| | PHP is server-side. It can ONLY work with the directory structure on the server. This sounds like something for a client-side language like javascript, but I imagine there are security restrictions in place in most/all browsers to prevent or hinder the ability to recurse through the user's harddrive. Can't say … |
| | PHP is a server-side language. It could care less what browser you are using. I'm going to take a total shot in the dark and say if this works in FF and not in IE then it has something to do with how the data is being passed from your … |

| | There is no comparison between OOP and structural php programming in my mind. OOP is composed of most of the concepts and functionality that is "structural" programming.

| | Has anyone else ever taken the XML/XSL approach? I found generating XML representations of my output and using XSL style sheets to do the transformations with the php XSL extension to quite powerful and surprisingly fast. It also truly separates your php from your template while also being a w3 … |
| | To my understanding, this is exactly how MyISAM and InnoDB both work with slight differences. MyISAM locks the entire table while InnoDB locks a row during an insert/update. It appears you can manually lock and unlock a table for a query though if necessary. [url]http://dev.mysql.com/doc/refman/5.0/en/lock-tables.html[/url] Some info on table locking … |
| | Depending on the complexity of the directory structure you're trying to navigate i'd recommend looking at the Standard PHP Library (SPL) specifically at [URL="http://php.net/manual/en/class.directoryiterator.php"]DirectoryIterator[/URL] and [URL="http://www.php.net/manual/en/class.recursivedirectoryiterator.php"]RecursiveDirectoryIterator[/URL] They're going to greatly simplify navigating very complex hierarchies.

 | You could also use a PHP 5 DirectoryIterator from the SPL library. [CODE=php] $iterator = new DirectoryIterator('/path/to/directory/'); foreach($iterator as $fileinfo){ if( !$fileinfo->isDot() && $fileinfo->isFile() ){ echo $fileinfo->getPathname(); } } [/CODE] DirectoryIterators implement the SplFileInfo class ([url]http://www.php.net/manual/en/class.splfileinfo.php[/url]) so anything available there is also immediately available in $fileinfo From my quick tests … |
