范例

Example #1 Exception::getLine()示例

<?php
try {
    throw new Exception("Some error message");
} catch(Exception $e) {
    echo "The exception was thrown on line: " . $e->getLine();
}
?>

• Throwable::getLine()

Note that it appears to be the line number the Exception was created that is returned, *not* the line it was thrown from.
