this is wrong: echo'hello';

this is right: echo('hello'); // best way imho

this is right: echo 'right';

Your code could look like this:

echo ('<input type="text" class="form-control" id="state" name="state" placeholder="Enter States" value="' . $_POST['state'] . '">');

The code above works, but if the user enters special characters it can break the HTML of your site (and mean a security issue). So you should use this:

echo ('<input type="text" class="form-control" id="state" name="state" placeholder="Enter States" value="' . htmlentities($_POST['state']) . '">');

The first one is also syntactically valid, just not pretty. – mario Apr 07 '18 at 13:29
@mario - surprising... but you are right. – ESP32 Apr 07 '18 at 15:33

Replace your code with this code:

echo "<input type='text' class='form-control' id='state' name='state' placeholder='Enter States' value='<?php echo $_POST["state"]; ?>'>";
