This is the page that needs to be replaced
The static of the PHP page is very necessary, especially in the CMS system, some content once generated, basically will not change, then if the page is static with HTML, it will undoubtedly reduce the burden of Service parsing PHP page. The following is a book to learn about the static PHP technology, record for a rainy-night.
Whether using a framework or a simple script, the principle is basically the same: the use of PHP for file operations, replacing the dynamic elements in HTML templates, not only to improve the user's access speed can also make PHP and HTML separation, so that the code is more maintainable.
File operation function used:
fopen ()--------------------open a file function has two parameters: 1. The path and file name of the open file 2. The mode in which the file was opened (in string form) used here R and W R for Read only W for write only
Feof ()--------------------read the file until the end of the file this function returns True at the end of the file, so you can use while to know when to finish reading the file; The function has a parameter, 1. Open file pointer
Fwiter ()--------------------write the contents of the file, the function has three parameters: 1. File name to write 2. Content written 3. (optional) Maximum number of characters written
Fclose ()------------------------close the file; You must close the file after you have finished all the operations;
Note: You need to pay attention to the path of the file, and the permissions required to read the file;
PHP Code:
<?PHPHeader("Content-type:text/html,charset=utf-8");/******php static *******/ classtexthtml{ Public functionFwritehtml ($r){ /*PHP page Static technology * $r [array]; *route=> generate the file name and path *html=> the static resource that needs to be read *stsyem=> the label to replace *content=> label replacement content * */ $cfill=fopen($r["HTML"], "R");//the Read file name $cfillnew=fopen($r["Route"], "w"); while(!feof($cfill)){ $row=fgets($cfill);
$res=Str_replace($r["Stsyem"],$r["Content"],$row);//Replace content
fwrite($cfillnew,$res);//Writing HTML files } /*Close File*/ fclose($cfill); fclose($cfillnew); } } $f=Newtexthtml; $fillname=Microtime().". html; $content= "This is a page static technology"; $r["route"] =$fillname; $r["html"] = "index.html"; $r["Stsyem"] = "%demo%"; $r["content"] =$content; $f->fwritehtml ($r);?>
The final results are as follows:
