6. Self-compile PHP and integrate Ngnix nginx php5.6 nginx php cache php nginx An

When a request is received, if it is a PHP request, it is sent to the PHP interpreter for processing and the result is returned to the client. Nginx generally sends the request to the fastcgi management process for processing. The fascgi management process selects the cgi sub-process to process the result and returns it to nginx. 1. First, let’s have a preliminary understanding of the operating principles of FastCGI and Ngnix+FastCGI 1. Apache+PHP and ngnix+php The difference between apache and apache is that it generally treats php as
7. PHP realizes page staticization php7 php environment builds php from entry to proficiency
Introduction: php:PHP realizes page staticization: Why should page staticization be done? 1. Dynamic file execution process: syntax analysis-compile-run 2. Static files do not need to be compiled, which reduces the running time of the server script and reduces the server's response time. It is run directly and the response speed is fast; if some content in the page does not change frequently, staticizing the dynamic page is a very effective acceleration method. .

When the page contains a PHP script, the server will hand it over to the PHP interpreter for interpretation and execution, and then pass the generated html code back to the client. The client's browser interprets the html code, and finally forms a web page format. Page. What PHP can do PHP is mainly used in three areas: PHP analyzer, a WEB server and a WEB browser.

Introduction: Fast and Furious 7 box office real-time updates: Fast and Furious 7 box office real-time updates: Fast and Furious 7 box office real-time updates Real-time updates pursue program speed, not programming speed: 1. Use embedded HTML code instead of PHP's echo statement. Because PHP is an embedded Web programming language, HTML code and PHP code can be embedded in each other. Many programmers worry that excessive use of "" to embed PHP code in HTML code will call the PHP interpreter multiple times, thereby reducing the running speed of PHP code, so they would rather use PHP's echo statement to output HTML code instead of directly using HTML code. But the fact is exactly the opposite. Each PHP page only calls PHP explanation
