Re: code quest

A good point, but in this application there WILL be AT LEAST 1 legitimate directory at all times, or else the script would not be used, so this ought not be a problem. My problem is that I understand the basic functions to implement, but have not yet aquired sufficient command of php to implement the required multi step algorithm. Jim Lucas wrote:

Hello all, my name is Kirk Bailey, and I am new to php, so please be forbearing. I code in python, and am trying to learn this language as our new client runs a web business based in it. I need a routine that will return a list of every directory immediately under the current directory- but nothing else, just a list of directories, 1 level deep, NO FILES, no listing of current dir or prior dir either. Now in python, I would use os.walk, and use the list of dirs and throw the other 2 lists away, but this ain't Kansas anymore. Does php even DO lists? Um, a list is a 1 dimenional array, if have a list ALIST and you plug in 3, you get back the contents of cell 3 in the list, whaqtever that content is. so if cell 3 in a 6 celled list was "Ruby" then ALIST[3] would return the string "ruby". It's easy to iterate lists. For instance: print '<ul>' for dir in ALIST:

       print '<li><a href=\"/dir>",dir,'</a>

print '</ul> This would let me produce an ordered list of directories, each a link to that directory. This way, when a client installs a new product, the home page area listing products offered automatically updates. Further embellishment would let me replace the dir name with a BRIEF description from a descriptor file read from that dir. Now how to do this in php?

This should do. The only problem that I foresee would be an empty "<ul></ul>" if you have no directories returned by glob(). print('<ul>'); foreach ( glob('./*', GLOB_ONLYDIR) AS $dir ) print('<li><a href=\"'.$dir.'\">'.$dir.'</a></li>'); print('</ul>'); Jim Lucas
