Design question

I have written a generic table browser script in PHP called browse.php. It displays the first 10 records of a database table in an HTML table. It also displays these HTML links: print '<a href="' . $PHP_SELF . '?action=first">Display the first 10 records</a>'; print '<a href="' . $PHP_SELF . '?action=prev">Display the previous 10 records</a>'; print '<a href="' . $PHP_SELF . '?action=next">Display the next 10 records</a>'; print '<a href="' . $PHP_SELF . '?action=last">Display the last 10 records</a>'; Browse.php examines the value of the $action variable and displays the appropriate database table records. Another possibility is to create symbolic links to browse.php called browseFirst.php, browsePrev.php, browseNext.php, and browseLast.php. Using this method, the HTML links would look something like this: print '<a href="browseFirst.php">Display the first 10 records</a>'; print '<a href="browsePrev.php">Display the previous 10 records</a>'; print '<a href="browseNext.php">Display the next 10 records</a>'; print '<a href="browseLast.php">Display the last 10 records</a>'; Browse.php can then examine the value of $PHP_SELF and display the appropriate database table records. Can anyone please comment on the advantages and/or disadvantages of each method, especially security-related issues? Thanks - Jim
