Extracting JSON text file to a table using PHP - php

Question

I have a json file that I want to read with PHP
http://rh.ernestek.cz.cc/webeast/static.txt
I wanted to extract the "id" and the "key"
I wanted to loop through the id and key so that I can produce a table like this:
ID Key
1 9d07d681e0c1e294264724f7726e6f6f29
3 9cd1e3a4a04b5208862c3140046f73b515
...
I tried to extract the first id and key out using the following code but no luck:
<?php
$json = file_get_contents('static.txt');
$json_decoded = json_decode($json);
echo "ID: ".$json_decoded->static->1->id."<br />";
echo "Key: ".$json_decoded->static->1->key."<br />";
?>
Is there anything I an wrong?
Any ideas?
Thanks!

Answer 1

Decode the json as an array (pass true as second parameter), and loop over the array like so
<?php
$json = file_get_contents('static.txt');
$json_decoded = json_decode($json, true);
foreach ($json_decoded['static'] as $item) {
echo 'ID: ', $item['id'], '<br/>';
echo 'Key: ', $item['key'], '<br/>';
}

By using true in json_decode() it will convert all objects to array:
$json = file_get_contents("http://rh.ernestek.cz.cc/webeast/static.txt");
$json_decoded = json_decode($json, true); // return array
$table = array();
foreach($json_decoded["static"] as $array){
$table[$array["id"]] = $array["key"];
}
//creating the table for output
$output = '<table border="1"><tr><td>ID</td><td>Key</td></tr>';
foreach($table as $id => $key){
$output .= "<tr><td>$id</td><td>$key</td></tr>";
}
$output .= '</table>';
echo $output;
