Help!!!

Ok I have 3 arrays in a table after an explode which contains these values:

$line[1] = Dauksa
$line[2] = Emmanuel
$line[3] = EIMP
$line[4] = Department of Test
$line[5] = Montreal
$line[6] = Canada

$line[1] = Howlett
$line[2] = Liam
$line[3] = EIMP
$line[4] = Department of Test
$line[5] = Montreal
$line[6] = Canada

$line[1] = Flint
$line[2] = Keith
$line[3] = EIMP
$line[4] = Department of Test
$line[5] = Montreal
$line[6] = Canada

I would like to store in a variable called Co_Authors_Last_Name the values taken from $line[1] for each array.

Basically, Co_Authors_Last_Name should have stored values of Dauksa Howlett and Flint

How do I do this?

Here is the code I started on:

foreach ($_POST['AbstractAuthors'] as $row => $value)
$no_co_authors++;

if ($no_co_authors > 0) // If number of co-authors > 0
{

// The code below explodes a complicated string into 6 values indicated above.

foreach ($_POST['AbstractAuthors'] as $row => $value)
{
$pres_author = substr($value, -28);
$pres_author_true = strcmp("isPresentingAuthor{{{true}}}", $pres_author);

  if ($pres_author_true != 0)
     {
        $line = explode("{{{", $value);

        for($x = 0; $x < count($line);++$x) 
          { 
            $line[$x] = substr($line[$x],0,strpos($line[$x],"}}}")); 
          }

     }

}

Looks like all you need to do is set a string for it, and keep adding in your loop.

$authors = "";
for($x=0;$x<count($line);$x++) { 
    $authors .= $line[0]." "; 
}

I am not sure where I should your for loop in my code...I tried placing after the last for -->for($x = 0; $x < count($line);++$x)
{
$line[$x] = substr($line[$x],0,strpos($line[$x],"}}}"));
}

but got an empty string 🙁
