How to Fix \'Array to String Conversion\' Errors in PHP Database Queries?

Array to String Conversion Issue in PHP

When attempting to display a value from a database using SELECT, you may encounter the error message "Notice: Array to string conversion in (pathname)." This error typically arises when you try to treat an array as a string or a variable that can be effortlessly converted to a string.

To resolve this issue, examine the code segment that retrieves the data from the database:

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

The @$money variable is an array that contains the retrieved data from the database. When you try to concatenate it with a string, as seen in the line below, the PHP interpreter attempts to convert the array to a string:

echo '<p>

To correct this, you need to specify the key within the array that corresponds to the desired data. In this case, the field name is "money," so you should modify the code to:

echo '<p>

By making this change, you are explicitly indicating that you want to access the "money" element of the array, which contains the actual numerical value. This will prevent the array-to-string conversion error and allow you to correctly display the money value.
