Introducing the method of generating static PHP website pages_PHP Tutorial
There are two ways to make the page static, one is pseudo-static, which is url rewriting, and the other is you really make it static. The following introduces the method of staticizing pages in PHP.
In PHP website development, for website promotion and SEO needs, the website needs to be statically processed as a whole or partially. There are many ways to generate static HTML pages in PHP, such as using PHP templates, caching, etc. to realize the page. Staticization, today I will discuss the method of generating static pages in PHP in the form of a PHP tutorial.
What is PHP static
The simple understanding of PHP static is to make the website generated pages displayed in front of visitors in the form of static HTML. PHP static is divided into pure static The difference between the two is that PHP generates static pages with different processing mechanisms.
How to generate static HTML pages with PHP
1. Use PHP templates to generate static pages
PHP templates to achieve staticization It is very convenient, such as installing and using PHP Smarty to achieve static website.
2. Use PHP file reading and writing functions to generate static pages
PHP generate static page example code
<ol class="dp-c">
<li class="alt"><span><span><? </span></span></li><li><span class="vars">$out1</span><span> = "<html><head><title>PHP网站静态化教程</title></head> </span></span></li>
<li class="alt"><span><body>欢迎访问PHP网站开发教程网www.leapsoul.cn，本文主要介绍PHP网站页面静态化的方法 </span></li>
<li><span></body></html>"; </span></li>
<li class="alt">
<span> </span><span class="vars">$fp</span><span> = </span><span class="func">fopen</span><span>(</span><span class="string">"leapsoulcn.html"</span><span>,</span><span class="string">"w"</span><span>); </span>
</li>
<li>
<span class="keyword">if</span><span>(!</span><span class="vars">$fp</span><span>) </span>
</li>
<li class="alt"><span>{ </span></li>
<li>
<span class="func">echo</span><span> </span><span class="string">"System Error"</span><span>; </span>
</li>
<li class="alt">
<span class="func">exit</span><span>(); </span>
</li>
<li><span>} </span></li>
<li class="alt">
<span class="keyword">else</span><span> { </span>
</li>
<li>
<span>fwrite(</span><span class="vars">$fp</span><span>,</span><span class="vars">$out1</span><span>); </span>
</li>
<li class="alt">
<span>fclose(</span><span class="vars">$fp</span><span>); </span>
</li>
<li>
<span class="func">echo</span><span> </span><span class="string">"Success"</span><span>; </span>
</li>
<li class="alt"><span>} </span></li>
<li><span>?> </span></li>
</ol>3. Use The PHP output control function (Output Control) generates static pages
The output control function (Output Control) uses and controls cache to generate static HTML pages, and also uses PHP file reading and writing functions.
PHP generates static page example code
<ol class="dp-c">
<li class="alt"><span><span><? </span></span></li><li><span>ob_start(); </span></li><li class="alt"><span class="func">echo</span><span> </span><span class="string">"<html>"</span><span>. </span></span></li>
<li>
<span class="string">"<head>"</span><span>. </span>
</li>
<li class="alt">
<span class="string">"<title>PHP网站静态化教程</title>"</span><span>. </span>
</li>
<li>
<span class="string">"</head>"</span><span>. </span>
</li>
<li class="alt">
<span class="string">"<body>欢迎访问PHP网站开发教程网www.leapsoul.cn，本文主要介绍PHP网站页面静态化的方法</body>"</span><span>. </span>
</li>
<li>
<span class="string">"</html>"</span><span>; </span>
</li>
<li class="alt"><span> </span></li>
<li>
<span class="vars">$out1</span><span> = ob_get_contents(); </span>
</li>
<li class="alt"><span>ob_end_clean(); </span></li>
<li>
<span class="vars">$fp</span><span> = </span><span class="func">fopen</span><span>(</span><span class="string">"leapsoulcn.html"</span><span>,</span><span class="string">"w"</span><span>); </span>
</li>
<li class="alt">
<span class="keyword">if</span><span>(!</span><span class="vars">$fp</span><span>) </span>
</li>
<li><span>{ </span></li>
<li class="alt">
<span class="func">echo</span><span> </span><span class="string">"System Error"</span><span>; </span>
</li>
<li>
<span class="func">exit</span><span>(); </span>
</li>
<li class="alt"><span>} </span></li>
<li>
<span class="keyword">else</span><span> </span>
</li>
<li class="alt"><span>{ </span></li>
<li>
<span>fwrite(</span><span class="vars">$fp</span><span>,</span><span class="vars">$out1</span><span>); </span>
</li>
<li class="alt">
<span>fclose(</span><span class="vars">$fp</span><span>); </span>
</li>
<li>
<span class="func">echo</span><span> </span><span class="string">"Success"</span><span>; </span>
</li>
<li class="alt"><span>} </span></li>
<li><span>?> </span></li>
</ol>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.
