In PHP programming, recursive calls are often used with static variables. For the meanings of static variables, refer to the PHP Manual. we hope the following code will be more conducive to understanding recursive and static variables. The code is as follows: // The following code will draw a very beautiful leaf// Define the point of view of PIDefine ("PII", M_PI/180 );// Create an image resource and set the background to White. the foreground co

embedded in HTML documents, PHP is executed on the server, making full use of the server performance; the PHP execution engine also stores frequently accessed PHP programs in the memory. when other users access this program again, they do not need to re-compile the program, you only need to directly execute the code in the memory, which is also a reflection of PHP's high efficiency.

This article mainly introduces a Leaf Image drawing example generated by PHP, hoping to help some friends who use PHP for image programming. Effect: Tip: save it to the PHP file and paste it in the browser to see the same picture. The code is as follows: $ Im = imagecreate (670,500 );$ White = imagecolorallocate ($ im, 0xFF, 0xFF, 0xFF );$ G = imagecolorallocate ($ im, 0x00, 0x00, 0x00 );Define ("PII", M_PI/180

Draw a very beautiful leaf. Defines the value of the angle of a PI point Define ("PII", m_pi/180); Creates a new image resource and defines its background as white with a foreground color of black $im = Imagecreate (670,500); $white = Imagecolorallocate ($im, 0xFF, 0xFF, 0xFF); $g = Imagecolorallocate ($im, 0x00, 0x00, 0x00); From the code instantiated below you can tell that the initial value $x, $y, $L, $a not divi

PHP has very powerful functions, all CGI or JavaScript functions can be implemented in PHP, and supports almost all popular databases and operating systems. Here we will introduce PHP Recursive Algorithms in detail. PHP recursive algorithm code: Php // Define the point of view of PI Define ("

Copy Code code as follows: The following code will draw a very beautiful leaf Value that defines the angle of PI one point Define ("PII", m_pi/180); Creates a new image resource and defines its background as white, with a foreground color of black $im = Imagecreate (670,500); $white = Imagecolorallocate ($im, 0xFF, 0xFF, 0xFF); $g = Imagecolorallocate ($im, 0x00, 0x00, 0x00); The code instantiated from the following can be learned that th

recompile the program once again, as long as they execute the code directly in memory, which is one of the most efficient embodiments of PHP. PHP has a very powerful function, all of the CGI or JavaScript features PHP can be implemented, but also support almost all popular databases and operating systems. Here is a detailed introduction to the PHP recursive algorithm. PHP Recursive algorithm code: Copy Code code as follows: Defines the value of a PI-point angle ("

The Network has connected more and more devices. People can obtain information through various access methods. More and more people begin to use new technologies to connect with each other, participate in the workflow together, perform division of labor and collaboration, and learn from each other and make innovations. Sun calls this New Age the age of participation. In this age of participation, participants not only acquire information, but also create and process knowledge and share knowledge
