php - print array value to txt -

-

i write program have array printed in txt file:

$dataset   = array(); $dataset[] = array('a','b','c','d'); $dataset[] = array('a','d','c'); $dataset[] = array('b','c'); $dataset[] = array('a','e','c'); $arrlength=count($dataset); for($x=0;$x<$arrlength;$x++){         file_put_contents ('filename.txt', implode(',',$dataset[$x])."\n", file_append);    }

the code above produce txt file:

a,b,c,d a,d,c b,c a,e,c

but when try to print array db txt adopting previous code, doesn't give me desired output. here code:

$result=array();         $key='sub';         foreach($this->click_model->getclickstream() $row)         {              $result[$row['id_click']]['sub'][]=  $row['id_kampanye'].$row['code'];             $newresult=array_column($result,$key);             file_put_contents ('datasetarray.txt', print_r($newresult, true));              $arrlength=count($newresult);             for($x=0;$x<$arrlength;$x++){                  file_put_contents ('dataset.txt', implode(',',$newresult[$x])."\n", file_append);               }          }

the code above give me txt file below:

17p3 17p3,16visitor 17p3,16visitor 5visitor 17p3,16visitor 5visitor,18p3 17p3,16visitor 5visitor,18p3,15visitor 17p3,16visitor

and array $newresult is:

array (     [0] => array         (             [0] => 17p3             [1] => 16visitor             [2] => 15visitor             [3] => 17p3             [4] => 5visitor         )      [1] => array         (             [0] => 5visitor             [1] => 18p3             [2] => 15visitor             [3] => 5visitor             [4] => 18p3             [5] => 10visitor         )      [2] => array         (             [0] => 15visitor             [1] => 15visitor             [2] => 15visitor             [3] => 15visitor             [4] => 15visitor             [5] => 15visitor             [6] => 15visitor             [7] => 15visitor             [8] => 15visitor         ) }

my expected output:

17p3,16visitor,15visitor,17p3,5visitor 5visitor,18p3,15visitor,5visitor,18p3,10visitor 15visitor,15visitor,15visitor,15visitor,15visitor,15visitor,15visitor,15visitor,15visitor

please me, don't know what's wrong code.

use loop outside foreach loop, work you..

<?php  $result=array(); $key='sub';  foreach($this->click_model->getclickstream() $row) {     $result[$row['id_click']]['sub'][]=  $row['id_kampanye'].$row['code'];     $newresult=array_column($result,$key);     file_put_contents ('datasetarray.txt', print_r($newresult, true)); }  $arrlength=count($newresult); for($x=0;$x<$arrlength;$x++) {     file_put_contents ('dataset.txt', implode(',',$newresult[$x])."\n", file_append); } ?>
