Question

Below is the code that I am currently using:

  $form = "
  <form action='echo htmlentities($_SERVER["PHP_SELF"]);' method='post'>
  <table>
  <tr>
  <td>Username</td>
  </td><input type='text' name='user' value='$getuser' /></td>
  </tr>
  </table>
  </form>";

  ?>

The above code is giving me this error:

Parse error: syntax error, unexpected '"', expecting T_STRING or T_VARIABLE or T_NUM_STRING in ... on line 27

If I change this: ["PHP_SELF"] to this ['PHP_SELF'], then I recieve this error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in ... on line 27

How can I fix the form action above so that it stops returning with parse errors?

Change:

<form action='echo htmlentities($_SERVER["PHP_SELF"]);' method='post'>

to

<form action='" . htmlentities($_SERVER["PHP_SELF"]) . "' method='post'>

You’re already in PHP and building a string so there’s no need for the echo within the string.
