We know that using PHP for Web development, the general implementation of the results of direct output to the browser, in order to use PHP to generate static pages, you need to use the output control function to control the buffer, in order to obtain the contents of the buffer, and then output to the static HTML page file to achieve the site static.
The idea of PHP generating static pages is to first turn on the cache, then output the HTML content (you can also include the HTML content as a file via include), then get the contents of the cache, and then empty the cache and write the cached content to a static HTML paging file through the PHP file read-write function. PHP file reading and writing tutorial?
The process of getting the cached content of the output to generate a static HTML page requires three functions: Ob_start (), ob_get_contents (), Ob_end_clean ().
Knowledge Points:
1, Ob_start function is generally used to open the cache, note that there can be no output before using Ob_start, such as spaces, characters and so on.
2. The Ob_get_contents function is primarily used to get the contents of the cache to be returned as a string, note that this function must be called before the Ob_end_clean function, otherwise it will not get cached content.
3, the Ob_end_clean function is mainly to empty the contents of the cache and close the cache, success will return true, failure will return false
There are many applications for the PHP output control function, which will be expanded in the future.
At this point, the use of PHP to generate static HTML pages to achieve the static site method is finished, according to the actual situation and needs you can choose a different static method.
