Using wildcards with PHP file functions
 

I am assuming that you cannot use wildcards # or * with the PHP unlink function. I need a way to delete the pictures off of our web page when we delete a product. All the products pictures are located in the same directory and begin with p_'product number'.... I tried the command unlink(p_'product number'*) but the files weren't deleted. I checked the php manual and they don't mention wildcards. I thougt I could write a function to scan the directory and produce a list of files to unlink but this still would reqire the use of a wildcard.

Any ideas?

I dont know if your pictures are named or .
Assuming the second:
you can concat p_ to product number using dot (.) operator. For example
where pNum contains the product number.

If this doesn't help, take a look at ereg() manual.

Wildcards are interpreted by the shell, so there are two easy solutions:
Don't use them. PHP-Functions don't interprete them.
use opendir & co to scan thru a directory and use unlink

or

do it the nice way:
system("rm whatever");

with exec && system you can execute shell commands :-)
