Hola, tengo esta clase para aplicar plantillas a mis php, pero me gustaria que me digerais si puede provocar sobrecarga en el servidor usarla, en caso de que sea perjudicial hay alguna alternativa?
Código PHP:
class plantilla{
function plantilla($template_file){
global $theme;
$this->tpl_file = 'themes/'.$theme.'/templates/' . $template_file . '.tpl';
}
function asigna_variables($vars){
$this->vars= (empty($this->vars)) ? $vars : $this->vars . $vars;
}
function muestra(){
if (!($this->fd = @fopen($this->tpl_file, 'r'))) {
sostenedor_error('error al abrir la plantilla ' . $this->tpl_file);
} else{
$this->template_file = fread($this->fd, filesize($this->tpl_file));
fclose($this->fd);
$this->mihtml = $this->template_file;
$this->mihtml = str_replace ("'", "\'", $this->mihtml);
$this->mihtml = preg_replace('#\{([a-z0-9\-_]*?)\}#is', "' . $\\1 . '", $this->mihtml);
reset ($this->vars);
while (list($key, $val) = each($this->vars)) {
$$key = $val;
}
eval("\$this->mihtml = '$this->mihtml';");
reset ($this->vars);
while (list($key, $val) = each($this->vars)) {
unset($$key);
}
$this->mihtml=str_replace ("\'", "'", $this->mihtml);
echo $this->mihtml;
}
}
}
