php - Strange linebreak characters showing up in my view -

-

i using codeigniter generate html table insertion template view. how insert linebreaks in generated html code , experimentation, have been able change code to: 

$string='<table id="mydatatable" class="table table-bordered table-striped" style="clear: both">\n <tbody>\n';      foreach ($array $key => $value) {      $string=$string."\t\n<tr><td>$key</td>";       $element='<td><a href="#" id="'.$key.'" data-type="text" data-pk="'.$rowid.'" data-url="/post" data-title="'.$key.'">'.$value.'</a>'.'</td></tr>\n';     $string=$string.$element;     } $string=$string.'</tbody>\n</table>';

i inject produced html string ci view looks like:

<!doctype html> <html lang="en"> <head>    <base href="<?=base_url();?>">     <meta charset="utf-8">     <meta name="author" content="vitaliy potapov">     <meta http-equiv="cache-control" content="max-age=0" />     <meta http-equiv="cache-control" content="no-cache" />    <link href="css/bootstrap.css" rel="stylesheet">    <link href="//cdnjs.cloudflare.com/ajax/libs/x-editable/1.4.5/bootstrap-editable/css/bootstrap-editable.css" rel="stylesheet"/>   </head>  <body>      <?=$html_string;?>       <script src='js/jquery.js'></script>   <script src="js/bootstrap.js"></script>   <script src="//cdnjs.cloudflare.com/ajax/libs/x-editable/1.4.5/bootstrap-editable/js/bootstrap-editable.min.js"></script>  <script language="javascript" type="text/javascript">    $(document).ready(function() { $('#mydatatable').editable(); $.fn.editable.defaults.mode = 'inline'; });  </script>   </body>  </html>

i getting expected table, nbut reason see bunch of generated new line charachters before table when @ generated html.

     \n \n   \n   \n   \n   \n   \n   \n   \n   \n   \n   \n   \n   \n   \n\n

why happening , how can fix this?

escaped characters not interpolated when using single quotes. fix either remove \n string or change code this:

<?php $string='<table id="mydatatable" class="table table-bordered table-striped" style="clear: both">'."\n".' <tbody>'."\n";  foreach ($array $key => $value) {      $string=$string."\t\n<tr><td>$key</td>";       $element='<td><a href="#" id="'.$key.'" data-type="text" data-pk="'.$rowid.'" data-url="/post" data-title="'.$key.'">'.$value.'</a>'.'</td></tr>'."\n";     $string=$string.$element; } $string=$string."</tbody>\n</table>";
