11 We browse the page to load a large size picture, the picture size is relatively large, we will see the browser to load the picture from top to bottom when the picture will be displayed until the picture is complete on the page, so that the image from the blank area To fully loaded process is more unexpected, the user experience is relatively poor.

We use the solution is to first load a small thumbnail, it may only 1K or so, and according to the required size of fuzzy display, wait until the large size of the picture to download a good and then complete the show large picture. This gives the user the feeling is to load the fuzzy picture, and then become clear picture, picture loading process fluently, greatly improve the user experience.

3 Projects often require some headache functions, as developers should organize its own library, when you need it can be copied. The authors collected dozens of commonly used functions in PHP project, guaranteed to run properly, you just copy and paste into your project.

40 When we want a huge number of data, while the median number have restrictions, such as license plate numbers 5, 10 of a document number, serial number of orders, short URL, etc., we can use the 36-ary calculated not repeat the numbers in line with the median.

We will use 0-Z (0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ) to represent the values ​​0-35, such as the letter Z represents 35. So I want to get a five numbers, the greatest amount of information is 36 5 th, and 36 ^ 5 = 60,466,176, which is equivalent to the maximum number of five decimal numbers: 60466176.
In order to do presentations in this article, we assume that a group of 10 paid a club membership number, membership number by three city ID card encoding +2 +5 bit checksum components. City number with area code indicated as 755 representatives of Shenzhen, five card numbers from card number consisting of 36 hexadecimal, followed by two check code is generated by a certain algorithm is able to use the checksum to verify the card number legitimacy. In this case, we generate 10 card number corresponds to the maximum to meet the 60 million membership number, and is not repeated unique card number.

1 The mobile Internet era, we can pass the information "sweep swept away" feature to easily get in the mobile terminal needs. Today I have to share a WEB function, it is a small floating toolbar on the right side of the page, we can use it to quickly locate the page up and down position, you can eject the micro-channel or two-dimensional code page address two-dimensional code, so like in the phone read on mobile devices and other friends easy access to information.

HTML
First, we prepared the right side of the floating layer content, toolbar has up and down arrow button, and then a "feedback" link, you can click on the feedback information page of your site, there is a two-dimensional code button will pop up a two-dimensional slide on mouse code picture, then we use the two-dimensional code .popPanel to place pictures, .arrowPanel is used to make the direction of the arrow. In this example, I use a background image as a toolbar, the practical application of course we can also add more functions in accordance with the actual needs of the button.

11 With the advancement of technology, two-dimensional code applications more widely, before the site has article describes using jQuery plugin to generate two-dimensional code, and today I share with you how to use PHP to generate two-dimensional code, and how to generate two-dimensional code in the middle with LOGO image.

Use Google API to generate two-dimensional code
Google offers a more comprehensive two-dimensional code generation interface, call the API interface is very simple, the following is the calling code

1 Two-dimensional code applications have penetrated into living and working among us, you only need a mobile phone in front of the two-dimensional code "sweep swept away" to get the corresponding information to help us understand the business, shopping, viewing and so on. This article will introduce a two-dimensional code generation based on jquery plugin qrcode, calling the plug-in page will be able to generate the corresponding two-dimensional code.

qrcode actually realized by using jQuery graphics rendering, drawing support canvas (HTML5) and the table in two ways
