Exception Handling

phpy provides encapsulation for handling exceptions in Python by introducing the PyError class, allowing PHP code to catch Python exceptions.

Inheritance

PyError is a subclass of the Exception class.

List of Properties

• error: The error object
• type: The error type
• value: The error value
• traceback: The traceback stack of the error

These properties are either PyObject objects or null.

Catching Exceptions

try {
    PyCore::import('not_exists');
} catch (PyError $e) {
    PyCore::print($e->error);
    PyCore::print($e->type);
    PyCore::print($e->value);
    PyCore::print($e->traceback);
}

• The underlying code will automatically set the string value of $e->value as the exception message, which can be accessed using $e->getMessage().
• The PyError does not set an error code $e->code, so please do not use it.
