I've recently been interfacing with a SOAP API on a .NET server and also creating an API in PHP, and both require sending a specific SOAP header for authentication. This post shows how to send a SOAP header using the PHP SOAP client which is built into PHP.
Sending an authentication header with PHP SOAP
In the case of the SOAP server I have been developing, the server requires a header to be sent which contains the API key. The header name is APIKey and the value the key itself. In the example below the namespace used for the API call is "ExampleNamespace".

I have a number of batch processes that run using PHP as the command interpreter, and discovered after making a change to one of them the other day that the variables available to PHP in the $_SERVER superglobal are different depending on whether it's run via an SSH session or cron. This post shows the difference on Debian 6. The values available are probably the same on other distros.
$_SERVER using the CLI via SSH
Using the PHP command line interpeter (CLI) the following was displayed when running print_r($_SERVER), showing which variables are available:

If you are connecting to a remote server from the Mac OS X terminal and get the message "Error opening terminal: xterm-color" when doing certain operations on the remote server, then you either change your terminal's declaration setting or add a TERM declaration to the bash profile on the server at the other end to prevent the error message from happening. There may be other ways to solve it at the server end but this post shows a quick and easy fix.

Sometimes we need to restore only some tables from a full backup maybe because your data loss affect a small number of your tables. In this particular scenario is faster to recover single tables than a full backup. This is easy with MyISAM but if your tables are InnoDB the process is a little bit different story.

I spent last week at linux.conf.au in Ballarat, Victoria (that’s the Victoria in Australia, not wherever else there may be one) which is only a pleasant two hour drive from my home town of Melbourne (Australia, not Florida). I sent an email internally to our experts detailing bits of the conference that may interest them – and I thought that it may also interest our wider readers who are interested in all levels of the software stack.
