In what situations might an object be mistakenly used as an array in PHP, leading to errors like "Cannot use object of type mysqli as array"?

When an object is mistakenly used as an array in PHP, it can lead to errors like "Cannot use object of type mysqli as array" because objects and arrays are distinct data types in PHP. To solve this issue, make sure to access object properties using the arrow (->) notation instead of array syntax. This will allow you to properly interact with the object's properties and methods without triggering errors related to array usage. 

// Incorrect usage causing error
$mysqli = new mysqli("localhost", "username", "password", "database");
echo $mysqli['host']; // This will throw an error

// Correct usage
echo $mysqli->host; // Accessing object property using arrow notation
