Can text field values be read without posting in PHP?

Text field values can be read without posting in PHP by using the $_GET superglobal array. By sending the form data using the GET method, the values will be appended to the URL as query parameters which can then be accessed in PHP using $_GET. 

<form method="get">
  <input type="text" name="textfield">
  <input type="submit" value="Submit">
</form>

<?php
if(isset($_GET['textfield'])) {
  $textfield_value = $_GET['textfield'];
  echo "Text field value: " . $textfield_value;
}
?>
