php-5.3

问题 Disclaimer : I'm working on a legacy corporate WP site (PHP 5.3.3), and I can't make very many major breaking changes. I am adding pagination to an existing resources page (/resources). I'm fairly new to Wordpress in general, but I do have my page working and displaying the correct number of resources on page load. My question is: when you paginate in Wordpress using: <?php next_posts_link( 'More Resources' , $the_query->max_num_pages ); ?> It creates a link on the page, and when you click it

问题 According to the PHPUnit Documentation on @expectedExceptionMessage , the string must only be a substring of the actual Exception thrown. In one of my validation methods, an array item is pushed for each error that occurs, and the final Exception message is displayed by imploding the array of errors. class MyClass { public function validate($a, $b, $c, $d) { if($a < $b) $errors[] = "a < b."; if($b < $c) $errors[] = "b < c."; if($c < $d) $errors[] = "c < d."; if(count($errors) > 0) throw new

问题 I have a question. I have the folowing condition : You should return an HTTP 500 status code and more details about the error in the message body. Set the HTTP content type response to “application/json”.The error detail must be in JSON format as described below: { "ErrorCode" : 402, "ErrorMessage" : "Item" } I tried like this : if(!Gain::verifyIfUserExistByIdm($aOutput['UserId'])){ header("HTTP/1.0 500 Internal Server Error"); return json_encode(array('ErrorCode'=>407,'ErrorMessage'=>'Error'

问题 Hello I am making this call: $parts = $structure->parts; Now $structure only has parts under special circumstances, so the call returns me null. Thats fine with me, I have a if($parts) {...} later in my code. Unfortunately after the code finished running, I get this message: Notice: Undefined property: stdClass::$parts in ... How can I suppress this message? Thanks! 回答1: The function isset should do exactly what you need. PHP: isset - Manual Example: $parts = (isset($structure->parts) ?

问题 What is the difference between forward_static_call and call_user_func And the same question applies to forward_static_call_array and call_user_func_array 回答1: The difference is just that forward_static_call does not reset the "called class" information if going up the class hierarchy and explicitly naming a class, whereas call_user_func resets the information in those circumstances (but still does not reset it if using parent , static or self ). Example: <?php class A { static function bar()

问题 I am upgrading a codebase from php 5.2 to 5.3. As part of this I am converting our uses of deprecated functions and features. When we use deprecated functions like split and spliti the error handler that we setup by calling set_error_handler() is called and I get a log message. This is great. But, when I use the following two deprecated features: Assigning the return value of new by reference is now deprecated. Call-time pass-by-reference is now deprecated. The error handler is not called so

问题 I have two arrays of the form Array1: [0]=> Array([name] => foo [id] => 12) [1]=> Array([name] => bar [id] => 34) Array2: [0]=>Array([name] => bar [id]=> 34) [1]=>Array([name] => baz [id]=> 56) The arrays come from a database and any two pairs can have the same name but ID's are unique. I am trying to compare the arrays by ID likes so: $one_not_two = array_diff($array1[id], $array2[id]); but that does not return anything. I also tried $one_not_two = array_diff($array1[id], $array2[id]); which

问题 I have a tree of Zone objects: class Zone { protected $parent; public function __construct(Zone $parent) { $this->parent = $parent; } } There are no children nor descendants property in the Zone, because I want to avoid the pain of managing these relationships in the domain model. Instead, a domain service maintains a closure table in the database, to map a zone to all its descendants, at any level. Now, I have a User which can be assigned one or more Zones: class User { protected $zones;
