首先,使用Laravel的辅助函数array_combine()将数组的值作为键名,生成一个新的关联数组。这将创建一个新的数组,其中键名是原始数组的值。 代码语言:txt 复制 $array = ['apple', 'banana', 'orange']; $randomKeys = array_combine($array, $array); 然后,使用Laravel的辅助函数array_keys()获取新数组的...

$array=array_collapse([[1,2,3],[4,5,6],[7,8,9]]); // [1, 2, 3, 4, 5, 6, 7, 8, 9] array_divide 函数返回两个数组,一个包含原数组的所有键,另外一个包含原数组的所有值: list($keys,$values)=array_divide([‘name’=>‘Desk’]); // $keys: [‘name’] // $values: [...
array_divide 函数返回两个数组,一个包含原本数组的键,另一个包含原本数组的值:list($keys, $values) = array_divide(['name' => 'Desk']); // $keys: ['name'] // $values: ['Desk']array_dot()#array_dot 函数把多维数组压制成一维数组,并用「点」式语法表示深度:...

\?\}/', $this->route->uri(), $matches)这句话作用是把可选参数名值提取出来,并通过array_fill_keys()处理得到如下的命名数组: optionals = array ( 'user' = null, 'name' = null ) 而compile()中的preg_replace('/\{(\w+?)\?\}/', '{$1}', $this->route->uri())这句话的作用就...
