for($j=0;$j<count($ink_name);$j++)
{
         $sql[] = "insert into stock_color (I_Code,I_Qty,I_Name) values ('$ink[$j]','$Qty[$j]','$ink_name[$j]')"

Answer 1

please try this code

<?php
 $ink=array('M1','M2','M1','M3','M4');
 $Qty=array(50,50,25,70,15);
 $ink_name=array('PYC','PYC','P285C','P285C','P285C');

 for($j=0;$j<count($ink_name);$j++)
  {
     //$sql .= "insert into stock_color (I_Code,I_Qty,I_Name) values ('$ink[$j]','$Qty[$j]','$ink_name[$j]')";
    if($j==0){
        $sql .= " ('$ink[$j]','$Qty[$j]','$ink_name[$j]')";
    } else {
        $sql .= ", ('$ink[$j]','$Qty[$j]','$ink_name[$j]')";
    }

   }
   echo $final_query = "insert into stock_color (I_Code,I_Qty,I_Name) values " .$sql;
