how to put a validation on html php code

My question is about validation in html. At the moment, if I input 100 or 1000 it will work as intended.

This is my html code:

<tr>
    <th scope="row" colspan = "1"><font size="5">Number of Guests:</th>
    <td colspan = "2"><input type = "text" name = "guest" maxlength = "4" id="guest" 
    pattern="[0-9]{3,4}" title = "Number of guests must be more than 100 people."></td>
</tr>

My problem is that when I try to input 001 or 000 it still works. How can I counter that problem? Do I have to validate in php? Thank you for any comments or suggestions.

Use following code to get you desired value only.

   <input type = "text" name = "guest" maxlength = "4" id="guest" min="100" max="1000" pattern="^[1-9][0-9]*$" title = "Number of guests must be more than 100 people.">

Try this pattern: ^(0?[1-9][0-9]{2}|[1-9][0-9]{3})$

this way you disallow input 0100,001,099,0099
