    FUNCTION TO SHOW READ MORE LINK IN PHP.
    DONT FORGET TO CLICK THANKS. ;) :p
    Have you ever came across a situation where you need to truncate the large text and show the "read more.." link to redirect user to read the full post ?
    I know you might be searching for a function to show read more link in php.

    Here is a simple function which can be used to show the "Read more.." links dynamically.

    PHP Code:
    <?php  
    //function to truncate text and show read more link  
    function truncate($mytext,$link,$var,$id) {  
    //Number of characters to show  
    $chars 25;  
    $mytext substr($mytext,0,$chars);  
    $mytext substr($mytext,0,strrpos($mytext,' '));  
    $mytext $mytext." <a href='$link?$var=$id'>read more...</a>";  
    return 
    $mytext;  
    }  
    ?>

    The above function can be used anywhere to show read more links with dynamic mysql queries.

    How to use this function ???
    Here is a simple example to do this
    First you will need to create the connection with the database.
    Connection settings are stored in "connect.php" file

    PHP Code:
    <?php  
    include "connect.php";  
    $sql "SELECT * FROM articles";  
    $result mysql_query($sql);  
    while(
    $row mysql_fetch_array($result))  
    {  
    echo 
    "\n";  
    echo 
    truncate($row['article_text'],"article.php","article_id",$row['article_id']);  
    }  
      
    //function to truncate text and show read more link  
    function truncate($mytext,$link,$var,$id) {  
    //Number of characters to show  
    $chars 25;  
    $mytext substr($mytext,0,$chars);  
    $mytext substr($mytext,0,strrpos($mytext,' '));  
    $mytext $mytext." <a href='$link?$var=$id'>read more...</a>";  
    return 
    $mytext;  
    }  
    ?>
    This will output your article text with proper linking to original post with read more link.
    Even you can customize the truncate function for more security check and customizing your display.

      Wat do you mean by that?
      Silently dropping by an useless piece of code.

        Thanks for that tkreturns!

        I just recently had a need for something like that and ended up using JavaScript instead.

        No parenthesis are needed.
