Re: [PHP] wildcard search?
That's because this is a MySQL-specific question and you should be reading the MySQL documentation or asking on the MySQL list. -Rasmus On Mon, 11 Nov 2002, Håkan wrote: I'm trying to make a small and simple search function, but it only works for exact searches, and I can't figure out how to make a wildcard search, if I do it in the php or in the mysql_query, can't really find anything about it and I don't know what to look for on php.net Håkan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] wildcard search?
You'll do it in the database, not PHP. Look into using LIKE in your query... SELECT * FROM yourtable WHERE column LIKE '%searchterm%' The % characters are wildcards that'll match any amount of characters. You can use _ to match a single character. You could also look at FULL-TEXT indexing in MySQL to create a better search feature. ---John Holmes... -Original Message- From: Håkan [mailto:hw2k;barrysworld.com] Sent: Monday, November 11, 2002 4:43 PM To: [EMAIL PROTECTED] Subject: [PHP] wildcard search?

Re: [PHP] Wildcard search
How about:
$a = explode (' ', shell_exec (ls $foldername/*.html));
This should return an array that contains the name of all the *.html
files in the folder $foldername, if any.
Hope this helps.
Cheers,
Marco

Does anyone know if it's possible to do a file search with a wildcard character? I
need to find if there are any HTML files in a certain directory, but
file_exists(htmls/*.html) doesn't seem to work when tested. Neither do similar
applications of readdir(). Is there another way to do this, or do I have to do a
readdir() and read the filename of every file until I find an HTML or until all files
have been read.

-Original Message- From: Mako Shark [mailto:phpman2000;yahoo.com] do I have to do a readdir() and read the filename of every file until I find an HTML or until all files have been read. This is what the shell expression supplied by Marco Tabini actually does; doing it in PHP (readdir(), etc.) eliminates the exec of the shell process and is faster (readdir() is a thin veneer on the readdir system call) and the problem of portability if you want to use this on both Unix and Windows. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Didn't know of shell_exec() until now. It works, though. Thanks!
Is there any reason why it wouldn't work? If I changed servers, say, and there were
some ports blocked and etc. etc., is there a risk that I should know?

Re: [PHP] Wildcard search
Well, as a general rule, it won't work if you're not using a UNIX o/s or
if PHP has been set up with safe mode on, or if you don't have the right
permission to see that folder. That's probably a non-inclusive list, but
there should be ways around each of these problems (depending on the
degree of control you have over the server).

Re: [PHP] Wildcard search
If you're only executing one-liners and get all the results back you're better off using shell_exec(). popen() lets you open a pipe to a command--that way, you can funnel data to it as if you were typing from the keyboard. Permissions would be a problem with readdir() as well.

Re: [PHP] Wildcard search
If you're only executing one-liners and get all the
results back you're
better off using shell_exec(). popen() lets you open
a pipe to a
command--that way, you can funnel data to it as if
you were typing from the keyboard.
That's what I'll do then: use shell_exec().
Permissions would be a problem with readdir() as
well.
So this really shouldn't be a deciding factor then.
Anyway, I've got it working out. I have it returning
an array of filenames if successful. If it's a
successful call, but no files exists (for instance
*.html with no HTML files), then it returns 0. If it
can't read the directory or the dir doesn't exist, it
returns NULL.
Just to make sure, I can do this:
if($files = GetFileListing(htmls\*.html)) {
.
.
.
}
and it will skip it if there either are no HTML files,
oe htmls doesn't exist, right? If I get a 0 or a NULL
return? (I figure, if I need to distinguish between
these two, I can always do a $==0 or $==NULL comparison).
