How to Fix the

Troubleshooting "Array to String Conversion" Error in PHP

When attempting to retrieve and display data from a database using PHP's SELECT statement, it's common to encounter the error "Notice: Array to string conversion in..." This often arises when attempting to treat an array as a string.

In the provided code snippet:

  {
  $loggedin = 1;

  $get = @mysql_query("SELECT money FROM players WHERE username = 
 '$_SESSION[username]'");
  $money = @mysql_fetch_assoc($get);

  echo '<p>
Copy after login

The issue lies in the line where the echo statement attempts to concatenate the value of $money to a string. $money is an array, and treating it as a string results in the error.

To resolve this, you should access the array element containing the actual value using:

  echo '<p>
Copy after login

This will retrieve the string value from the "money" column within the $money array and concatenate it to the string.
