Building a string in a for loop

[Kano]

HI there,

 

When adding strings together I have read that the code is:

 

$msg = " blarb";

$msg .= "blarb"; // with a dot

 

OK, so can someone help me in understanding how this can be achieved with a for loop. So far I have:

 

for($cnt=0;$cnt<$max;$cnt++) { $invoice_msg = "$orderline[$cnt]\n\n"; }

 

obviously, the loop keeps replacing the contents of the variable,

 

can someone help me please,

 

many thanks.

<?php
  for ($cnt=0;$cnt<$max;$cnt++) {
    $invoice_msg .= $orderline[$cnt]."\n\n";
  }
?>

 

Even easier.

 

<?php
  foreach ($orderline as $val) {
    $invoice_msg .= $val."\n\n";
  }
?>

 

Then... easier again.

 

<?php
  $invoive_msg = implode("\n\n",$orderline);
?>

Thanks, thorpe. A dot at each end, I put one before the assignment operator but never considered after the variable, cool.

That second period is just used to concatinate the "\n\n" onto the end.
