How to Fix the \"Array to String Conversion\" Error in PHP SELECT Queries?

Array to String Conversion Error in PHP SELECT Query

In PHP, when using a SELECT query to retrieve data from a database, it's common to retrieve results as an array. However, attempting to display an array directly in an echo statement can result in an "Array to string conversion" error. Let's explore how to resolve this issue effectively.

Understanding the Error

The error message "Array to string conversion in (pathname) on line 36" indicates that the code is trying to convert an array into a string, which is not a valid operation. In your case, the line causing the error is:

<code class="php">echo '<p id= "status">'.$_SESSION['username'].'<br>
Money: '.$money.'.
</p>';</code>

Here, $money is an array containing the money value for the current user. However, the code attempts to print $money directly, which would result in a string conversion error.

Resolving the Issue

To resolve this issue, you need to access the correct element within the $money array, which contains the actual money value. You can do this using the following syntax:

<code class="php">$money['money']</code>

So, the modified code would look like:

<code class="php">echo '<p id= "status">'.$_SESSION['username'].'<br>
Money: '.$money['money'].'.
</p>';</code>

Conclusion

By accessing the specific element within the array, you can properly display the money value as a string without encountering the "Array to string conversion" error. This ensures that the data retrieved from the SELECT query is correctly displayed to the user.
