PHP: Difference between revisions

Original material by DAJ, but moved to this new page; on a former web-site he used PHP to generate his page, JavaScript to update his page frequently making use of information gathered using AJAX method and the jQuery library of JavaScript code to actually make his script browser independent - see [httphttps://sandaysoftcumulus.com/forumhosiene.co.uk/viewtopic.php?f=14&t=5306 support forum].

One possible advantage of this type of script is that by default the script cannot be seen (unless the developer has added some code ([httphttps://sandaysoftcumulus.com/forumhosiene.co.uk/viewtopic.php?f=14&t=16425 see this forum topic]) allowing a query-string to be added to the url asking for some or all of the PHP source to be shown to the browser). This makes for a more secure script, because it only runs on the web site server. For instance if information is read from a database or in another way involves a password of some kind, all that code can be hidden, the end-user then has no way to modify the script to get information that should not be seen by others. A disadvantage is that it can be more complicated to update information on a page, requiring the whole page to be regenerated. (Consequently, a mix of scripts may be used with updating by AJAX or JSON, added to the PHP that generates the basic page. That is beyond the scope of this article).
