PHP Learning Notes (33) Implementation of PHP custom template engine

Implement a simple template engine yourself: Aspects of PHP logic and the separation of the page

Template class:

<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd" >
 

Page to call:

<?php
	include "mytpl.class.php";
	
	$TPL = new Mytpl ("./templates/", "./templates_c");
	Program Simple way
	$title = "This is a text title, get from the database";
	$content = "This is content";
	
	$tpl->assign ("title", $title);
	$tpl->assign ("content", $content);
	
	$tpl->display ("mysmarty.html");
? >
 

Convert page:

<?php header ("Contenttype=text/html;charset=utf-8");
		Class mytpl{private $template _dir;
		Private $compile _dir;
		Private $tpl _vars=array (); /** * Template path and compiled path * @param template path $template _dir * @param compile path $compile _dir/function __construct ($template _ Dir= "./templates", $compile _dir= "./templates_c") {//Add final/$this->template_dir = RTrim ($template _dir, "/"). '
			/'; $this->compile_dir = RTrim ($compile _dir, "/"). '
		/';; /** * input variable into array * @param unknown_type $tpl _var * @param unknown_type $value/Public Function assign ($tpl _var, $value =null)
			{if ($tpl _var!= "") {$this->tpl_vars[$tpl _var]= $value; /** * Displays the last generated file * @param template file $fileName/Public function display ($fileName) {//template file $tplfile =
			$this->template_dir. $fileName;
			if (!file_exists ($tplfile)) {return false; //compile filename $confileName = $this->compile_dir. " Com_ ". $fileName.".
			
			PHP "; if (!file_exists ($confileName) | | filemtimE ($confileName) <filemtime ($tplfile)) {$repContent = $this->tpl_replace (file_get_contents ($tplfile));
			File_put_contents ($confileName, $repContent);
		}//display output include $confileName; /** * Replace template return * Enter description here ... * @param unknown_type $content/Private Function Tpl_replac
			E ($content) {//matching regular expression $pattern = Array ('/\<{\s*\$ ([a-za-z_\x7f-\xff][a-za-z0-9_\x7f-\xff]*) \s*\}\>/i ');
			$replacement = Array (' <?php echo $this->tpl_vars[' ${1} ';?> ');
			$repContent = Preg_replace ($pattern, $replacement, $content);
		return $repContent;
 }}?>
