GOOCODE - Find your code/scripts

0 In today's digital age, search engines have become an integral part of our everyday lives. They enable us to explore the vast universe of information available on the internet and find answers to our questions or solutions to our problems in mere seconds. Open source search engine scripts offer users the ability to create and customize their search engines to better suit their specific needs. In this essay, we will delve into the world of open source search engine scripts, examining their benefits, drawbacks, popular examples, and the future outlook of this technology.

0 The internet is vast, and finding specific information can be a challenge. One of the tools that make this easier is search engines. From Google to Bing, these powerful systems sift through the massive amounts of data on the web to deliver the most relevant results. However, with the advent of PHP search engine scripts, web developers can create custom search engines tailored to specific needs or niches.

0 When working with the Unicode character set, use the corresponding function instead of the native string function. For example, if a file is encoded as UTF-8 PHP code, if the strlen() function is wrong, use the mb_strlen() function instead.

If you use substr to intercept Chinese characters, garbled characters will appear, because substr is intercepted in bytes. That is, UTF-8 encoded Chinese, using substr interception, will only intercept 1/3 Chinese, of course, garbled. When UTF-8 is encoded, a Chinese character is 3 bytes. Similarly, different languages in other countries will produce multi-byte strings, so we use mb_strlen() to handle them.

0 Never trust external input, don't trust any data from a data source that is not under your direct control. In actual development, there is always someone intentionally or unintentionally injecting dangerous data into PHP code, so PHP security programming becomes important. Generally, we deal with external input security ideas: filtering input and verifying data.

Filtering input means escaping or deleting characters that are not safe from external data.

0 Recently, due to project requirements, the server was upgraded from CentOS6 to CentOS7, and the corresponding PHP version was also upgraded to PHP5.6. We are familiar with a one-click installation package for LEMP environment, but in this article we will install each component module separately and build a complete PHP operating platform.

The LNMP environment we often refer to is the Linux/nginx/MySQL/PHP combination. What is LEMP? Actually, Nginx is pronounced Engine-X = E. The LEMP package is made up of Linux, nginx, MariaDB/MySQL, and PHP. It seems that LEMP and LNMP are the same. Now, it is customary to call LEMP in the industry. MariaDB is a branch of the community-driven MySQL database. It has more features and better performance, so we installed MariaDB under CentOS7. I already installed CentOS7. Now I just need to install Nginx, MariaDB and PHP.

0 The normal site to bring the kind of parameters may be very long, especially in the printing of paper products such as corporate brochures to be printed on a long url, then very ugly, and few people will go to remember this site, Although it is now possible to use a two-dimensional code to open a long URL. But people can use short URLs to achieve beautiful links, especially those with limited number of applications such as microblogging.

Short URL implementation principle is that there is a data table configuration file will be short URL and the actual URL corresponding, when a short URL request, the program jump to the corresponding actual URL up, in order to achieve the URL of the visit.

24 Danmmu Player is a barrage of Html5 video player. When we watch the video, you can express their views on the video, when you click the Send button, the content will be published in the video screen in the form of paintball issue, and do rolling animation, video barrage function.

6 PHP's serialize a sequence of the variable, the variable type and returns a string expression with a structure, but JSON is a lighter, more user-friendly format for interfaces (AJAX, REST, etc.) for data exchange. In fact, both are in a string manner to reflect a data structure. So what difference does it have between them?

We may see the contents of a database or stored in a text file with a long list of seemingly has a special meaning in the text string some old WEB system. We look carefully will find that it has a data type and structure information, but it is not easy to read manual, it is only suitable PHP program reads. PHP's serialize the array is serialized and stored. We assume that there is such an array:

1 In the previous article, we use HTML5 to listen to the phone in order to achieve a shaking effect. Shake the phone can be applied to many scenarios, such as a shake to change the draw, shake songs, search. In this paper, I will tell you how to use HTML5 + PHP + jQuery to achieve the effect of mobile phone shaking to change clothes.

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. Similar lottery form can also be applied in the WEB, this article will use PHP + jQuery for you to explain how to achieve the flap lottery program.

Draw flap implementation process: Front page offers six squares, followed by the numbers 1-6 represent six different squares, when the draw clicks six squares in a one time, flip to the back of the box to show the winning lottery information.
