Question

The following script prints the strings from the array named arr. After an echo from arr I try to insert a line break using \n but I don’t see it. Why is that ?

<?php
$arr = array("ghazal","shayari","silence","hayaat");
echo $arr[0];
echo $arr[1];
foreach($arr as $var) {
  echo $var;
  echo "\n";
}

HTML treats all whitespace characters, in any number, identically.

That is, the following will all render as a single space in the browser:

echo "\n";
echo "\t";
echo "         ";
echo "  \n\n\n  ";

In order to render an actual linkbreak in HTML, you need to insert a <br> element into your document.
