In php, how do I fix an array to string conversion error in my code (specifically this line- echo " - $msg
" ;?

Question

This is my code that is returning a error: Notice: Array to string conversion in /Applications/XAMPP/xamppfiles/htdocs/cim/msgboard/login.php on line 29 (echo " - $msg
" ;)

Array

  <?php
          include('includes/header_login.inc') ;
          if (isset($errors) && !empty($errors)) {
          echo '<p id="err_msg">A problem has occurred:<br>' ;
          foreach($errors as $msg) {
          echo " - $msg<br>" ;
          }
         echo 'please try again or <a href="registration-page.php">Register</a></p>' ;  
  }
  ?>

$msg is an array and echo cannot print arrays directly. That's why you're getting the error message. You have to use var_dump($msg) or print_r($msg) or similar. — bestprogrammerintheworld, Jun 23 '20 at 05:48

First of all you have to print message like $msg['message'] and if you want to add some HTML in your PHP it should be like:

echo "- ".$msg['message']."<br>";

When you $msg in " here ", print will like:

-$msg.

PHP can not understand the variable in the echo so you should close the quotes.
