PHP: Difference between revisions

TheOne possible advantage of this type of script is that by default the script cannot be seen (unless the developer has added some code ([http://sandaysoft.com/forum/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).
