我想在屏幕上通过“ for ... in ...”循环显示以下值，但是在解码* .json文件和实现时遇到麻烦。
// Example of *.json file
[{ "ano": "2019","nomeCurso": "ABI - CIÊNCIAS BIOLÓGICAS","idCurso": "01ABI","grupo": "PISM Grupo A","campus": "JUIZ DE FORA","turno": "DIURNO","idGrupo": 75} }]
我有一个index.php：
<?php
// Putting the 'autoload' file of 'vendor' directory to use Twig
require 'vendor/autoload.php';
// Declaring directory 'views' (used to show using Twig)
$loader = new Twig_Loader_Filesystem('views');
// Loading 'views' directory
$twig = new Twig_Environment($loader);
// Create a filter to use in the code
$md5Filter = new Twig_SimpleFilter('md5',function ($string) {
return md5($string);
});
// Add filter
$twig->addFilter($md5Filter);
// Decode the *.json file
$classificacoes = file_get_contents("PISM.json");
$classificacao = json_decode($classificacoes,true);
$twig->render('index.html.twig',array($classificacoes));
?>
...和index.html：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="description" content="Twig Table Template">
<meta name="author" content="fabricioguidine">
<meta name="keywords" content="twig table template">
<title>Twig Table Template</title>
</head>
<body></body>
<!-- for each value in "*.json" add a table with especified values -->
{% for classicacao in classificacoes %}
{{ classificacao.ano }}
{{ classificacao.idCurso }}
{{ classificacao.grupo }}
{{ classificacao.campus }}
{{ classificacao.turno }}
{{ classificacao.idGrupo }}
{% endfor %}
</body>
<footer></footer>
</html>
请注意，我是该框架中的新手，可能是愚蠢的实现错误。
您能帮我吗？
