $url);
$data = explode(' ', $data['3']);
$var = $data['0'];
return round($var,3);
