I tried to explode some JSON but I got an error, "Undefined offset: 1." I don't know how to fix it. I tried to var_dump the JSON content, it shows the string word I need. However, when I try to explode and foreach it, I get an error. Please help me.

This is the code:

$json = file_get_contents('http://localhost/project/services/grafik');
$encoding = json_encode($json,true);
$pecah = explode(",",$encoding);
// var_dump($pecah);

foreach($pecah as $row => $data)
{
    $p1 = explode(',', $data);
    $p2[$row] = explode(',',$p1[0]);
    $nama=$p2[$row][0];
    $jumlah=$p2[$row][1];
}

This is the JSON content:

"Windows XP Prof ,106, Windows 7 ,43, Windows Vista Business ,13, Windows 7 Prof ,21, B4 ,1, Windws 7 Prof ,1, IPCOP ,1, Windows 2003 server ,4, Windows 2008 server ,1, Windows 2008 R2 ,4, NULL ,9, Windows 8 Prof ,6,operating,1,"

  • i have used decode, but when i used decode, it become very complicated, i received NULL when i tested JSON with var_dump. first time i create this the data still appear on $nama and $jumlah, then there's error offset. but now.. i do not know what im doing, its become more difficult $nama and $jumlah does not appear anymore..just error offset appear.

  • $pecah = json_decode($encoding, true); this way the json will be decoded into an array which will make it less complicated. Commented Aug 24, 2014 at 15:33
  • many thanks any people for feedback, i tried decode the $encoding, but its return NULL value.., Commented Aug 24, 2014 at 15:47
