How to debug a PHP script

It could be useful sometimes to know what variables are defined at particular point of PHP script in order to have a better understanding of the code you are debugging. In contrast with C++, PHP has a magic function get_defined_vars ( void ) that  returns an array of all defined variables with their values so we can output all variable names with the following line of code:

print_r(array_keys(get_defined_vars()));

How to pass a Dictionary<Key, Value> from C# to PHP

I believe that the simplest way to pass complex data from C# to PHP is through WCF service. See my previous post How to implement WCF service in PHP for more details.

Let assume we have a WCF service contract that has the following method with some nested dictionary as a parameter:

[ServiceContract]
public interface IStore
{
    [OperationContract]
    void UpdateRows(Dictionary<int, Dictionary<string, object>> rows);
}

Below I provided the sample implementation of UpdateRows in PHP that iterates through nested dictionaries (first level called ‘rows’ and second level called ‘properties’):

How to implement WCF service in PHP

Today I implemented my first PHP Web Service and successfully used it by C# client or, more precisely, I created WCF service contract in C# and implemented it in PHP.  A new option “singlewsdl” in WCF 4.5  helped me a lot. Using this option I generated the service description as a single WSDL-file without additional XSD-files containing the data contracts of the service. Then I uploaded this WSDL-file on my Web Server and written PHP code for all the methods of the service.

Integrating C# and PHP using XML-RPC and WCF

While investigating how to make C# and PHP interact with each other I run into an interesting extension of WCF Service Model for working over XML-RPC protocol. I played a bit with this extension and after fixing some bug in its source code I made it work with my little custom XML-RPC server implemented as Joomla XML-RPC plugin.

How to make PHP Web Service with NuSoap

While investigating how to create a Web Service in PHP I run into NuSoap library, that can generate WSDL based on some matadata describing Web Service method signatures and the data structures. I downloaded NuSoap library and found some trivial sample that started working after adding the highlighted line of code:

How I configured sendmail for PHP on Ubuntu Server 12.04

Preventing sendmail from been very slow

The first thing that I did after installing sendmail with

aptitude install sendmail

is I put “gate.localhost” (gate is my server name) to /etc/hosts so it looks like this:

127.0.0.1       localhost.localdomain localhost
127.0.1.1       gate.localhost gate

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

With default /etc/hosts containing only “gate” and “localhostsendmail hangs up for a while and writes to /var/log/mail.log the following message:

My unqualified host name (gate) unknown; sleeping for retry.

How to setup Eclipse with PHP Developer Tools and FTP support

Using Eclipse as PHP IDE

After working a little with phpDesigner, I felt that, probably, I need more complex PHP IDE. Because I previously worked with Java applications using Eclipse I decided to add PHP support to my existing Eclipse for Java EE (Helios) installation previously downloaded from http://www.eclipse.org/downloads/. I navigated to Help->Install New Software in Eclipse, selected “–All Available Sites—“, searched for “php” and got the same plugin in three different categories:

Adding footers and meta tags to WordPress posts

Adding post footer

There are a lot of plugins for adding footers to WordPress posts and one of them is so called “Add Post URL” plugin written by some Chinese guys. From my perspective, its benefits includes macros support and ability to decide whether or not to display the footer for each post individually. It worked fine for me and I even improved it a little bit. The following code snippet shows how I added “post_id” macro:

$footer_text = $posturl_options['footer_text'];
$footer_text = trim($footer_text);
if (!empty($footer_text))
{
    //remove_filter( 'the_content', 'wpautop' );
    
    $post_id = get_the_ID();
    
    $footer_text = str_replace("%post_id%", $post_id, $footer_text);
    $footer_text = str_replace("%site_url%", site_url('/'), $footer_text);
    $footer_text = str_replace("%site_name%", get_bloginfo('sitename'), $footer_text);
    $footer_text = str_replace("%post_url%", get_permalink(), $footer_text);
    $footer_text = str_replace("%post_title%", the_title('', '', false), $footer_text);
    $footer_text = stripslashes($footer_text);
    $text .= $footer_text;
}

Getting WordPress multisite work with Windows Live Writer

Windows Live Writer is configured for working with WordPress multi-site the same way as with normal single-site WordPress installation, but WordPress works a bit differently in multi-site and single-site configurations. The difference consists in a few lines of code in wp-includes/class-wp-xmlrpc-server.php:

function wp_getUsersBlogs( $args ) {
    global $current_site;
    // If this isn't on WPMU then just use blogger_getUsersBlogs
    if ( !is_multisite() ) {
        array_unshift( $args, 1 );
        return $this->blogger_getUsersBlogs( $args );
    }

    //single-site verion...
}
