How To Display Certain Amount Of Letters Numbers From Data Get String PHP

the PHP substr() function is useful when creating long title links.

For example, i want to create a link with the following text:

This is a very long text link I am creating to show this helpful function in php because i think that this will help others make their websites better and look professional at the same time

ok, as you can see from the above link, its way to long. its probably has like 300 characters, but lets say i want to keep this type of link to a maximum of 50 charaters, so i will ONLY display the first 50 characters of the long link to make it short. so the new link should look like this:

This is a very long text link I am creating to ...

so how do you do this? PHP offer alot of usefule functions, the substr() will return only a specified number of characters from a string. so you can learn how this function works, i've created a php file you can upload to your site to see it in action:

NOTE: for this function to work, you will need to have PHP, if you don't have PHP on your webstie, we recommend our friends at www.webune.com for PHP hosting. check them out.

Copy and paste the following into your text editor like notepad:

Code:

<?
$link='This is a very long text link I am creating to show this helpful function in php because i think that this will help others make their websites better and look professional at the same time';
?>
This is the value of $link: 
<a href="http://www.wallpaperama.com"><?php echo $link; ?></a>
 
Now this is the link with the substr() function:
<a href="http://www.wallpaperama.com"><?php echo substr($link, 0, 37); ?> ...</a>
This is the code i used to display characters from 0 to 35 only: <?php echo substr($link, 0, 37); ?>
