2 Today I have to share is not refreshing the page under the premise of using PHP + jQuery + Ajax multi-picture upload results. Users only need to click to select the picture you want to upload, and then the picture is automatically uploaded to the server and displayed on the page.

In this paper we use an Ajax form submission plugin: jqery.form.js, have an expert to modify a few lines of code and renamed: jquery.wallform.js, directly used.

6 There in a television program called the flap a lottery sweepstakes form for the time being, there is a stage wall, wall to place several large squares, host or sweepstakes who opened the box corresponding to announced the winning results.

3 In this paper, Monopoly game as the background, the integrated use of jQuery and PHP knowledge, designed to throw the dice points to achieve the effect of the draw, of course, lottery probability is controllable, developers can use this example to some modifications to the site the raffle scene.

HTML

In this paper, the simulation Login Open Source China (oschina) as an example, and share cURL use.

PHP's curl () in terms of efficiency crawled pages is relatively high, and supports multi-threading, and file_get_contents () would be slightly more efficient, of course, need to open when using curl under the curl extension.

10 In php projects, often use to label some filtering regular expressions, collections for spare.

2 Sometimes we need to project a specific PHP information is encrypted, encrypted string that is generated by an encryption algorithm, the encrypted string can be decrypted by the decryption algorithm, to facilitate the decrypted program information is processed.

The most common applications in the user login, and some API data exchange scenarios.
I included some of the more classic PHP code encryption and decryption functions for everyone to share. Cryptographic principles generally through some encryption and decryption algorithms, the key is added to the algorithm, encryption and decryption finally get results.

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.

3 Use cPHP built-in function memory_get_usage () to return the PHP script is currently assigned to the amount of memory, in bytes (byte). In the WEB actual development, these functions are useful, we can use it to debug PHP code performance.

memory_get_usage () function returns the memory usage, memory_get_peak_usage () function returns the memory usage peaks, getrusage () returns CUP usage. But one thing Please note that you need to run on Linux in these functions.
