RE: [PHP] Passing variable to the next page
Here is scenario that I am working on but have a problem. I have 10 thumbnail images on the page with information for them created from database. (I am pulling more info about that image from database, but on this page I only display Name of Image and Author of image, the rest of the info is stored in variables.) I want my users to click on the thumbnail. When they do I want a new window to open and I want information for that particular image that they clicked (along with other info that stored in variables for the same image) to be passed to that new opened page. How can I pass information about that particular image to the new page? Any ideas? Speaking personally, I'd only extract the data you actually need to display - it will lower your overheads (even if just a little) and you won't be in a situation where you have to keep data around on the off-chance that they click the thumbnail for more info. Then if they do click the thumbnail get the data you need from the database. In this scenario about the only thing you'd need to pass your new page would be the ID number from the database - then just do a query for what you need on the new page. The more images you're dealing with, and the more information you extract per image, the more effective this will be at saving you overheads.

RE: [PHP] [PLEASE HELP] Passing variable to new page.
echo script language=\JavaScript\;
echo function pop1() {;
echo window.open(\info.php?prod_id=$result[0]\); };
echo /script;
I am calling this function in the following manner: echoimg
onclick=\pop1();\;
OK, I tend not to put javascript inside php echo statements as it
confuses things - which variables belong to which language. Second, as
it stands, if I understand you correctly, it won't matter which image is
clicked on, you'll always get the same prod_id. That's a logic problem.
?
$myid = $_GET['prod_id'];
echo Product ID: $myidbr;
?
You don't seem to be doing anything much on this yet - except trying to
display text.
Anyway, if you're serious about solving this why not start simpler and
work up. Create yourself some html with the javascript in it to call
your new php page. This way you _know_ what is being passed to your
popup. If this doesn't work then you need to fix your javascript. If
it does work you can start putting your php back into the first one and
see where it stops working - this will likely be what you need to fix.
In future please reply to the group rather than to me personally - and
no, I'm not going to write your code for you.

RE: [PHP] Thumbnail pages - alot of them
I have a mysql database table of about 7000 images (they are not actually in the db, just references), as yet uncategorized. I need to put them online and allow my client to browse 12-18 thumbnails per page. what would be the most efficient method to code that with PHP? any help is appreciated! Query your database to with an appropriate 'ORDER BY' and use 'LIMIT' to get the number you want per page. Display them to a page from within a 'while' loop. Process as you require. Include page navigation to do the next set. What have you tried? Are you having trouble with something specific? If you're not sure what to do then perhaps downloading something that will do it already will work - try www.hotscripts.com or perhaps sourceforge.net or freshmeat.net as good places to start - or even just do a search on google - I suspect searching for 'mysql php image browser' would get you close.

RE: [PHP] convertion from string to time substracting
I got a mysql database, where two of the fields of a table record times as CHAR(8) in the format hh:mm:ss This is one of those situations where having your database using the most appropriate field types would help. When you've got it as CHAR there's little you can do in the way of comparisons in sql. It's probably as good a time as any to create a new column of type 'TIME' and then create yourself a short php script to read in all your char-based times and write them back to the database as time-type times. Once you've done this you can use native MySQL time and date calculations to do all the hard work for you. I want to take this two times and get the difference between them in seconds, for example 12:01:30 - 12:00:00 = 90 I looked up at the doc in the php.net website and couldn't get on how to do this... should I use the strtotime function? If you have some particular reason why you can't convert your columns to time then you'll need to do some work on converting time formats in php instead - this will most likely end up being more processor intensive for any significant iterations of the calculations involved. anyone has donde something like this, or knows what functions could help me to do this? Mostly just using the right field types in sql to start with and then using the wealth of functions available to you.

RE: [PHP] majordomo in php?
Anyone knows of a majordomo type mailing list made with php Why would you want to do that? If you need mailing list software you'd be infinitely better off using one that already exists - if you need features that it doesn't support (eg. A web front-end for majordomo) then perhaps you could conribute that (and write it in php even). thanks Dave, that makes sense... i was just thinking of a mailing list totally controled through email... Like people if they want to subscribe, they send an email with subscribe in the subject, etc... There are some things that are best done in certain ways. I tend to think that php is not the most appropriate way to do this particular job. Mailing list software, in particular, is a fairly complex piece of software that needs to do a lot of things well or have major consequences (I once witnessed over 800 instances of one message in a mailing list because an admin email address on that list had been slightly mis-configured). There are a number of free packages that have been around long enough to have any serious problems ironed out. I would tend to suggest that you're better off going with one of those than trying to write something new. Of course, that presumes a desire to have a mailing list rather than a desire to learn how to write such software. If you do want to write such software you'll have to decide which MTA's you want to support and then get comfortable with how those MTA's work so you can interface your software to them. You'll also have to understand their security models so you can do it without having them become a possible spam source among other things.

RE: [PHP] strip_tags bug ?
The minor problem is that it treats a not-equals sign, , as an empty tag and strips it, unless it's explicitely ...etc... Except, of course, that when writing html you are supposed to use entities for any valid html stuff - ie. Use gt; and $lt; for and so on. As you should also use quot; if you want a in your html. The fact that various browsers will let you get away with this does not make it valid html. The argument above it a little like saying that there's a bug in php because it will get confused if you have marks inside your marks... Eg. $string = fred said wow to me; By your argument this should work because php should figure out what you mean with multiple instances of . You have a way of making it work that is well documented. Ditto for html. Of course, this doesn't stop inummerable people who, I presume, don't know any better, from usingand other stuff instead of their equivalent html entities.

RE: [PHP] dynamic pull-down menus?
That sounds very close to what I'm trying to do. Is it necessary to reload the page every time a selection is made? I've found examples of the javascript side of it on www.irt.org that helped last time I did this sort of thing. The php/sql stuff is a matter of figuring out what you need to extract and refining your queries with each new menu to get the right data. The need for page reload sorta depends on how much you want to load up the page - the more select menus you have the more possible iterations you get and, therefore, the more data you need to include in your page. Beyond a certain point you may find that you're better off doing a page reload and refreshing your select data rather than including it in the original page. Do you have examples of this that work with multiple pull-down menus? Once you have a double selection it shouldn't be a big task to extend. You may find it easier to start with by just using html/javascript and then adding the php/sql once you know the html/javascript is working fine - just keeps complexity down while you're working it out.

RE: [PHP] Re: Date?
Speaking of which. I was thinking about this this morning. Is there a part of the Unix timestamp that tells php what timezone to report. You could use the gmt-based date manipulation to do this. Reason why I ask, is I would like to offset the unix timestamp relative to where a server is to a particular user. So lets say the user is in Europe, and the server is in USA and the script is set to display date as 'H:i T', and Your main problem will be in identifying where the user is. Probably the only truly reliable way is to ask them to tell you what their time zone is. Pretty much every other method will result in a percentage of inaccurate reporting - the degree of error will be dependant on the method chosen.

RE: [PHP] the curse of the period
The directory and file name: museum/trees/admin/upload2.php The directory I want to store the uploaded file is: museum/landmark/photos/ I've found that if you need more control over directory paths than something fairly simple then you're often best off just declaring a set of full paths and using them. For example, I often use a config.php to setup database connections and the like. If I know I'm going to need to access files in different directories from different parts of a site I'll usually add something like: $server_root = /home/www/some/web/site; $web_root= http://www.some.server;; Then if you need to do an include somewhere you can be sure that something like this: Include($server_root/museum/trees/someinclude.php); Will work.

RE: [PHP] GOTO command. Doest it exist?
I do beg your pardon... But does PHP not have GOTO command? Why do you need one? In my experience, going right back to BASIC over 10 years ago, it's rarely _necessary_ to have a goto. In php I suspect you'd get similar functionlity out of either include() for creating functions. Not using goto tends to promote readability of program flow also, always a good thing imho. Each programming language is different and each has it's own advantage, disadvantages and is particularly suited to certain uses. A good programmer works with the tools available rather than worrying over language differences. Just my own opinion and I don't really expect anyone else to agree.

RE: [PHP] Else/For loop
Being relatively new to php, I discovered the following
after about 2 hours of debugging last night and was wondering why???
I had the following code:
if ( $num_results = 0 )

echo no records found;
}
else
{
for ($i=0; $i $num_results; $i++)
{
display record set
}
}
The duduction...for loops will not work inside else
statements. The question...why?
Your deduction is wrong, they do. If this is the code that you're
actually using then I suspect that your problem is more in the
conditional you've got in your 'if' statement. You aren't doing a
compare you're actually setting $num_results to 0. A comparison is '=='
rather than just '.

What Im trying to do here is not inside PHP nor MySQL books I have. I need to query the DB to look the max result in a column. That is, if I have affiliate members with ID going from 1 to 10, get the query to know that the last member added was 10 so I can add member 11 without using auto_increment, because I need to insert old members too which already have ID numbers. Is that possible? This is really a mysql question rather than a php question and would probably be more appropriate to a mysql list. In any event, if you seriously think auto_increment is not your solution here you probably need to rethink your database design. This is exactly what auto_increment is for. If someone is already in the list then you can get their ID with a select and then do an update on their row, if someone doesn't exist then you add them and ID auto_increments in the process. -- -- Outback Queensland Internet Longreach ** New Web Site Online * Queensland Australia W: www.outbackqld.net.au -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Extracting from an Array
I have a db field, type varchar, that is actually a 'date' string formatted as dd-mm-. I used type 'varchar' (rather than type 'date') since I had to accomplish other things with it. Now, however, I do need to extract the Year (the last four digits in the array). Ummm, are you sure it's an array? How are you extracting the date string from your database? Normally you'd end up with a string when you extract a varchar field from a database. I've tried to access the array $_SESSION['expiry'] but I don't know how to explode this array to extract all characters I take it you are setting this session variable from the date information in the database? Is the code that sets the session variable changing the format of the database information at all? If not then you should still have your date in the form 'dd-mm-' shouldn't you? Is there a way of extracting all characters in that array? I'm not sure you have an array to deal with unless you're talking about the result of exploding your text string. If you've exploded your string and are now trying to deal with the array then, given what you've said, $array_name[2] would probably contain the year. Alternately, if you've got the string to work with you might find it just as effective to do this: $year = substr($full_date_string, -4); This will grab the last four characters from the string which, in your case, would be the year.

I have a JavaScript function that onChange of a list box, takes the value of an option and grabs data from a MySQL table. My problem is how do I use the JavaScript var in my sql statement? Javascript is client-side, php is server-side. The only way to get something that happens in javascript to interact with something that needs to happen on the server is to reload the page and, in doing so, pass those variables back to the server. The main ways you would pass variables back to the server are either GET args in a url or POST args from a form. Perhaps your onChange needs to include an implied submit so that the form data can be passed back to the server. -- -- Outback Queensland Internet Longreach ** New Web Site Online * Queensland Australia W: www.outbackqld.net.au -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you are just including the file in what's already loading then all you need to do is make sure that $var is already set when you include the file. Including is logically the same as opening up the other file and then doing a copy/paste into the current page. It's exactly the same as if the contents of your included file was in the file that's doing the including. If you are actually trying to load a new page and pass a variable to it then you probably want to look at using header(Location: website.php?var=$var); instead.

Then installed php as downloaded from www.php.net and followed the install instructions that are included with it - also worked fine. Then installed MySQL the same way and it worked too. Apache and MySQL will install as services and run in the background all the time. They take up under 3MB of RAM when doing this.

RE: [PHP] Seperating presentation from logic
? // general_config.php $siteTitle $colBg = #FF; $colText = #FFCC99; $colLink = #EE; $colComplimentary = #CC6600; $fontHeading = FONT class=\heading\ face=\verdana, arial\ size=\3\; Wouldn't you ultimately be better off moving most of this sort of thing into style sheets and then have the designers play with the style sheets instead? What I tend to do is define style classes for various functional areas in my web sites and then my designer can figure out the design aspects based on those constraints. When you get down to it style sheets help you to stay consistent in your layouts - after all, you do want all your body text to be the same don't you? So if you define a bodytext class and then code that into your back-end it is always going to be that way. If the designer then decides that they want Times New Roman instead of Comic Sans as the body font they can change it in the style sheet and everything else changes accordingly.

RE: [PHP] PHP not working on Apache at XP Pro.
I've got Windows XP Pro OS. I installed and am running mySQL on that. However, PHP is not getting configured with Apache on it. I got the latest Apache, 1.3.24 or something, not the Version 2. Anyway, Apache runs perfectly on it. However, when i put in the required PHP lines in httpd.conf and install PHP otherwise on the system. What happens is that i get an error stating that : mod_c.php already exists, skipping Now when i remove that line, PHP does not work with Apache. If i insert that line, APACHE itself doesn't work at all. What is wrong with it? I've just recently done pretty much exactly that on my XP Pro Laptop. I must admit that I found the install.txt text file in the php zip archive that I downloaded from php.net to be just fine for getting it all working. In the end it took me something less than 20 mins to install and test the whole thing once I had all the archives downloaded. If you are getting errors I'd suggest going back and reading the install.txt again and checking that you followed the steps in it exactly - I did and it works. As the install file suggests, start more simply by excluding the extra modules until you're sure the base install is working - I did this and I suspect it helped.

RE: [PHP] Seperating presentation from logic
Wouldn't you ultimately be better off moving most of this sort of thing into style sheets and then have the designers play with the style sheets instead? What if your designer wants to change from a two column table to a four column table. Or change the menu from a vertical column on the left to a horizontal row on the bottom that's run by images instead of text. Actually, I think the idea behind what the previous poster was saying is that: a) with stylesheets they don't need to touch the HTML once they've finished with it (and handed it over to you for PHP work) b) you therefore won't need templates Mostly my original comment above was in relation to someone's response where they said they had defined a whole stack of variables for each file (eg. $fontMain, $fontCopyright and so on) and my point was specifically in relation to that. Certainly, for layout and other aspects a style sheet is not the whole solution but when it comes to display elements such as fonts and colours I'd have to say that it _IS_ the solution.

RE: [PHP] Javascript to PHP?
My apologies if this has been asked a thousand times. I've just joined the list. I has, but you get that... I can't find any information on passing JavaScript variables to PHP on the same page (i.e. not through the POST information of a submitted form). Is this because it's not possible? Short answer is no. PHP is server-side, Javascript is client-side. You can get variables from php to javascript when your php generates the page to be sent to the browser but you can only get variables back from php when you use browser to server communications (that's usually a form - be it get or post method, or a cookie). To take the load off the server, I'm trying to do a bunch of string manipulations and loops in JavaScript and then hand that info off to PHP once it's done. You'll need to create all the javascript from you php page as it generates and then wait for it all to be done client-side and submitted back to the server.

In projects that have need of such functionality I create a modules table and use that to store what information I need - normally that's a path to the module, the name of the config file for that module and any other relevant bits that the project as a whole needs to know about.

RE: [PHP] mySQL time = year 2038 [SOLVED]
Yep, I was using the DATE() function in PHP to convert a TIMESTAMP from a MySQL DB query. I was getting a year of 2038 because MySQL and PHP use different TIMESTAMP formats. $getmyTime = mysql_query(SELECT UNIX_TIMESTAMP(timestamp_col) AS yournamehere FROM myDBnamehere WHERE id = $whatever) or die(Invalid query); If you mainly need to output a date in a particular format you might find it more effective to use mysql's date formatting capabilities. Have a look in the manual for the section on DATE_FORMAT() which will let you get the date out of your table in just about any format you desire.

This won't really change speed on the client side at all - the image is the size that the image is. Changing it's display size won't change the file size. Having said that, if you're looking to set a standard width and height for an image loading in a particular location then you could probably just do this: img src=getdata.php?id=3 width=100 height=100 ...which should do what you want. If you actually want the real width and height of the image then you're probably going to have to do some pre-processing to work out the width and height first and then include them in the image tag.

RE: [PHP] Button can't see form!
The problem I have is with a page I build dynamically. The whole page is encased in form/form tags. In between these tags there are sections echoed as a result of a databasse query.

RE: [PHP] PHP/MySQL -- Date/Time Confusion
Which method is the best way to store date/time in MySQL and then which PHP command is the best to use to convert that date to something useful? Get comfortable with MySQL's date functionality and you'll find that you don't often need to do the date comparisons and manipulation in php at all. MySQL lets you store date/time stuff as date, time or timestamp formats (off-hand, haven't referred to the manual here) that will store the data for you. You can manipulate this date information in your sql query using things like DATE_FORMAT() and the like. Check the MySQL manual for all of those (chapter 6 or 7 I think it is). If you're mostly doing data extraction based on date criteria then you'll find it works best as sql queries basically.

RE: [PHP] mysql LIMIT
can I use limit to show the 2nd record on without knowing how many more records there might be? also, what happens if I set the limit in a mysql statement (LIMIT 5,10), but there are only 3 results? 7 results? My answer would tend to be that you should try it for yourself and see... But anyway, without having tried it myself recently, the first question is that you could use LIMIT (2, 1) and you'd probably get what you're trying for. As for the second question, you'll only get what records there are. If your limit excludes all possible results then you'll get no result (ie. If you use LIMIT(5, 10) and you've only got 3 records, then you won't get anything back at all. If you've got 7 records then you'll get the last 3 of them). But in all honesty, you could have worked this out for yourself fairly quickly with some simple testing of your own.

This is really a database question rather than a php question and you haven't said which database you're using so it's hard to give a definitive answer.

Oh, I just checked the manual: In MySQL Version 3.23, you can, however, do: SELECT * FROM table_name ORDER BY RAND() I still don't understand how does Order by work with a decimal value!!! I don't pretend to have all the answer. I just know that I had reason to work this one out for myself a while back and when I consulted the MySQL manual it gave sample code on what to do in MySQL to achieve this result. I accepted that fact and used it. I haven't needed any deeper information on this one so I haven't looked.

RE: [PHP] datetime field - still a newbie
I have a datetime field in one of my mysql tables...when displaying some of my records I want to display the date in the aforementioned datetime field, but if the date is today I want to display today instead. If the date is yesterday I want it to display that so I how do I compare the date in my record to todays date? Thanks First up, extract your date as part of your query in a standard format - if you're looking to do date manipulations you're probably going to be benefit from extracting it as a unix timestamp. Once you've got your date information, along with whatever else you're extracting, you can then process it in php. You'll most likely have some sort of while() loop to increment through your query data. While you're incrementing through you can do an test the date information against today and yesterday. Have a read of the php manual for date() and mktime() as you'll almost certainly need to use these two functions. Basically what you'll need to do is test to see if the date information from your database query is the same as your date information based on working out what today or yesterday are when expressed in the same format as the date information from your database. The rest is pretty much display stuff - substitute date information for appropriate words as required. Hope that heads you in the right direction.

RE: [PHP] Paying Job...
Do you charge by the page, script or by the hour (that would be nice). We do this sort of thing in, basically, one of three ways... 1. Client gives us a budget and we give them a clear idea of what that budget will get them. 2. Client gives us a good idea of what they want to achieve and we provide a quote to get them there. 3. Client gives us all the content they have and we go to it and write an invoice for our work when we are done. Number 3 is pretty rare. For 1 and 2 we always get approvals on the work as we go and we always work to the budget that we've got (either from their end or from our quoute). Documenting what is covered within the quote is important so that you have a way to increase the invoice if the client comes back asking for added features that were not originally included. We've found that most clients like the idea of a fixed fee so they know what they are up for. The key to doing this is to make sure that you don't end up losing out by not making clear what that money will buy.

IE in particular is very good at fixing broken html as it loads a page and this can hide otherwise serious problems with html. If you're going to output something to a browser then you _really_ should make sure it's valid html. At the very least that would mean including: html head/head body/body /html in a page.

There are ways to make sure your wonderful web design will still work if javascript isn't present. There are design rules that will leave your website mostly navigable to people using text-based browsers. There are ways to degrade capabilities gracefully, and ways to disable badly. An example of badly is to basically tell someone to bugger off because they don't have 'xxx' (where 'xxx' is whatever technology you want to use, be it javascript, java, flash, etc, etc). If they can figure out you don't have it and give you a message about it then they can insert something that leaves the site functional - even if not as nice an experience.

RE: [PHP] File upload problem
-Original Message- I'm curious, I keep seeing people say that that tag is /necessary/, but I've never had to use it in the upload forms that I've built and they work just fine in Opera, NN IE. Good question. To be honest it's been a while since I looked, I built a file upload function as part of a standard set of functions that I include in projects and then stopped worrying about it. As a result it's been a some time since I looked at that sort of thing. I recall including it for a reason but don't exactly recall the reason. AFAICT from the manual that tag is only to advise the browser to limit the size of the file being uploaded, nothing to suggest that the absence of the tag would prevent uploading. I guess that anything that causes this sort of thing to happen on the browser is going to help. I know I'd be fairly unimpressed if I sat waiting for a 2MB file to upload only to find that the limit is 1.5MB or some such. At least if a client-side limit is given the browser can do something about it. Not that I actually recall testing that either - I've so far only used file upload capabilities on intranet projects where I have fully switched 100MB and the like.

If you want you can think of a immaginary tool that makes a website load twice as fast, need the half web space and makes the website look nicer, of course at lower OK, if you're producing something with a significant commercial value then spring for the dollars to pay for zend encoder and use it. Seems like some people want it both ways - my code is different and unique and has commercial value in and of itself but I'm not prepared to spend real dollars to protect it, I want free code to do that. I suspect that many people in this situation have an overly high opinion of their code and, in reality, there are open source or free alternatives that do much the same (albeit elegant and easily customisable or whatever) and, as such, not worth spending the money on zend.

RE: [PHP] Genus who came up with Self Destruct Code Copy Pro tection
Obviously most coders are in the middle ground. They are not writing the killer app of all time but is of significant value. I don't know what people on here are charging but I can't add $2880 a year to my overhead for the zend encoder. Plus add $1875 per cpu for the zend accelerator for each project. My personal opinion is that your code is either worth protecting or it's not. If it's worth protecting then that protection comes at a price. Sorry, commercial reality time here. If you are going to operate on a commercial basis then you have commercial decisions to make. This is one of them. So you're bidding for a project and the guy asks, Let me get this straight, you're charging me more then everyone else and I won't be able to edit the code? I think you would simply pricing yourself out of the market. If that's what you're going to do then yes. Ask yourself what people like ISC (the people who do bind and sendmail do to make a living - after all they have seriously commercial quality products available for free) or people like RedHat (who give away their linux distro for nix if you want to download it, or pay a small fee to whatever company downloads it and sells CD-R burns of the iso's). People can, and do, make money giving away their code. When you figure out how they are doing it, and the philosophy behind it, then maybe that will ease these fears. I can pretty much guarantee that if you come up with a killer app in php that no matter how protected it is you will not be the only one with a version of killer app for long. Someone else will come along and write something similar - if that person does it open source then there's also a fair chance it will end up being better than your product due to shear weight of numbers contributing to it. In the end all this, and more, are your decisions. Of course, if you choose not to do this commercially then it's a whole different setup with different goals and so on. For the record, I pretty much release what I do to anyone who wants it. Not that my efforts are of a standard that they are worth all that much per se - they are often fairly specific to the project at hand and not overly portable (in their released format). I do have one intranet application under development for my own business that may well end up with a strong commercial basis but it will never be a single product but part of a much larger package my business is currently planning. Even then, the code associated with that project may end up open sourced in some way. Let's face it, there's even a move to replicate the zend encoder in open source. As has already been said, there also has to be a level of trust between you and your client(s) if you are going to do business with them. If your clients see you as overly paranoid about your work they may end up not wanting to deal with you anyway. If you're that paranoid about losing control of your work offer it on a complete solution basis - either you host it on a machine that they have no back end access to or you provide the hardware as well as the software and have it locked out in such a way that the code is not easily stolen.

RE: [PHP] problems with form/form
I've only just picked up on this thread, but why not put each form inside a td element? i.e. table tr tdform ... /form/td tdform ... /form/td /tr /table A closing /form includes an implied p so if you keep it inside your td/td you'll end up with extra space in your cell.

RE: [PHP] Genus who came up with Self Destruct Code Copy Pro tection
So I should buy a commerical product from zend to protect my code but since my code will be reversed engineered anyways then what's the point of buying from zend? That's your choice. It's also my point. If you can't be 100% secure then perhaps you should be looking at what you're trying to do. Some observable facts: 1. Some companies remain, from what I can tell, highly successful and can give away their source code for free. 2. Some companies remain, from what I can tell, highly successful without giving away any of their source. 3. Some companies fail, even if they are giving away their source. 4. Some companies fail, even if they don't give away their source. The conclusion I draw from that is that protecting or giving away your source is not a single make or break decision for a company. Rather, there are a myriad of decisions involved, of which the status of any source code is but one. Protect it, don't protect it, by itself it doesn't mean squat. In association with other things it might. For example, if you aren't prepared to pursue, in the courts as necessary, your closed source proprietary code then sooner or later someone will figure that out and take it for their own use. Do you think Microsoft would be as successful if it wasn't as agresive about protecting it's intellectual property? Speaking only for myself, I believe the effort involved to be not worth it, so I have no current intention of trying to protect, encode, conceal, booby trap or whatever any of my code. What you do is your business. You'd probably do well to understand the implications first - what are you protecting? Why? How far will you go to protect it? Will you take legal action?

RE: [PHP] Layout Help
Anyway, I have a stack of 76 playlists I need to consolidate and display.

It's really more an sql question than a php question but... Have a table that contains dates and names of shows. Have another table that contains artists. Have another table that contains songs. Have another table that contains tracks. Each of these also has an ID in addition to the other data in the table. Have a linking table that contains artist ID's and song ID's. This lets you, for example, look up all songs for a particular artists or, potentially, all artists for a song. Have another linking table that contains song ID's and album ID's. This lets you relate songs to albums and, through the previous table, artists. This way, though, you can have compilation albums with multiple artists on a single album. Last of all create another linking table with song ID's and show ID's. This gets you songs for a show but, through the other linking tables you get information on everything else. For any additional information just store it in the relevant table (ie. If you want to keep track of song lengths then it would go in the songs table, if you wanted artist bios that would be in the artist table and so on).

What happens if you feed this function a designated string that you

get date info on and then call the function. If you get the right thing
you know your function is doing what you expected.
$filename = (combined_log);
//fopen ($filename, r);
$fcontents = file($filename);
$limit = 1;
for ($i = 0; $i = $limit; $i++)
{
$line = $fcontents[i];
Try echo'ing $line to make sure you actually had something happen.
if (!empty($line))
{
$currentdate = getmydate($line);
echo $currentdate;

But surely, ASDL, cable, the backbone and decent intranets must all do hardware compression, don't they? Or are they secretly not very keen on decreasing network traffic? Perhaps there's an element of confusion in technologies. A modem is an analogue device. It converts a digital signal into an analogue one to transfer it over a phone line as audio. As such, it is capable of being compressed due to the nature of the signal (being audio and all). A digital network link (which includes ISDN, ADSL and the backbone link stuff) is just that - a digital link. No conversion to analogue takes place. On a digital link you're moving packets of data. I doubt there's much scope of a packet of data that would typically be under 1k in size (going purely from memory here and quite happy to be told otherwise). Different technologies involve different concepts basically. CYA, Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Date and time functions
I am on the East Coast of Australia. I'm in central Queensland... Do you know if by default if the date/time display will display only East coast Australia time, or will display from the user's time zone? eg Will USA users see the Australian time or their own time? Would this cause a issue with timestamping an order when it comes to writing to a mySQL database? I presume we're talking about php date/time stuff here? In that case, php gets it's date/time from the server it is running on. If your server is on the east coast of Australia then you'll have local time for east coast of Aust. One way to deal with this would be to take everything back to GMT/UTC/Z and use that instead. Then all you need to do is add an appropriate adjustment to get local time where ever the browser is - of course, you may not easily be able to figure that out so it's not necessarily a perfect solution. In the end, the solution will depend on your requirements. What are you using a timestamp for? If it's purely as a reference point in database queries (i.e. all changes in the past two days, or 10 mins) then it probably doesn't matter all that much. Your database will be updated from your server and your server has a consistent internal time. If your application is date dependant in an absolute way then it becomes a little harder I guess. Although, you'd also ask yourself how relevant it becomes to someone in a vastly different time zone - i.e. if you're doing a local event calendar (which just happens to be one of the things I'm doing right now) then the fact that an event might be happening right now instead of this time tomorrow (from the perspective of someone on the other side of the world and their time zone) is largely immaterial - they aren't going to get there anyway. Perhaps the simplest approach to that is to include a time/date reference. If you're going to include date information let the browser know the context. So, you advertise the next 'xxx' event will be at 3PM 17 May and tell them that it's 10:30AM on 17 May right now. Leave any relevant math up to them. Can someone suggest a script that may give me the option to offer both time zones to the user? You could probably do something in javascript (being client-side it knows the time in the browsers' location) to work out equivalencies and conversions if you like.

RE: [PHP] Q:Anybody using PHP directly on Mac-OSX???
So, anybody out there have PHP installed on their local home desktop Mac OSX box able to test by a quick preview in browser from say an app like BBedit? I went to: http://www.google.com/ I entered the following into their dinky little search box: mac osx apache mysql php installer I got a total of 333 matches. The first one is an article on www.faqts.com about how to install php/mysql/apache on Mac OSX, the thire is a pre-built binary for MySQL. Google also asked if I actually meant to search for: mac os x apache mysql php installer So I clicked on that link and it resulted in 3600 matches. The first page of which included more matches which look relevant. So, yes, it's possible. A little research, and I feel I must stress the _LITTLE_ part, would have you your answer.

RE: [PHP] Confused about which function to use with forms/database
I've read the documentation but am still confused about what to use when. When passing data from forms to database, which do I use? When retrieving data from database to display in forms, which do I use? Kinda depends on what you're using the data for really. If you don't care about preserving formatting or any sort or keeping any html tags that are included then strip the lot out before you drop it into your database. If you want to keep it all then you'll need to be more selective. As a general rule, though, you'll need to 'escape' anything that your database won't like - this is typically the ' and chars. Addslashes() will do that for you. Anything else you want to do depends on what you need the data for. When you suck the data back out you'll obviously need to stripslashes() to get rid of the 'escape' chars you added above. Then you'll also need to do any other processing required - for example, converting \n to br if you're just displaying data on a page (nl2br()). If you're actually sucking that data back out to go into a textarea in a form or something then you won't do that. Unless you're particularly careful it's probably worth stripping out all html tags anyway as they offer the potential to have someone include scripting. When displaying to a html page you probably also want to convert special chars to html entities using htmlspecialchars(). I may have missed some stuff here, didn't bother looking at a manual while writing this but I hope you'll get the idea.

RE: [PHP] Confused about which function to use with forms/database
When you suck the data back out you'll obviously need to stripslashes() to get rid of the 'escape' chars you added above. Nope, because the escape characters don't actually get added to the database. When the database's command interpreter sees it, it removes the escape character (\) before inserting the string into the database. So it's back to its original form then. When you retrieve it, you'll just get: Ah, fair enough. Obviously, I've never actually tested that particular behaviour. I'll keep this in mind for future reference though.

RE: [PHP] random order by id
i have a db and a table with id and questions now i want these questions to be listed in a random order, is there a way to format my SQL query or do i need some PHP work to? It's best achieved in sql: SELECT ID, Question FROM Questions WHERE Some = Condition ORDER BY RAND() LIMIT 10 Will get you up to ten randomised questions based on your 'where' condition.
