[PHP] Finding out if a table exists
Is there a way of finding if a table exists with only
one command in MySQL? I've looked through the MySQL
functions, and the closest I've gotten to what I need
is mysql_list_tables or mysql_tablename (I'll have to
check into these a little more), but I was hopefully
looking for something that returns a boolean value,
and to be able to use it like:
if(mysql_table_exists(tablename)) {
...
}
Any ideas, short of creating my own function?

Re: [PHP] strstr-pls help
Your problem is with this line: $adam=fread($ip,filesize($adam)); Remember that $adam is not a file pointer, but text read from a file. The file pointer is $ip, so the line should read: $adam=fread($ip,filesize($ip)); (and should probably be contained within an if statement for error handling). __ Do you Yahoo!? Yahoo!

Re: [PHP] strstr-pls help
but it doesnt work, You sure? It should be that you were trying to get the sizeof() $adam, which was thus far 0 bytes. So, of course, it would return 0 bytes to $adam, and your strstr() of looking for the IP address wouldn't work, since $adam would contain nothing. Try print()ing $adam to see what's actually coming out, then fiddling with your block1 part. __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

[PHP] $_FILES associative array
I'm trying to find some documentation on the $_FILES array, but on PHP, it's a little confusing. I read the documentation and the comment from rep_spam@..., but that wasn't too clear to me either. I'm aware that when uploading a file named $uploadedfile, the size, name, etc. get stored in variables called $uploadedfile_size, _name, But when using the $_FILES array, does everything then get stored in $_FILES[uploadedfile], $_FILES[uploadedfile_size], etc...? __ Do you Yahoo!?

[PHP] Multidimensional array
(Thanks to all who've replied about the streaming audio. Haven't had a chance to respond or anything yet.) Here is a problem I'm having similar to somethnig someone just posted, but not quite the same. I'm not too experienced with the intricacies and complications of arrays, but I have a bunch of fields like this for a magazine organizer (best way to put it, I guess): $issuenumber[] $issueheadline[] $issuewriters[] $issuemonth[] $issueyear[] $issuedescription[] among other fields. I would like to store this all in one multidimensional array, like $issue-number[] $issue-headline[] etc. What is the syntax? I'm bumbling around right now. Also, if I sort() the array by number, would the rest of the fields be properly sorted? I assume so, but don't want to find out the hard way that it doesn't. __ Do you Yahoo!? Yahoo!

[PHP] Multidimensional arrays (more and more...)
Wow. This goes way beyond simply printing multidimensional arrays.

I read that PHP is screwy when counting and sorting multidimensional arrays, but they *have* to have come up with a method, right? __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

[PHP] Re: Multidimensional arrays (more and more...)
Thanks to Paul and Marek for some ksort() advice. I'll try that out as soon as I can count() these buggers. A little more info on my count()ing. I have $issue[0][number] to $issue[x][number] just like any other multidimensional array (we'll call them m-arrays for simplicity). If I try to count($issue), I'll get all instances of my array (instances?) mltipled by the number of elements (don't know if this includes NULLs or not, don't have NULLs). If I try to count($issue[]), it'll give me the number of elements (8), which is also not correct. If I try to count($issue[][number]) it says I can't pass that to the count() function (which is logical). But it leaves me with no way of count()ing my instances. My problem is I need to loop through these. So I can't just assume that the count is count($issue[]) divided by 8, because that won't work in a for loop. I suppose I could just iterate through my for loop in jumps of 8, but that seems really hacky and unintuitive to whomever has to figure out my code when I'm gone. If there's a kcount(), I'm all for it. :) __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

Re: [PHP] Multidimensional arrays (more and more...)
if [$number] is unique, use it as the key: Yeah, I'd thought of that except there's no guarantee that it will be unique. Plus, it makes it harder to go through with a simple loop because $number really isn't guaranteed to be numeric (okay, so I have to change the name). Plus, it may not even start from 0, For instance, it doesn't have to be from 1-10, it could be from 75-85. __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

[PHP] Order of arrays
I don't think a simple sort() will do this. Is there a way I can sort these following array values so that all will be in numerical order, and then alphabetical after that? I need Dirfiles/97 Dirfiles/98 Dirfiles/99 Dirfiles/100 Dirfiles/101 Dirfiles/102 Dirfiles/ABG1 Dirfiles/ABG2 in that order. They could originally be in any seemingly random order, but when I'm done with it, I need them in that order. Is there a way to do it? A simple string sort() won't work since 9 comes after 1 and it'll order it like 'Dirfiles/100,101,102,97,98,99,ABG1,ABG2'. Any ideas? For some reason, natsort() won't work. __ Do you Yahoo!? Yahoo!

[PHP] Still having ereg migranes
Sorry to repost this, but I haven't found a solution and it's still nagging me. Maybe some of you can come up with something I can't. Here was my original post: I've made myself an INPUT TYPE=HIDDEN tag that contains in the value attribute a list of comma-delimited numbers. I need to find if a certain number is in these tags (and each file contains one tag). I need an ereg statement that will let me search these lines to see if a number exists, obviously in the beginning or the end or the middle or if it's the only number in the list. So, say I need #1, I need to grep each file to find if 1 is in its INPUT TYPE=HIDDEN list. Here's what I mean (searching for number 1): INPUT TYPE = HIDDEN NAME = numbers VALUE = 1,2,3,4,5 //beginning INPUT TYPE = HIDDEN NAME = numbers VALUE = 0,1,2,3,4,5 //middle INPUT TYPE = HIDDEN NAME = numbers VALUE = 5,4,3,2,1 //end INPUT TYPE = HIDDEN NAME = numbers VALUE = 1 //only I can't grab all the tags and search for it in PHP (there would be too many tags to parse through and I'd rather let the OS handle that). I need to do this at the operating system level. Does anybody yet have a solution? I *know* it's possible, but I can't get it and I've been working on it for days now.

RE: [PHP] Still having ereg migranes
first way:
if(ereg('([^0-9]|^)'.$your_number.'([^0-9]|$)',$_REQUEST['numbers'])
) second way:
$numbers=explode(',',$_REQUEST['numbers']);
if(in_array($your_number,$numbers))
Not sure I get this but, again, I can't use $_REQUEST
or explode or in_array at this point. The entire
process needs to happen in the shell_exec() command,
because I'd much rather have that handle the whole
shebang than PHP.

this is probably not at all what you want, but i wrote it just in case. . . . if 1 is in the string it will return either middle, left, right or only.. if it is not it will return false.

[PHP] Re: GD 1.5
If the OP was concerned about such issues then he/she should not be using GIF at all! This is leading me to believe that I can't use GIFs because of these issues. Is this true? I know now that Unisys (Unisys?) made a fuss about some compression or whatever, but someone told me it was still okay to use old GDs (am I naive? maybe). Is it now considered piracy to use GIFs at all? Does this mean I have to switch over to JPGs, even those images that compress better with GIFs? I just assumed we were still permitted, what with Jasc and everybody still allowing it in their products. Is JPEG (or PNG) the way to go?

Re: [PHP] Wildcard search
Well, as a general rule, it won't work if you're not using a UNIX o/s orif PHP has been set up with safe mode on, or if you don't have the rightpermission to see that folder. That's probably a non-inclusive list, butthere should be ways around each of these problems (depending on thedegree of control you have over the server). These are fine. I'm not going to use Windows for a server. Won't the same problem in relation to directory permissions stop me even if I just did a simple readdir()? The only one I'm too worried about is the safe mode thing. It works for now, though. The next server I'm moving to will hopefully be my own, so I'll have complete control. And, if not, all of my shell_execs() are in a function, so I only have to change it in one place. But is it less troublesome to use a popen instead of shell_exec? What are the differences, aside from that popen remains open past one command? I'm using both here and there in my site, and am wondering if one is better than the other if all my shell commands are single-line commands. __ Do you Yahoo!?

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).
