1) See how difficult it was

3) Add some speed to projects that crunch a lot of data in PHP.

The extension I’ve released adds the following functions:

/**
* Given a multi line input, removes empty lines and whitespace at the ^ and $ of each line.
* Remove duplicate lines by setting the second param to true.
* Naturally case insensitive sort by setting the third param to true.
*
* @param string $string string to trim.
* @param boolean $unique strip duplicate lines [default: false]
* @param boolean $sort sort returned lines [default: false]
*
* @return string
*/
function wadew_multiline_trim($string, $unique = false, $sort = false){}

/**
* Returns an array of strings by casting to string or calling magic __toString()
*
* @param array $elements elements to convert

        return array_intersect($implementedMethods, array('get', 'put', 'post', 'delete', 'head', 'options', 'trace'));
    }
}

If you extend this controller for all your actions, you’ll get automated Allow headers every time someone calls a URL that does not implement their request type.

As I said in my talk, be sure to use an op-code cache so reflection doesn’t become your bottleneck!

Also I should mention, this code lives in my ApiController and not in an action helper or similar due to Zend Framework’s performance hit as a result of using magic methods.

So after a bit of web scouring about how to get Java to trust your site I came across instructions and thought I’d re-post here simplified for anyone who needs to query HTTPS from RESTClient.

These instructions are based on Windows 64-bit and Java being installed into C:\Program Files (x86)\Java. So you may have to change a few paths but the core things are the same.

Navigate to the website in your browser, click the SSL icon in the address bar and click Certificate Information or Details etc.

In the window that pops up, go to the Details tab then click the “Copy to File” button. Click Next until you get to the request for a Filename. Click Browse and navigate to “C:\Program Files (x86)\Java\jre6\lib\security”. Enter the filename to save the certificate as (I suggest the domain name with .cer ending). Finally click Next and Finish.

Now open up a command prompt (if you’ve got Windows security then be sure to run as administrator [right click the shortcut to the command prompt and the option is there]) and enter the following:

cd "C:\Program Files (x86)\Java\jre6"
bin\keytool.exe -noprompt -import -keystore lib\security\cacerts
     -alias (put_domain_name_here)
     -file lib\security\(name_of_certificate_you_saved_above).cer

The second command should all be on one line. You’ll get asked for a password, if you’ve never touched any Java passwords on your machine before, it’ll probably be the certificate store default which is either changeit or changeme.

That’s it! You should now be able to query your service using HTTPS without any errors.

Then the talk has become abstract, each point is prefixed with an odd statement such as “Only elephants remember everything” and “Not all matches are made in heaven” – people are getting it, but everything needs explaining before they get it!

One very good point I have seen ignored many times is “try not to be greedy.” For example /<(.+)>/ in the string <a href=”">fdsfsd</a> will match the entire thing. To make it ungreedy, either use /<(.+?)>/ or /<([^>]+)/ . Greedy matches can be 20+ times slower.
