parent-child

I have an array like that: <?php array( array( 'id' => 1, 'parent_id' => null ), array( 'id' => 2, 'parent_id' => 1 ), array( 'id' => 3, 'parent_id' => null ), array( 'id' => 4, 'parent_id' => 2 ) ) I need to sort it to every child comes after it's immediate parent. So, ID 4 item should come right after ID 2. Thanks. Working solution : PHP has user define sorting function uasort I have used this to sort your array. <?php $data = array( array( 'id' => 1, 'parent_id' => null ), array( 'id' => 2, 'parent_id' => 1 ), array( 'id' => 3, 'parent_id' => null ), array( 'id' => 4, 'parent_id' => 2 ) );

I have three View Controllers (VC1, Parent View Controller and Child View Controller). How do I pass data from the VC1 to the child View controller when the ParentVC is loaded?

But unfortunately, this logic is not working. I've tried to pass the the data from VC1 to the ParentVC then to the

In which way should I access this parent method and parent variable? class Base { public: std::string mWords; Base() { mWords = "blahblahblah" } }; class Foundation { public: Write( std::string text ) { std::cout << text; } }; class Child : public Base, public Foundation { DoSomething() { this->Write( this->mWords ); // or Foundation::Write( Base::mWords ); } }; Thanks. Edit: And what if there is ambiguity? The two syntaxes you use in your code ( this->... and qualified names) are only necessary specifically when there is ambiguity or some other name lookup issue, like name hiding, template

I am creating a class which, takes a table from a database, and displays it to a web-page, with as much functionality as possible. One of the things I would like to support, would be having the class detect which columns in the table have a foreign key constraint on them, so that it can then go to those tables, get all of their values and use them in a select-box which is called when you edit those fields, to avoid someone violating foreign key constraints, The main problem is discovering which fields have a foreign key constraint on them, and which tables they are pointing to. Does anyone
