PHP template engine smarty-display render text string

$smarty=$this->smarty;
$smarty->assign('foo','value');

$template_string = 'display {$foo} here';

// compiles for later reuse

$smarty->display('string:'.$template_string);

// compiles every time

$smarty-& gt;display ('eval:'.$template_string);

The above has introduced the PHP template engine smarty-display to render text strings, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
