Whenever you want to use, variables inside a string, use " instead of ' to initialize the string.

<?PHP
    $num = "3";
    echo "<input id='loadmore' type='button' value='$num' style=' margin-top: 20px;' />     
   <input id='pages' type='hidden' value='$num' />";
?>

this will work

Demo : https://eval.in/87528

Try this:

<?php

$num = "3";
    echo "<input id='loadmore' type='button' value='{$num}' style=' margin-top: 20px; ' > <input id='pages' type='hidden' value='{$num}'>";
?>

Output:

<input id='loadmore' type='button' value='3' style=' margin-top: 20px; ' > <input id='pages' type='hidden' value='3'>

Keep it simple, use . (dot) to concate variable,

echo '<input id="loadmore" type="button" value="'. $num .'" style=" margin-top: 20px; " > <input id="pages" type="hidden" value="'. $num .'">';

Also have a look at heredoc,

echo <<<EOT
<input id="loadmore" type="button" value="$num" style=" margin-top: 20px; " > <input id="pages" type="hidden" value="$num">
EOT;

DEMO.
