JSON not parsing using PHP

Question

My json is

{"productInfoList":[{"prod":"Some Products","price":"someprice"},{"prod":"Another Product","price":"48"}]}

My php code is

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/file.json');
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$voo = curl_exec($ch);
curl_close($ch);
$yf= json_decode($voo,true); 
for ($i=0; $i < 5; $i++)
{
$fkname = $yf->{'productInfoList'}[$i]->{'prod'};
echo $i;
echo $fkname;
}
?>

Output is 012345. How can I get product names using json? The json file is totally fine I checked it using http://jsonviewer.stack.hu/.

Answer 1

After json_decode, the json is converted to a php array.Try replacing this line:

$fkname = $yf->{'productInfoList'}[$i]->{'prod'};

With this line:

$fkname = $yf['productInfoList'][$i]['prod']; 

Here is a working DEMO

Code Improvement
In your loop, use the array size instead of hard-coding the length:

for ($i=0; $i < sizeOf($yf['productInfoList']); $i++)
{
$fkname = $yf['productInfoList'][$i]['prod'];
 echo $fkname."<BR />";
}

• Luthando Ntsekwa: @IdidntKnewIt sorry i had a typo in my demo, please check it again
• Luthando Ntsekwa: @IdidntKnewIt the browser is removing my i++ in the demo i provide, please edit it before you run it

Answer 2

Like this would work:

$yf= json_decode($voo,true); 
$arr = $yf['productInfoList'];
for ($i=0; $i < sizeof($arr); $i++)
{
$fkname = $arr[$i]['prod'];
echo $i;
echo $fkname;
}

Take in count the sizeof function for iterating over an array.

The output would be:

0Some Products1Another Product

Answer 3

use foreach and its simple

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/file.json');
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$voo = curl_exec($ch);
curl_close($ch);
$yf= json_decode($voo,true); 
$i = 0;
foreach($yf['productInfoList'] as $product)
{ 
 echo $i.' - '.$product['prod'].'<br />';
 $i++;
}
?>
