undefined offset help

[sasori]

hi, here's my code

        $handle = read_file($txt);
        $var_array_parent = explode("\n", $handle);
        foreach($var_array_parent as $value) {
          $var_array = explode(";", $value);
          $a = array_chunk($var_array, 4);
          }
        foreach($a as $k=>$v)
        {
          $temp = explode(' ',$v[1]);
          unset($a[$k][1]);
          $a[$k][] = $temp[0];
          $a[$k][] = $temp[1].$temp[2];
        }
        $b = print_r($a,true);

        for($i=0;$i<count($a);$i++){
        $data = array(
                      "compcode" => $a[$i][0],
                      "price" => $a[$i][4],
                      "percent" => $a[$i][5],
                      "compname" => $a[$i][2],
                      "volume" => $a[$i][3]);

        $this->db->insert('stocks',$data);

 

when am trying to insert it in the db..it returns

what should i do? please help with the coding logic 

[Adam]

Which are lines 53 and 56? That looks like some messy logic.. What is it you're trying to do?

[Buddski]

Im going to guess that line 53 is $temp = explode(' ',$v[1]); and line 56 is $a[$k][] = $temp[1].$temp[2];

Your obviously referencing array keys that do not exist..

You need to make sure that $v and $temp have the associated keys..

sir this was the response from the codeigniter.

I was trying to extract  some jumbled data from a text file and then

input them in mysql...

btw this is the original function before i even put it on the my model in CI.

it use to work by running it alone

$var_array_parent = explode("\n", $handle);
foreach ($var_array_parent as $value) {
    $var_array = explode(";", $value);
    $a = array_chunk($var_array, 4);
}
foreach($a as $k=>$v) {
    $temp = explode(' ', $v[1]);
    unset($a[$k][1]);
    $a[$k][] = $temp[0];
    $a[$k][] = $temp[1].$temp[2];

}

echo '<pre>'.print_r($a, true).'</pre>';

[Buddski]

It would actually help if you actually told us the lines that are at fault.. it may also help for us to see the text document you are reading in..

sir(s) attached is the data that i was trying to read.

after your first foreach statement can you do a var_dump($a) and show us the results..

[sasori]

    function putData($txt)
    {
        $handle = read_file($txt);
        $var_array_parent = explode("\n", $handle);
        foreach($var_array_parent as $value) {
          $var_array = explode(";", $value);
          $a = array_chunk($var_array, 4);
          }
         echo "<pre>",print_r($a),"</pre>";
        foreach($a as $k=>$v)
        {
          $temp = explode(' ',$v[1]);
          unset($a[$k][1]);
          $a[$k][] = $temp[0];
          $a[$k][] = $temp[1].$temp[2];
        }

 

the result was

 

Array
(
    [0] => Array
        (
            [0] => ABA 
            [1] => 0.97 0.00 %
            [2] => Abacus A 
            [3] => 50,000 
        )

    [1] => Array
        (
            [0] => ABS 
            [1] => 22.00 1.1494 %
            [2] => ABS-CBN 
            [3] => 60,700 
        )

and ofcourse there are these errors at the end of it
