Compressing Stylesheets with PHP

Posted by bekco in PHP, Programming Languages, Software Engineering, Web Design on June 21, 2011

If you wonder what else you can do to compress your files, I found a PHP code of which is written by a German coder that is shared on another blog. Basicaly it removes spaces and back slashes to minify the included files and compress them using ob_gzhandler.

  header('Content-type: text/css');
  ob_start("compress");
  function compress($buffer) {
    /* remove comments */
    $buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $buffer);
    /* remove tabs, spaces, newlines, etc. */
    $buffer = str_replace(array("\r\n", "\r", "\n", "\t", '  ', '    ', '    '), '', $buffer);
    return $buffer;
  }

  /* your css files */
  include('master.css');
  include('typography.css');
  include('grid.css');
  include('print.css');
  include('handheld.css');

  ob_end_flush();

Compressing Web Site Contents, Scripts and Stylesheets

Posted by bekco in Javascript, PHP, Programming Languages, Software Engineering, Web Design on June 21, 2011

Today I wonder how I could minify my javascript files and do a server side compression to minimize the cost of loading web site requred javasript and stylesheet files. Where to begin… I’ll start from Apache Server configuration information for server side compression and finish with YUI Compressor that helps you to minify your script files as you should have seen those files ending with “your_script_file.min.js”. If you are using Apache Server, you might have Deflate Module installed with your Apache installation. What you need to load this module while your your server starts is to configure your apache configuration file.

LoadModule deflate_module modules/mod_deflate.so

And if you have access to the httpd.conf then you can add following lines to it.

<Location />
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/x-js text/css
</Location>

If not; you should specify the initialization line into your htaccess file.

<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/css text/plain text/javascript text/xml application/xhtml+xml application/x-httpd-php
</IfModule>

You might have problems to compress javascript files which has different mime types. Then, you can use followig configuration.

AddOutputFilterByType DEFLATE application/x-javascript

That will do. Now, I will introduce YUI Compressor. YUI Compressor is one of Yahoo developer team product that you can download from here. If you have dowloaded the YUI Compressor built from the site that I shared above, what you should do to compress your file is:

java -jar yuicompressor-x.y.z.jar myfile.js -o myfile-min.js --charset utf-8

Where, x, y and z are the version number of the YUI Compressor download. Also you can find more information about YUI Compressor at http://developer.yahoo.com/yui/compressor/#work

Thank you for reading, I hope this will help some of you guys.

CakePHP : Translate Behaviour : Fixing Nested Translation Problem

Posted by bekco in CakePHP, Data Querying, Frameworks, PHP, Programming Languages, Software Engineering on June 12, 2011

If you ever tried to use Translation Behaviour of CakePHP you should realize that Translate Behavior does not support nested translations for the model relations. I’ve found one article that shows how to fix a similar translation problem on related models at http://groups.google.com/group/cake-php/browse_thread/thread/9b7e60900269643b%29.

Unfortunately it was not a complete solution that you can implement easily but it gave me a good approach to help the model to request nested queries to make Translate Behaviour work.

I need to warn you that this solution is not a really good one but until CakePHP team fix this issue on one of the future releases of CakePHP this would help you a lot.

Here is the code:

class AppModel extends Model {

    var $_findMethods = array('all' => true, 'first' => true, 'count' => true,
		'neighbors' => true, 'list' => true, 'threaded' => true, 'translated' => true);

    function _findTranslated($state, $query, $results = array()) {
        if ($state == 'before') {
            return array_merge($query, array(
                //'fields' => array('id', 'name'),
                //'recursive' => -1
            ));
        } elseif ($state == 'after') {
            if (empty($results)) {
                return $results;
            }

            // get the model's belongs to relation model names
            $belongsTo = Set::extract($this->belongsTo, '/@*');

            if(!empty($belongsTo) && isset($belongsTo[0]) && is_array($belongsTo[0]))
                $belongsTo = $belongsTo[0];

            if(!empty($belongsTo))
                foreach($results as &$result)
                {
                    foreach($belongsTo as $modelName)
                    {
                        if(isset($result[$modelName]) &&
                            isset($result[$modelName]['id']) &&
                            !empty($result[$modelName]['id']))
                        {

                            $data = $this->$modelName->find('first', array(
                                'conditions' => array(
                                    $modelName.'.id' => $result[$modelName]['id']
                                ),
                                'recursive' => -1
                            ));

                            if(!empty($data))
                                $result[$modelName] = $data[$modelName];
                        }
                    }
                }

            return $results;
        }
    }
}

What you need to do is just implement the _findTranslated method on your model or on AppModel for general usage with the $_findMethods private variable and instead of using regular find methods for example:

$this->Post->find('all');

You should use:

$this->Post->find('translated');

And the result will look as the same above but with translated inner relations.

Not: I have not implement all types of the relations yet but if you find hard to add such relations let me know, I’ll do my best.

I hope this could help you. Please leave me some responses to make sure is helpful.

Thank you for reading this article.
