PHP generates an entire Web site HTML static _php tutorial

In fact, the method of implementation is very simple.

php; " >
 
  

This is only the most basic method, is not very practical, because the site is to be updated, to periodically regenerate the HTML

Here's how I use it:

if (file_exists ("xxx.html"))
{
$time = time ();

File modification time and the current time difference of half an hour, direct to the HTML file, otherwise regenerate HTML
if ($time-filemtime ("xxx.html") < 30*60)
{
Header ("Location:xxx.html");
}
}
Add Ob_start () at the beginning of your service;
Ob_start ();

Detailed content of the page
Add Ob_end_clean () at the end and output this page to a variable
$temp = Ob_get_contents ();
Ob_end_clean ();

Write file
$fp = fopen (' xxx.html ', ' W ');
Fwrite ($FP, $temp) or Die (' Write file error ');

Re-orientation
Header ("Location:xxx.html");

Here is an introduction to some of the functions used:
1, Flush: Flush the contents of the buffer, output.
function format: Flush ()
Description: This function is often used and is highly efficient.
2. Ob_start: Open Output buffer
function format: void Ob_start (void)
Note: When the buffer is active, all non-file header information from the PHP program is not sent, but is saved in the internal buffer. In order to output the contents of the buffer, you can use the contents of the Ob_end_flush () or flush () output buffers.
3. Ob_get_contents: Returns the contents of the internal buffer.
How to use: String ob_get_contents (void)
Description: This function returns the contents of the current buffer and returns FALSE if the output buffer is not activated.
4. Ob_get_length: Returns the length of the internal buffer.
How to use: int ob_get_length (void)
Note: This function returns the length of the current buffer, as with ob_get_contents, if the output buffer is not activated. FALSE is returned.
5. Ob_end_flush: Sends the contents of the internal buffer to the browser, and closes the output buffer.
How to use: void Ob_end_flush (void)
Description: This function sends the contents of the output buffer (if any).
6. Ob_end_clean: Delete the contents of the internal buffer and close the internal buffer
How to use: void Ob_end_clean (void)
Description: This function does not output the contents of the internal buffer but deletes it!
7. Ob_implicit_flush: Turn absolute refresh on or off
How to use: void Ob_implicit_flush ([int flag])
Description: People who have used Perl know the meaning of $|=x, this string can open/close the buffer, and the Ob_implicit_flush function is the same, the default is to close the buffer, open the absolute output, each script output is sent directly to the browser, no longer need to call flush ()
