I want to display that data in tabular form using table tag and also want to insert that data into a MySQL database.
But I dont understand the array format of data.
My code:
$result = file_get_contents($base);
$obj = json_decode($result);
echo"<table>";
foreach($obj as $item) {
echo"
<tr>
<td>$item['Offer.name']</td>
<td>$item['Browser.display_name']</td>
<td>$item['Stat.payout']</td>
<td>$item['Stat.sale_amount']</td>
<td>$item['Stat.datetime']</td>
<td>$item['Stat.ip']</td>
</tr>
";
}
echo"</table>";
This code gives me a blank output.
i used following code and got output but some errors are still there.
$result = file_get_contents($base);
$obj = json_decode($result, true);
echo"<table border=1>";
$i = 0;
foreach($obj['response'] as $item) {
for($i=0;$i<=10;$i++)
{
echo"
<tr>
<td>{$item['data'][$i]['Offer']['name']}</td>
<td>{$item['data'][$i]['Stat']['payout']}</td>
<td>{$item['data'][$i]['Stat']['sale_amount']}</td>
<td>{$item['data'][$i]['Stat']['status']}</td>
<td>{$item['data'][$i]['Stat']['datetime']}</td>
<td>{$item['data'][$i]['Stat']['ip']}</td>
</tr>
";
}
}
echo"</table>";
my output:
why upper rows are displaying blank values when there is no blank data is present?
and what are those errors?

Answer 1

You're using the wrong syntax. It's difficult to see exactly the results you're expecting, the values of the objects being returned look like they are objects of the original json themselves and without any useful data. However, to clarify for you:
You're returning the json_decode() results as an object and trying to access it as an array.
To return an associative array you need to add the 'assoc' parameter to the function, to read:
json_decode($result, true)
and you were trying to eco out the value directly from the associative array, you need to access it via the key, which will give you the value to read:
$result = file_get_contents($base);
$obj = json_decode($result, true);
echo"<table>";
foreach($obj['request'] as $item) {
echo"
<tr>
<td>{$item['fields'][0]}</td>
<td>{$item['fields'][1]}</td>
<td>{$item['fields'][2]}</td>
<td>{$item['fields'][3]}</td>
<td>{$item['fields'][4]}</td>
<td>{$item['fields'][5]}</td>
</tr>
";
}
echo"</table>";
Also, I've added the curly brackets inside the string to escape the variable expressions.

Answer 2

Since you're getting objects in your response, first try json_decode($result->request) and generally don't use [ ] as you normally would as if your result was array
EDIT: Try outputting the response like this:
echo '<pre>';
print_r($your-variable-here);
echo '</pre>';
Then let me know of the output
