问题 I would like to know what is the best way to create next/previous buttons for an entry in the database. Let's say we have a table with images and every image has an ID and a Path. If the current image has ID equal to "9" how can I get the next and the previous IDs? I already found a solution for this right here https://stackoverflow.com/a/8874382 but this seems to be the latest choice.

Call static method from a string name in PHP

阅读更多关于 Call static method from a string name in PHP

问题 I need to call a static method of a class, but I only have a classname, not an instance of it. I am doing it this way. $class = new "ModelName"; $items = $class::model()->findAll(); It works on my computer, but when I move to the server, it throws an unexpected T_PAAMAYIM_NEKUDOTAYIM , so I think it actually expects model to be a variable instead of a method. PS: If it helps, it's Yii framework, so if there's another way to call the find() functions, it's ok to me. Thanks in advance 回答1: This

问题 I am creating temporary table to hold some dates in first query. And in second query I try to join with those dates... and than i get following error: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active.
