We know that when using PHP for website development, the execution results are generally output directly to the browser. In order to use PHP to generate static pages, you need to use the output control function to control the cache area in order to obtain the contents of the cache area, and then output it to the static HTML page file. To achieve static website.
The idea of generating a static page in PHP is: first turn on the cache, and then output the HTML content (you can also include the HTML content in the form of a file through include), then obtain the content in the cache, clear the cache, and use the PHP file read and write functions to The cached content is written to the static HTML page file. Tutorial on reading and writing PHP files?
The process of obtaining the output cached content to generate a static HTML page requires the use of three functions: ob_start(), ob_get_contents(), and ob_end_clean().
Knowledge points:
1. The ob_start function is generally used to enable caching. Note that there cannot be any output before using ob_start, such as spaces, characters, etc.
2. The ob_get_contents function is mainly used to obtain the content in the cache and return it in the form of a string. Note that this function must be called before the ob_end_clean function, otherwise the cache content cannot be obtained.
3. The ob_end_clean function mainly clears the contents of the cache and closes the cache. It returns True if successful and False
if failed. PHP output control function (Output Control) has many applications, which will be expanded in the future.
At this point, the method of using PHP to generate static HTML pages to achieve static website has been introduced. You can choose different static methods according to the actual situation and needs.
