PHP – Removing alpha characters from an entire array using closure

May 7, 2013 12:40 pm /

Here’s a quick way to remove all alpha characters from an array using PHP closures (PHP 5.3+)

array_walk($myarray, function(&$element){ $element = trim($element,"ABCDEFGHIJKLMNOPQRSTUVWXYZ"); });

You can also remove all numbers from an array similarly

array_walk($myarray, function(&$element){ $element = trim($element,"0123456789"); });

The variable must be passed by reference in order to change the values of the original array. I really like the addition of closures, which reduces the need to create a new method for simple operations.

Zend Form – Adding a checkbox element with label to the side

February 21, 2013 7:42 pm /

Here’s the fastest way to add a checkbox element with a label to the side of it (inline) using the Zend Framework. By default, the checkbox is put on a separate line after the label,which isn’t a standard practice. This can be done using some CSS and a Zend Decorator element.

CSS Code:

label.inline {
display: inline;

}
.inlinecheck{
clear: both;
float: left;
width: 25px;
margin-bottom: 0;
}

Zend PHP Code:

$this->addElement('checkbox', 'mycheckbox', array(
'label' => 'My Label',
'name' => 'mycheckbox',
));
$this->getElement('mycheckbox')->addDecorator('Label', array('placement' => 'APPEND'));
$this->getElement('mycheckbox')->addDecorator('HtmlTag', array('tag' => 'dl','class' => 'inlinecheck'));

Rename mycheckbox with the name of your element and set the label accordingly.

PhpStorm sale 50% off

September 12, 2012 9:32 am /

 

JetBrains has their annual sale where they offer PhpStorm for $49. This is a good time to pick up a really good IDE for PHP. I’ve used many different IDE editors for PHP including NuSphere PHPEd, Eclipse, and NetBeans. The standout features for PhpStorm are the speed, cross-platform compatibility (OSX, Windows, etc), and intelligent code completion for classes and methods. It really helps speed up development time when you have a large codebase. Another nice feature with PhpStorm is the built-in Git integration. At 50% the regular price of $99 — its a great deal for $49.

Update 9/20/2012 – Sale ended. They now offer a new $29 academic license option for students.

Zend Framework – Setting global variables in application.ini

August 17, 2012 5:13 pm /

Here are some basic instructions to setting up global variables in Zend Framework using the application.ini file (application/configs/application.ini):

1) Create a service name for your global variable in application.ini. Usually, you group them by the API name. 

For instance, if you have an API called “myapi” and you want to store a global variable myvar = “1234”.  Add the following line to your application.ini

myapi.myvar = 1234

2) In your controller, use the following code to access the global variable:
$myapi = $this->getInvokeArg('bootstrap')->getOption('myapi');
$myvar = $myapi["myvar"];

phpDocumentor – GraphViz package install on Mac OSX

June 26, 2012 10:13 am /

phpDocumentor has a few dependencies in order to work correctly on OSX. If you get the following error message when generating documentation in phpdoc:

Unable to find the `dot` command of the GraphViz package

you will need to install the GraphViz package via homebrew.

If you don’t have homebrew installed on OSX, here is a link to it: http://mxcl.github.com/homebrew/

brew install graphviz

This will quickly install GraphViz on OSX. PhpDocumentor will be able to generate the Class Inheritance Diagrams after GraphViz is installed.
