Then it adds this temporary value into the resulting array under the same string key or numeric index. Let’s test new functionality... $ php -r ‘var_dump(test_scale([2, 2.0, “x” => [“2”]], 3));’ array(3
您可以使用来自index.php的新类定义。这将是一个微小的变化。更新index.php如下: //Partial code listing for index.php include_once "classes/Page_Data.class.php"; $pageData = new Page_Data(); //delete or comment out the previous object //$pageData = new stdClass(); //no changes below th...
In this case, you may consider calling asArray() while using Active Record to query data so that the retrieved data is represented as arrays instead of bulky Active Record objects. For example,class PostController extends Controller { public function actionIndex() { $posts = Post::find()->...
Fix bug GH-11154 (Negative indices on empty array don't affect next chosen index). Fix bug GH-8846 (Implement delayed early binding for classes without parents). Fix bug #79836 (Segfault in concat_function). Fix bug #81705 (type confusion/UAF on set_error_handler with concat operation)...
So in this case, you get back $row, you grab the table name by getting the first item in the array, at index 0, and then you print that with echo. There’s just one other wrinkle here: those curly braces inside the string passed to echo. What’s up with those? Well, you could...

The yii\helpers\Url::to() method also supports creating URLs that are not related with particular routes. Instead of passing an array as its first parameter, you should pass a string in this case. For example,use yii\helpers\Url; // currently requested URL: /index.php?r=admin%2Fpost%...
