Answer 1

You have to submit your form through POST or GET. My example will use POST. You also must assign a name to the elements you're posting (such as URL). This is untested, so it may have some errors. But it will give you an idea.

<?php 
if(isset($_POST['submit'])){
    $url = $_POST['url'];
    $getText = file_get_contents("$url", true);
    $Contact = substr_count($getText ,"CONTACTID");
    print_r($Contact);
}
?>  
<form method="POST" action="?">
    <div class="form-group">
        <label for="inputsm">Put URL</label>
        <input name="url" class="form-control input-sm" id="inputsm" type="text">
        <br>
        <input name="submit" type="submit" class="btn btn-info" value="Count Contact">
    </div>
</form>
