PHP Learning Notes (37) The variable adjuster in Smarty is used

Basically Smarty's built-in regulator is already rich enough to meet simple requirements. To find out or add a new adjuster after you've learned about it

init.smarty.php

<?php

	define ("ROOT", ".");

	Problem solving: Warning:strftime () [Function.strftime]:
	date_default_timezone_set ("Asia/shanghai");
	Include ROOT. " /libs/smarty.class.php ";
	
	$TPL = new Smarty ();
	
	Smarty initialization
	$tpl->template_dir=root. " /templates/";
	$tpl->compile_dir=root. " /templates_c/";
	The configuration file location
	$tpl->config_dir=root. " /configs/";
	$tpl->left_delimiter= "<!--{";
	$TPL->right_delimiter= "}-->";

	require ' init.smarty.php ';
	
	$title = "This is a text title";
	$str = "I am A-Bay boy!";
	
	
	$tpl->assign ("title", $title);
	$TPL->assign ("str", $STR);
	$tpl->assign ("Strc", $title);
	Template file name can be arbitrarily defined: For example: MYSMARTY.TPL only content is HTML can be
	$tpl->display ("mysmarty.html");

Add the following file to the Smarty Plugin plugins folder for custom adjuster use

modifier.tocut.php


<?php
	function Smarty_modifier_tocut ($str, $star, $len) {
		$str =substr ($str, $star, $len);
		return $str;
	}
 
modifier.tochange.php

<?php
	function Smarty_modifier_tochange ($str, $mod) {
		switch ($mod) {case
			"lower":
				$str = Strtolower ($STR);
				break;
			Case "Upper":
				$str =strtoupper ($STR);
				break;
			Case "a":
				$str =ucfirst ($STR);
				break;
		return $str;
