You can do it like this, using array_search(), reducing the check to 1 line :/

<?php
if (isset($_POST["Search"]) && !empty($_POST['name']))
{
    if (array_search($_POST['name'], file('testfile.txt')) !== false){
        echo "text exist";
    }
    else{
        echo "text doesn't exist";
    }
}
