I. Overview
PHP tutorial-excelreader is a PHP class that reads the contents of an Excel XSL file.
It's download URL: http://sourceforge.net/projects/phpexcelreader/

Contains two required files: Oleread.inc, reader.php. Other files are an application example, Readme file etc
Second, the use of documents
First, contains the reader class file: require_once "reader.php";

" means to expand the above calculation to two-dimensional space based on the influence of horizontal interpolation, and then calculate the influence of vertical interpolation. The dual-cube interpolation algorithm can produce relatively clear picture quality, but the computing workload also increases. This algorithm is most commonly used in many image processing software today, such as Photoshop, after effects, avid, Final Cut Pro, etc. In order to get better image quality, many new algorithms
technology, DSL2 integrated engine, 1.2 MB XGLite/4 MB General MIDI audio library, and allows users to load custom sound settings to SoundMAX synthesizer; you can even use some third-party software applications to create your own MIDI sequence and DLS sound settings. You can adjust the CPU usage within the range of 20%-80% when playing MIDI.
All of these outstanding features have boosted the performance of the common AC "97 sound card, so that numerous users of the AC" 97 sound card are excited

Supports dynamic VLANs that are to be used in the future.

QoS
Data frames can be reclassified Based on the 802.1 p CoS value or the default CoS value specified by the network administrator for each port.
On the hardware, each output port supports four queues.
The WRR queue algorithm ensures that low-priority ports are not ignored.
Strict priority settings
At present, I want to create a mobile version of the mall. This problem occurs when designing the database .. for example, a dress has red, white, blue, red, X, XL, and XLL sizes. White, S, M, X, XL, Blue, M, X, XL has never been satisfied with the database designed by myself. I hope all the ways are great... at present, I want to create a mobile version of the m

(3) The scope of external variables is from the definition point to the end of this file. If the function before defining a vertex needs to reference these external variables, you must describe the referenced external variables in the function. The external variables are described as follows:

This is because the Xen-related software library is installed in the/usr/local/lib directory, the system cannot be found.

PHP scenario, you need to convert the array to a JSON string, you need to use PHP's own json_encode function;But when the array contains Chinese strings, the result of the transfer is the following:1PHP2 3 $TMPARR=Array(4' Name ' = ' trousers ',5' Color ' = ' blue ',6' Size ' = ' XL ',7' title ' and ' Aged mens trousers '8 );9 Ten $tmpJson= Json_encode ($TMPARR); One A Echo $tmpJson;Output: {"name": "\u957f\u88e4", "Color": "Blue", "S
statement is actually a subquery. To demonstrate the use of subqueries in the WHERE clause, assume that you need to display a Sales.SalesOrderDetail record that contains the purchase of a oversized long sleeve logo sweatshirt. The code in Listing 3 satisfies my display requirements by using subqueries. SELECT * FROM [Sales]. [SalesOrderDetail] WHERE ProductID = (SELECT ProductID from [Production]. [Product] WHERE Name = ' Long-sleeve Logo Jersey, XL
Divide and Conquer (Divide and Conquer) algorithm: The problem can be decomposed into sub-problems, each problem can be solved independently, from the solution of sub-problem can build the original problem.Divide: Intermediate points, random points, odd even points, and so on, the problem is decomposed into independent sub-problemsConquer: The solution of sub-problem can be solved by itself, and the final solution of the original problem is constructed from the solution of sub-problemCombine: Ea
information or richer dimensions (eigenvalues). So the network can learn more rich content.
This diagram compares the depth and structure of the three networks, VGG-19, 34-tier "flat networks"-the average 34-story CNN Network, and a 34-layer deep residual network.
In the design of the deep residual network, it is usually a kind of "strive for simplicity" design method, just to deepen the network, all the convolution layer uses the 3x3 convolution kernel, and never design any full connection la

All of these outstanding features give the average AC "97 sound card a performance boost that excites countless AC" 97-card users, as well as triggeri

I watched a video on excel operations by the old K. I am very grateful to the old K for sharing it!
To install the xlrd module, open cmd and enter the command: pip install xlrd to install it. If it has been installed, it is shown as follows:
You can use the following methods to read excel files from xlrd:
''' 1. open the file ''' xl = xlrd. open_workbook (file) ''' 2. Obtain sheet ''' prin
