PHP: Help with File Listing

Posted: Thu May 30, 2002 6:47 pm (21 years, 10 months ago)

I have a file named:

msds_Calcium_6%.pdf

in a directory on my server. I want to be able to produce a directory listing where it only lists files that are of type "msds", and named "Calcium 6%". There could be additional files under the "Calcium 6%" product name (e.g. Calcium 6% Advantage) that I would also like the script to show on the web page.

My idea is to have PHP check a directory first for any files listed as "msds", then check to see if they also contain the characters, "Calcium 6%".

Is there a PHP function that looks for a capital letter then checks all the characters after that to a specified string length? This way I could look through the file name until it reaches the first capital letter, check the characters after that, and see if it is a match. If it is a match, then it would print all the files that match the parameter specified.

Thanks for any help,
Ryan

Here is some code I have used in the past, it should get you pretty close.

//Get listing
$handle=opendir("directory");
while($file=readdir($handle)){
$retVal[count($retVal)]=$file;
}

//Clean up and sort
closedir($handle);
sort($retVal);

// Build List
for($i=0; $i<=count($retVal); $i++){
// Check for blank entries
if ((!ereg("[.]",$retVal[$i])) && (!ereg("[ ]",$retVal[$i])) && $retVal[$i]!="") {
if( <insert criteria here>){
<do something with entry>
}
}
}

Good Luck,

Scott
