Application and principles of generating HTML files using php

To generate an html page, we need to use the file system operation functions, including fopen, fread, filesize, fwrite, and fclose. These are basically used, such as deleting and creating directories, let's take a look.

1. PHP file operation functions. (Fopen, fread, filesize, fwrite, fclose)

2. unlink () and mkdir () delete functions.

-------------------------------------------------------------

1. PHP file operation functions
(1) fopen open the file function. R/W/
Format: fonpen (path and file name, open mode );

(2) fread reads the file content.
Format: fread (open file, end location );

(3) filesize: the size of the file to be read, measured in bytes.
Format: filesize (path and file name );

(4) fwrite writes the file content.
Format: fwrite (path and file name, written content );

(5) Close the opened file.
Format: fclose (path and file name );

-------------------------------------------------------------

2. unlink (); mkdir (); delete a function

Unlink (); delete a file Function
Format: unlink (path and file );

Mkdir (); delete a directory Function
Format: mkdir (path and directory name );

-------------------------------------------------------------

Instance operation:

The Code is as follows:

Copy code

<? Php $ Title = "New title "; $ Content = "new content www. bKjia. c0m "; $ Fp = fopen ("tmp.htm", "r"); // open the file in read-only mode. $ Str = fread ($ fp, filesize ("tmp.htm"); // read the file content. Format: fread (open file, end position );. $ Str = str_replace ("{title}", $ title, $ str); // Replace the path file content in the str variable with a new value. $ Str = str_replace ("{content}", $ content, $ str ); Fclose ($ fp); // Replace the template content with the above. $ Id = "hello "; $ Path = $ id. '.htm '; $ Handle = fopen ($ path, "w"); // The path to open the news in writing mode. Fwrite ($ handle, $ str); // write the replaced content into the generated HTML file. Fclose ($ handle ); Echo "generated successfully "; ?>

For example, find an html generation class

The Code is as follows:

Copy code

<? Php //-------------------------------------------------------------------------- // File name: html. class. php // Description: www. bKjia. c0m: class for generating static pages // Requirement: PHP5 // // Copyright (C), cricket, 2013, All Rights Reserved. //-------------------------------------------------------------------------- Class myHtml { // Generate the html file path Private $ html_dir = "./"; // Html file name Private $ html_name; // Generate the location name of the html file Public $ path; // Cache content Private $ content; // File handle Private $ handle; // Memory pointer Private $ accesses; // Constructor Public function _ construct ($ html_dir = "", $ html_name = "") { $ This-> accesses ++; // Create a folder if the file path does not exist If (opendir ($ html_dir) = 0) { Mkdir ($ html_dir ); } $ This-> html_dir = $ html_dir! = ""? $ Html_dir :"./"; $ This-> html_name = $ html_name! = ""? $ Html_name: substr (basename (_ FILE _), 0, strrpos (basename (_ FILE _), "."). ". html "; $ This-> path = ($ this-> html_dir {strlen ($ this-> html_dir)-1} = "/") ? ($ This-> html_dir. $ this-> html_name) :( $ this-> html_dir. "/". $ this-> html_name ); Ob_start (); } // Destructor Public function _ destruct () { $ This-> accesses --; Ob_end_clean (); } // Generate an html page Function tohtml () { $ This-> content = ob_get_contents (); If (is_file ($ this-> path )){ @ Unlink ($ this-> path ); } $ Handle = fopen ($ this-> path, "w "); If (! Is_writable ($ this-> path )){ Return false; } If (! Fwrite ($ handle, $ this-> content )){ Return false; } Fclose ($ handle); // close the pointer Return $ this-> path; } } /* $ Html = new myHtml ("./", "z.htm "); Print "static page program "; $ Html-> tohtml (); */ ?>
