Webmaster tips & hints

Register a domain name
When creating a website, soon there is the need for an own internet domain name, so the website will be found at www.my-domain.com. This tip shall help where to find information on registering the domain name. more....


Redirect a visitor to other sites
To redirect the visitor to another page or URL, you can use either HTML an Meta tags, Javascript, PHP or htaccess redirection. more....


Waitingtime with PHP
Sometimes you just have to wait - for example to check a script for errors and read the messages, or to let some time after a failure login go by. This works really easy with the command sleep(seconds);


Set as startingpage
The Internet-Explorer browser allows to use a link to change the users starting-page. With this link you can offer your users to easily find you again:

<a href="#" onclick=
"this.style.behavior='url(#default#homepage)';
this.setHomePage('http://www.computerhilfen.com');">
Set this as startingpage!</a>

Add to favourites
Another link lets you add a website directly to the users bookkmark list, when he is surfing with the Interet Explorer:

<a href="javascript:window.external.
AddFavorite('http://www.computerhilfen.de/',
'Computerhilfen.de')">
Zu Favoriten hinzufügen</a>

Use regular expressions with PHP
Using regular expressions with php, webmasters have a great opportunity to grap information out of their sites. more...


Automatically get the image size
It makes your websites being displayed a little faster, when the image size of a picture is given in the sourcecode with the HEIGHT and WIDTH attributes. If the image-size could change later, it is easier to retrieve this information with PHP out of the image:

<?php $file="image.jpg";
$size = getimagesize($file);
echo '<img src="'.$file.'"
width="'.$size[0].'"
height="'.$size[1].'">'; ?>

PHP selfmade-guestbook (german only)
The members of the computerhilfen forum developed a feature-rich PHP guestbook, which is free to use. Discussion and development of the guestbook.


Untitled Document
If you search for terms like "untitled document", you get a large amount of results back. The problem with this is, that the site cannot be found with the normal key phrases: Many webdesign-tools have a predefined "title" tag like "untitled document". You should look for the code between <title> and </title> on your websitet and change it to some text, that fits your site better.


Bad links
The difference between good and bad links is easy: If the visitors sees a link and directly sees where it leads him, the link is good. Our first "bad links" example links the little kittens. Normaly, you should be able to read where the link leeds - unfotunately the mouse-cursors makes it unreadible. In the second example makes the to hard cropped link-image because of the automatical-borders in the Internet Explorer the reading hard.
