Compactando Saida HTML CodeiGniter - Parte 2

Dica rápida mas boa.

O que vai acontecer é que a saida do codigo HTML gerado pelas views do CodeiGniter vão ser mais compactas, removendo espaços desnecessários, com isso vai se ganhar mais performance, e também dá uma dificultada na visualização do código html.



application/config/config.php

$config['enable_hooks'] = TRUE;

Cole o seguinte conteudo no arquivo

application/config/hooks.php

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

/*

| -------------------------------------------------------------------------

| Hooks

| -------------------------------------------------------------------------

| This file lets you define "hooks" to extend CI without hacking the core

| files.  Please see the user guide for info:

|

*/

$hook['display_override'][] = array(

'class' => '',

'function' => 'compress',

'filename' => 'compress.php',

'filepath' => 'hooks'

);

/* End of file hooks.php */

/* Location: ./application/config/hooks.php */

Então agora crie o arquivo compress em 

application/hooks/compress.php

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

 

function compress()

{

$CI =& get_instance();

$buffer = $CI->output->get_output();

 

$search = array(

'/\n/', // replace end of line by a space

'/\>[^\S ]+/s', // strip whitespaces after tags, except space

'/[^\S ]+\</s', // strip whitespaces before tags, except space

'/(\s)+/s' // shorten multiple whitespace sequences

 );

 

$replace = array(

' ',

'>',

'<',

'\\1'

 );

 

$buffer = preg_replace($search, $replace, $buffer);

 

$CI->output->set_output($buffer);

$CI->output->_display();

}

 

/* End of file compress.php */

/* Location: ./system/application/hools/compress.php */
