())Because the array_merge function merges the arrays of the same string key names, you must first use the array_value fetch values and then merge them.If the second dimension is a numeric key name, such as:Array (Array ( ' A1 '), Array (Array (array ( ' A5 '),); So that's it for you:Array ())2 array_walk_recursive Function MethodWith the array_walk_recursive () function, it is very flexible to convert an array of any dimension into a one-dimensional array.function( $result) { Array

How to get a control of the long and high, I believe many friends first saw this problem will feel very simple, directly inside the OnCreate call getwidth, getmeasuredwidth can not be obtained, but, in fact, there is no simple, not letter, You can try it, in the OnCreate, you can't get the long width value, always 0.
Friends familiar with the view drawing process should see it at a glance, in the OnCreate, our control is not actually painted well, in other words, when the OnCreate method is fini
The entry page is the first entry for visitors to the site, the first visited page on each visit. The portal page as the first page of the site visitors, its quality can directly see whether the site optimization is reasonable. Today, we will analyze the four dimensions of traffic, new visitors, attraction and transformation of the portal page.
Dimension One: Flow analysis
Traffic analysis focuses on the site's browsing volume, number of visitors an
function optimization of important means, of course, there are many can do the details of optimization, such as try not to check the fields you want to be approved as empty, as far as possible to suppress the connection of joint query to number type and so on.By the way, if you do a dimension table, do a materialized attempt, you go to query the original table when the speed will surely add? The answer is "no", an important thing you have to do, even if you tell Oracle that it can actively opti
