zend-framework

问题 I'm trying to build a simple PDF document signing routine, using PHP, openssl, and the Zend framework (for pdf redering/handling). I've found this, but it simply won't work, Zend is not able to open any pdf's, not even Zend's own test pdf and Zend will not report why, only that it 'cannot'. I'm pretty sure I would be able to create the keys/certs effectively as that is well documented, but is there a solid approach to attaching the generated certificate to the PDF as the above Zend extension

问题 I'm trying to understand this code, and when I arrived at the final line, I didn't get it. :( Can I have your help in order to find out, what does return $this mean ? public function setOptions(array $options) { $methods = get_class_methods($this); foreach ($options as $key => $value) { $method = 'set' . ucfirst($key); if (in_array($method, $methods)) { $this->$method($value); } } //???? - return what ? return $this; } Update: I've removed my comments for better clarification. 回答1: This way

问题 I have a Controller called "TestController" and several actions in it. For each action I receive a get Parameter ("id"). Something like: test/action1/1 test/action1/2 test/action2/1 test/action3/1 ... Since this parameter can easily be modified I want to check the permissions for this id. Do I have to include this check method in each single action or is there another way? I know that I can't receive params in the constructor but a way like this would be nice. My solution at the moment would

Unfortunately, I'm not sure how to go about this. I think sub-forms might be the way forward, but not too

问题 I am talking about doing something like this: LOCK TABLE page WRITE; SELECT * FROM page WHERE col = 'value'; INSERT INTO page(col1, col2) VALUES('val1', val2); UNLOCK TABLES; 回答1: I don't see an actual Zend DB method to lock tables, but maybe just do this: //Lock Table $sql = "LOCK TABLE page WRITE"; $db->fetchRow($sql); //Get your data $sql = "SELECT * FROM page WHERE col='value'"; $result = $db->fetchAll($sql); //Make the insert $data = array( 'col1' => 'val1', 'col2' => 'val2' ); $db-
