We know that PHP is used for website development, and the execution results are generally output directly to the browser. In order to use PHP to generate a static page, you need to use the output control function to control the cache area in order to obtain the content of the cache area, and then output it to a static HTML page file to achieve static website.
The idea of PHP generating a static page is: first turn on the cache, 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 pass PHP file reading and writing functions write cached content into static HTML page files. Tutorial on reading and writing PHP files?
The process of obtaining the output cache content to generate a static HTML page requires the use of three functions: ob_start(), ob_get_contents(), 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.
The PHP output control function (Output Control) has many applications and will be used in the future. unfold one after another.
At this point, the method of using PHP to generate static HTML pages to achieve website staticization has been introduced. You can choose different staticization methods according to the actual situation and needs.
