php - Merging arrays in foreach loop -

i performing csv import database , have trouble adding loop inside array being inserted table.

$lines = 0;  $queries = ""; $linearray = array(); $data = array(); if ($csvcontent) $query = "truncate table $databasetable;"; @mysql_query($query); echo "part list ".$databasetable." updated.\n</br>";     foreach(explode($lineseparator,$csvcontent) $value){       $lines++;       $value = trim($value," \t");       $value = str_replace("\r","",$value);       $value = str_replace("'","\'",$value);       $linearray = explode($fieldseparator,$value);       $linemysql = implode("','",$linearray);       $first = array_splice($linearray, 0, 2);    <... here need have function takes values table , creates array looks $b variable....>  $b=array("1","2","3","4","5","6");  foreach($linearray $x){  $b = implode(",", $b); // example               $row = $first;                 $row2 = $first;             $row[] = $x."','$b"; // here stays static no me. need cycle...                 $data[] = implode("','",$row);          } }  $xx=0; foreach ($data $id) { $xx++;   echo $xx;  $query="insert csv_test3 values ('$id', '-', '-' , '-', '-')"; $init=mysql_query($query); 

in essence need figuring out how merge $b array foreach loop goes this:

array(18) {   [0]=>   string(23) "a','z','1','1,2,3,4,5,6"   [1]=>   string(23) "a','z','0','1,2,3,4,5,6"   [2]=>   string(23) "a','z','1','1,2,3,4,5,6"   [3]=>   string(23) "a','z','1','1,2,3,4,5,6"   [4]=>   string(23) "a','z','0','1,2,3,4,5,6"   [5]=>   string(23) "a','z','0','1,2,3,4,5,6"   [6]=>   string(23) "b','y','1','1,2,3,4,5,6"   [7]=>   string(23) "b','y','0','1,2,3,4,5,6"   [8]=>   string(23) "b','y','0','1,2,3,4,5,6"   [9]=>   string(23) "b','y','1','1,2,3,4,5,6"   [10]=>   string(23) "b','y','0','1,2,3,4,5,6"   [11]=>   string(23) "b','y','0','1,2,3,4,5,6"   [12]=>   string(23) "c','x','1','1,2,3,4,5,6"   [13]=>   string(23) "c','x','1','1,2,3,4,5,6"   [14]=>   string(23) "c','x','1','1,2,3,4,5,6"   [15]=>   string(23) "c','x','1','1,2,3,4,5,6"   [16]=>   string(23) "c','x','0','1,2,3,4,5,6"   [17]=>   string(23) "c','x','0','1,2,3,4,5,6" } 

to this:

array(18) {   [0]=>   string(23) "a','z','1','1"   [1]=>   string(23) "a','z','0','2"   [2]=>   string(23) "a','z','1','3"   [3]=>   string(23) "a','z','1','4"   [4]=>   string(23) "a','z','0','5"   [5]=>   string(23) "a','z','0','6"   [6]=>   string(23) "b','y','1','1"   [7]=>   string(23) "b','y','0','2"   [8]=>   string(23) "b','y','0','3"   [9]=>   string(23) "b','y','1','4"   [10]=>   string(23) "b','y','0','5"   [11]=>   string(23) "b','y','0','6"   [12]=>   string(23) "c','x','1','1"   [13]=>   string(23) "c','x','1','2"   [14]=>   string(23) "c','x','1','3"   [15]=>   string(23) "c','x','1','4"   [16]=>   string(23) "c','x','0','5"   [17]=>   string(23) "c','x','0','6" } 

i suppose bunch of iterators:

$linearray = [['a','z',1], ['a','z',0], ['a','b',1], ['a','c',1]];  $a_iter = new arrayiterator($linearray);  $b_iter = new limititerator(new infiniteiterator(new arrayiterator(array("1","2","3","4","5","6"))), 0, count($linearray));  $m_iter = new multipleiterator(multipleiterator::mit_keys_assoc); $m_iter->attachiterator($a_iter, 'a'); $m_iter->attachiterator($b_iter, 'b');  foreach ($m_iter $item) {         print_r(array_merge($item['a'], array($item['b']))); } 

the multipleiterator allows loop on multiple iterators @ same time:

1. a standard arrayiterator feeds $linearray

2. an infiniteiterator continuously loops on array of numbers, limited number of items in $linearray

inside foreach can "pluck" values both iterators.
