Undefined Index for Valid key from array in PHP -


while parsing csv file(i have used class found on google), ran problem. here example of array made .csv file(print_r):

  array     (         [0] => array             (                 [site] => viralnova                 [impressions] => 104719                 [ctr] => 0.30%                 [clicks] => 311                 [average cpc] => $ 0.400                 [cpm] => $ 1.19                 [conversion rate] => 1.29%                 [actions] => 4                 [cpa] => $ 31.100                 [spent] => $ 124.40             )          [1] => array             (                 [site] => tmz - desktop                 [impressions] => 103276                 [ctr] => 0.29%                 [clicks] => 295                 [average cpc] => $ 0.400                 [cpm] => $ 1.14                 [conversion rate] => 0.68%                 [actions] => 2                 [cpa] => $ 59.000                 [spent] => $ 118.00             ) )

the problem cannot use "site" index. whenever try to, notice:

<b>notice</b>:  undefined index: site in <b>c:\xampp\htdocs\panel\update\assets\php\core\core-ajax.php</b> on line <b>104</b><br />

line 104 being: 

print $data[0]['site'];

also,

print $data[0]['impressions'];

or

print_r($data[0]);

works without problem , correct value/array.

any ideas?

thanks!!

acc. me code running fine. problem occur when in loop in point index missing.

to resolve issue..

use this..

<?php  if($data[0]['site']){     print $data[0]['site']; }  //  if($data[0]['impressions']){    print print $data[0]['impressions']; }  ?>
