How to Resize Image Dynamically in PHP

There is an extremely useful PHP library called timthumb which comes very handy. It’s just a simple PHP script that you need to download and put in some folder under your website. And then simply call it with appropriate arguments.

Download timthumb.php and put under any folder.

Upload this script timthumb.php though FTP to your web hosting. Put it under a directory /script.

Just call timthumb.php with appropriate arguments, For example:

<img src="/script/timthumb.php?src=/some/path/myimage.png&w=100&h=80"     alt="resized image" /> And that’s all!!

One thing worth noting here is that this library will create a folder cache in the directory where timthumb.php script resides. This folder will cache the resized image for better performance.

You can refer following table for different parameters and its meaning.

	Parameter	Values	Meaning
src	source	url to image	Tells TimThumb which image to resize
w	width	the width to resize to	Remove the width to scale proportionally (will then need the height)
h	height	the height to resize to	Remove the height to scale proportionally (will then need the width)
q	quality	0 – 100	Compression quality. The higher the number the nicer the image will look. I wouldn’t recommend going any higher than about 95 else the image will get too large
a	alignment	c, t, l, r, b, tl, tr, bl, br	Crop alignment. c = center, t = top, b = bottom, r = right, l = left. The positions can be joined to create diagonal positions
zc	zoom / crop	0, 1, 2, 3	Change the cropping and scaling settings
f	filters	too many to mention	Let’s you apply image filters to change the resized picture. For instance you can change brightness/ contrast or even blur the image
s	sharpen		Apply a sharpen filter to the image, makes scaled down images look a little crisper
cc	canvas colour	hexadecimal colour value (#ffffff)	Change background colour. Most used when changing the zoom and crop settings, which in turn can add borders to the image.
ct	canvas transparency	true (1)	Use transparency and ignore background colour

Hope this is useful for you :)

Redirecting www to non-www with .htaccess

Redirecting www to non-www

If you want to do the opposite, the code is very similar:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^my-domain\.com$ [NC]
RewriteRule ^(.*)$ http://my-domain.com/$1 [R=301,L]

Redirect non-www url to www with .htaccess

If you want to redirect all non-www requests to your site to the www version, all you need to do is add the following code to your .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

How to create Yii Web application and new info about Yii Framework

The latest version of Yii 2 is 2.0.0 beta, released on April 13, 2014.
Yii 2.0 is not ready for production use yet. It is currently under heavy development.

How to hide index.php from url in yii

URL rewriting in Yii to hide index.php

To hide the index.php from url you have to make the changes in config/main.php  as shown below,

‘urlManager’=>array(
                              ‘urlFormat’=>’path’,
                              ‘showScriptName’=>false, //this option will be hide the index.php from url
                              ‘rules’=>array(
                                                ‘<controller:\w+>/<id:\d+>’=>’<controller>/view’,
                                               ‘<controller:\w+>/<action:\w+>/<id:\d+>’=>’<controller>/<action>’,
                                              ‘<controller:\w+>/<action:\w+>’=>’<controller>/<action>’,
                                             ),
), 

and create new .htaccess file in the same directory as my index.php file shown as below,

RewriteEngine  On
RewriteBase  /
RewriteCond   %{REQUEST_FILENAME} !-f
RewriteCond   %{REQUEST_FILENAME} !-d
RewriteRule    ^(.*)\?*$ index.php/$1 [L,QSA]

You can change the ”RewriteBase /’  as per project location like if project is located in ‘abc/′ of webroot.
then it change like as    RewriteBase  /abc

That will make sure your auto-generated links (CHtml::link or zii.widgets.CMenu) do not have index.php in them. This will not work without the .htaccess file. The reason is that the .htaccess file rewrites the url to point to index.php/$1 so that Yii actually gets the request properly. You will not see the index.php in the url at any time though.
