How can you prevent the error "Fatal error: Cannot use object of type stdClass as array" in PHP?

The error "Fatal error: Cannot use object of type stdClass as array" occurs when you try to access an object property using array syntax. To prevent this error, you should use object syntax to access object properties instead of array syntax. You can do this by using the arrow (->) operator to access object properties. 

// Incorrect way that may cause the error
$obj = new stdClass();
$obj->key = 'value';
echo $obj['key']; // This will cause the error

// Correct way to access object property
echo $obj->key; // This will output 'value'
