Analysis of two methods of php static page generation

// Method 1, generate a static page based on the template
// The replaceTemplateString function is used to replace the specified string in the template
function replaceTemplateString($templateString) {
// Use Variables to replace
$title = "Article title";
$body = "Here is the body of the article";
// Replace the string specified in the template
$showString = str_replace ( "%title%", $title, $templateString );
$showString = str_replace ( "%body%", $body, $showString );
// Return the replacement result
return $showString;
}
$template_file = " template.html";
$new_file = "new.html";
// Template file pointer
$template_juBing = fopen ( $template_file, "r" );
// File pointer to be generated
$newFile_juBing = fopen ( $ new_file, "w" );
// Method 1, get the overall template content string, replace it and assign it to the new file
$templateString = fread ( $template_juBing, filesize ( $template_file ) ) ;
$showString = replaceTemplateString ( $templateString ); // Replace the string in the template
fwrite ( $newFile_juBing, $showString ); // Write the replaced content into the generated HTML file
// Method 2, read each line of the template content string in a loop, replace it and add it to the new file in turn
while ( ! feof ( $template_juBing ) ) { // The feof() function detects whether the end of the file has been reached. Returns TRUE if the file pointer reaches the end or an error occurs. Otherwise, return FALSE (including socket timeout and other situations).
$templateString = fgets ( $template_juBing ); // fgets(file,length) reads a line from the file pointer and returns a string up to length - 1 bytes long, including newlines. If length is not specified, it defaults to 1K, or 1024 bytes.
$showString = replaceTemplateString ( $templateString );
fwrite ( $newFile_juBing, $showString ); // When writing content to the opened pointer file for the first time, the original content in the pointer file will be replaced. Before the file pointer is closed, If the fwrite function adds content, it will close the file pointer after the added content
}
*/
//
fclose ( $newFile_juBing );
fclose ( $template_juBing ); Relationship with static pages
Usually, after adding a piece of information in the database, a static page of the information is generated, so it is best to add a field in the database table to store the path file name of the corresponding static page to facilitate future modifications. Delete
 Template replacement
 Generally speaking, if you need to modify the template of a static HTML page, the usual approach is to delete all the generated HTML pages and then recreate the new HTML page. (Or all re-generated)
Dynamic operations on static pages
Sometimes, some dynamic operations also need to be performed on the static HTML pages created. For example, the click-through rate of each news article in the news system is counted.
You can use an image control with a width and height of 0 pixels to hide a php page to implement the page counter function, such as

Static page of link directory
Usually for systems that use static pages, static HTML files are often generated for the directory page of the link list for visitors to browse
Note This is because every addition or deletion of database information will have an impact on the link list. Therefore, every time database information is added or deleted, the static page of the link directory needs to be updated.
Paging design can be completed by creating multiple static pages with linked directories.

// Method 2, generated based on the buffer
ob_start (); // When the buffer is activated and there is ob_end_clean(), all non-file output is printed The header information will not be printed to the page, but will be saved in the internal buffer. If there is no ob_end_clean(), the information is both stored in the internal buffer and printed
