I am having a problem trying to explode an array, connection to database works and tested, the commented print line works, but the explode doesn't, every time i explode the item it
prints ArrayArrayAray. I have been stuck on this for so long, looked everywhere, followed examples but to no avail. If anyone could help it will be much appreciated.

          $result_ = mysql_query("SELECT * FROM " .PRODUCT_INSTRUCTIONS. " order by group_code") or  
                        die($errorhandler->add("ERROR", __FILE__ . "=>" . __CLASS__ . "=>" . __FUNCTION__ . "=>" . __LINE__, "Failed getting items." . mysql_error()));

                         while($rows_=  mysql_fetch_array($result_)){
                                  $instruction = $rows_['instructions'];
                                 // print "<tr><td>".$rows_['group_code']."</td></tr>"." <tr><th>".$instruction."</th></tr>";
                                  $inst = explode("|", $instruction);

                                  for($i = 0; $i < count($inst); $i++){
                                      echo $inst;
                                  }

                              }

                        ?>

You are echo $inst;ing each time. In other words, you are outputting the array each time, not the array's contents. –  Niet the Dark Absol Jul 3 at 9:34

echo $inst[$i]...!? –  deceze Jul 3 at 9:35
    
Explode returns an array of strings, I think you should echo $inst[$i]; –  MiPnamic Jul 3 at 9:36
    
Thanks for your contribution –  Martin Snitram Jul 3 at 11:48

Add the index to the echo command.

for($i = 0; $i < count($inst); $i++){
    echo $inst[$i];
}

To print off arrays, use var_dump() instead.

$instruction = $rows('instructions');
                             // print "<tr><td>".$rows_['group_code']."</td></tr>"." <tr><th>".$instruction."</th></tr>";
                              $inst = explode("|", $instruction);

                              for($i = 0; $i < count($inst); $i++){
                                  echo $inst[$i];
                              }

replace 

echo $inst;

with 

print_r($inst);

This isn't what he asked in the code, he wants the loop to echo each element, not dump the array 3 times. –  James Hunt Jul 3 at 9:46
    
Yes you right, your answer is correct, need to write echo $inst[$i]. –  Nebojsa Susic Jul 3 at 9:52

for($i = 0; $i < count($inst); $i++)
{
    //If $inst is an array it will print the array else it print as string
    if(is_array($inst))
        print_r($inst);
    else
        echo $inst;
}

When entering code in an answer, it's best to explain what it does. –  DavidG Jul 3 at 10:19
