What are common reasons for the error "Fatal error: Cannot increment/decrement overloaded objects nor string offsets" in PHP scripts?

The error "Fatal error: Cannot increment/decrement overloaded objects nor string offsets" occurs when attempting to use the increment (++) or decrement (--) operators on objects or string offsets that do not support these operations. To solve this issue, you can explicitly cast the object or string offset to an integer before performing the increment or decrement operation. 

// Example of casting object to integer before incrementing
$object = new stdClass();
$object->value = 5;
$object->value = (int)$object->value + 1;

// Example of casting string offset to integer before incrementing
$string = "5";
$string = (int)$string + 1;
