When looping within a Blade template, a $loop variable will be available inside of your loop. This variable provides access to some useful bits of information such as the current loop index and whether this is the first or last iteration through the loop:...
如 {{ $variable }},你可以将其类比为 ,但是 Blade 模板代码的功能要更强大,通过 {{}} 语法包裹渲染的 PHP 变量会通过 htmlentities() 方法进行 HTML 字符转义,从而避免类似 XSS 这种攻击,提高了代码的安全性,所以 {{ $variable }} 编译后的最终代码是:...
When iterating over a LazyCollection instance within a Blade template, the $loop variable is no longer available, as accessing this variable causes the entire LazyCollection to be loaded into memory, thus rendering the usage of lazy collections pointless in this scenario....

5.5 版本之前,MySQL本身只支持一种表间关联方式,就是嵌套循环(Nested Loop Join)。如果关联表的数据量很大,则join关联的执行时间会非常长。在5.5以后的版本中,MySQL通过引入BNLJ算法来优化嵌套执行。 mysql底层join实现只支持一种算法:嵌套循环连接(Nested-Loop Join),nested-Loop-Join有三种变种: ...

To handle multi-levels menus, loop through all the menu items to put them on the right levels, for example.You can use the MenuItem::parent() method to retrieve the parent instance of that menu item:$items = Menu::slug('foo')->first()->items; $parent = $items->first()->parent(...
