How can the issue of not getting text data into the text field be resolved in PHP?

Issue: The problem of not getting text data into a text field in PHP can be resolved by ensuring that the form method is set to "POST" and that the name attribute of the input field matches the key used to access the data in the $_POST superglobal array. 

<form method="POST">
  <input type="text" name="text_field">
  <button type="submit">Submit</button>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $text_data = $_POST["text_field"];
  echo "Text data entered: " . $text_data;
}
?>
