How to add data to a string through a loop?

Question

PHP

$pre_response='';
for ($i=0; $i <2; $i++) { 
  $pre_response.='<div class="line_items"></div'; 
}
echo $pre_response;

Displays 1 block with class line_items. Why? Or I misunderstood something?

Answer 1

Because your closing tag is not closed
