modCLI

modCLI is a wrapper for the MODX Revolution Processors, allowing you to pretty much do anything from the commandline that you would normally do within the manager.

To use modCLI, simply download the modcli.php file and put it in the MODX_BASE_PATH of your installation. Next open up the console or terminal, and start firing some commands at it.

Why objects (usually) use less memory than arrays in PHP

This is just a small post in response to [this tweet][tweet] by Julien Pauli (who by the way is the release manager for PHP 5.5). In the tweet he claims that objects use more memory than arrays in PHP. Even though it can be like that, it's not true in most cases. (Note: This only applies to PHP 5.4 or newer.)

The reason why it's easy to assume that objects are larger than arrays is because objects can be seen as an array of properties and a bit of additional information (like the class it belongs to). And as array + additional info > array it obviously follows that objects are larger. The thing is that in most cases PHP can optimize the array part of it away. So how does that work?

The key here is that objects usually have a predefined set of keys, whereas arrays don't:

	<?php
	if($modx->context->get('key') != "mgr"){
	/* grab the current langauge from the cultureKey request var */
	switch ($_REQUEST['cultureKey']) {
	case 'en':
	/* switch the context */
	$modx->switchContext('en');
	break;
	default:
	/* Set the default context here */

	set nocompatible " Disable vi-compatibility
	set t_Co=256

	colorscheme xoria256
	set guifont=menlo\ for\ powerline:h16
	set guioptions-=T " Removes top toolbar
	set guioptions-=r " Removes right hand scroll bar
	set go-=L " Removes left hand scroll bar
	set linespace=15

	FROM ubuntu:13.10

	RUN apt-get update

	# nginx
	RUN DEBIAN_FRONTEND=noninteractive apt-get -y install nginx
	RUN echo "daemon off;" >> /etc/nginx/nginx.conf

	# php5-fpm
	RUN DEBIAN_FRONTEND=noninteractive apt-get -y install php5-fpm

	<?php

	$default = realpath(dirname(__FILE__).'/core/lexicon/en').'/';
	$local = realpath(dirname(__FILE__).'/core/lexicon/nl').'/';
	$showSame = false;

	// find default files
	$theFiles = array();
	if($handle = opendir($default)) {
	while(false !== ($file = readdir($handle))) {

	<?php
	// Add RTE for introtext if richtext option is enabled for the resource
	// check "OnDocFormRender" event

	$modx->regClientStartupHTMLBlock('<script>Ext.onReady(function() {
	if(MODx.loadRTE) MODx.loadRTE("modx-resource-introtext");
	});</script>');
