[英]How to display data from json url using php decode?
问题描述
I am not able to display data from this url using php json decode: https://api.mymemory.translated.net/get?q=Hello%20World!&langpair=en|it 
我无法使用php json解码显示来自此URL的数据： https : //api.mymemory.translated.net/get? q = Hello%20World! & langpair = en|it
here is the data provider: https://mymemory.translated.net/doc/spec.php 这是数据提供者： https : //mymemory.translated.net/doc/spec.php
thanks. 谢谢。
What I want is to setup a form to submit words and get translation back from their API. 我想要的是设置一个表单以提交单词并从其API返回翻译。
here is my code sample: 这是我的代码示例：
<?php $json = file_get_contents('https://api.mymemory.translated.net/get?q=Hello%20World!&langpair=en|it'); // parse the JSON $data = json_decode($json); // show the translation echo $data; ?>

My guess is that you might likely want to write some for loops with if statements to display your data as you wish: 我的猜测是，您可能希望使用if语句编写一些for循环，以if需要显示数据：
Test 测试
$json = file_get_contents('https://api.mymemory.translated.net/get?q=Hello%20World!&langpair=en|it');
$data = json_decode($json, true);
if (isset($data["responseData"])) {
foreach ($data["responseData"] as $key => $value) {
// This if is to only display the translatedText value //
if ($key == 'translatedText' && !is_null($value)) {
$html = $value;
} else {
continue;
}
}
} else {
echo "Something is not right!";
}
echo $html;
Output 产量
Ciao Mondo!
<?php
$html = '
<!DOCTYPE html>
<html lang="en">
<head>
<title>read JSON from URL</title>
</head>
<body>
';
$json = file_get_contents('https://api.mymemory.translated.net/get?q=Hello%20World!&langpair=en|it');
$data = json_decode($json, true);
foreach ($data["responseData"] as $key => $value) {
// This if is to only display the translatedText value //
if ($key == 'translatedText' && !is_null($value)) {
$html .= '<p>' . $value . '</p>';
} else {
continue;
}
}
$html .= '
</body>
</html>';
echo $html;
?>
Output 产量
<!DOCTYPE html>
<html lang="en">
<head>
<title>read JSON from URL</title>
</head>
<body>
<p>Ciao Mondo!</p>
</body>

After many researches I got it working this way: 经过大量研究，我发现它是这样工作的：
$json = file_get_contents('https://api.mymemory.translated.net/get?q=Map&langpair=en|it');
$obj = json_decode($json);
echo $obj->responseData->translatedText;
thank you all. 谢谢你们。
