Brent. Hi I'm wondering how I would go by making some sort of scrip for my website that loads random content from different files on my web server. Preferably php coding and maybe some mysql coding for an example I would like to have different folders on my web server lets say I have ( File 1 ) and in file 1 I have files named "cover.jpg" and "description.txt" and maybe some other files too and the same thing in other files on the web server So how would I go by making some thing that can load up these different files on the web server, like I said that will load up the content in each of the files every time the page refreshes or press of a button. Thanks Hi to everyone , I have used PHP for some basic things in my previous website design but am now venturing into another website for which I have a more complex use for PHP. I plan on making business directory for my local area. People will click on the area of their choice followed by the business type that they require. Then on the results page, they will have a list of all the business types in that particular area. What I would like to be able to do is rather than have the results displayed on the page like this : A Plumber xxxxx xxxxxx Tel: xxxxx xxxxxx Web: xxxxx xxxxxx E-Mail: xxxxx xxxxxx Best Plumber xxxxx xxxxxx Tel: xxxxx xxxxxx Web: xxxxx xxxxxx E-Mail: xxxxx xxxxxx Top Plumber xxxxx xxxxxx Tel: xxxxx xxxxxx Web: xxxxx xxxxxx E-Mail: xxxxx xxxxxx I would like it so that the same businesses are displayed on the page but either: 1) In a random order each time someone loads the page or 2) In a random order changed every hour The aim is so the businesses all have a shot at appearing nearer the top and aren't penalised for the 1st letter of their company name. Any help on this would be much appreciated, Thank You This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=315227.0 This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=314527.0 This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=310934.0 Stop posting non-PHP questions in the PHP Coding Help section.

So i was told to look into using fopen and random.org to generate a random number. Anyone have experience of this and perhaps a code snippet for me to look at and possibly use? help will be appreciated. Hi
I try to echo out random lines of a html file and want after submit password to whole content of the same html file. I have two Problems.
1st Problem When I echo out the random lines of the html file I don't get just the text but the code of the html file as well. I don't want that. I just want the text. How to do that?
for($x = 1;$x<=40;$x++) {
$lines = file("$filename.html");
echo $lines[rand(0, count($lines)-1)]."<br>";
}
I tried instead of "file("$filename.html");" "readfile("$filename.html");" But then I get the random lines plus the whole content. Is there anything else I can use instead of file so that I get the random lines of text without the html code?P.S file_get_contents doesn't work either have tried that one.
2nd Problem:
As you could see in my first problem I have a file called $filename.html. After I submit the value of a password I want the whole content. But it is like the program did forget what $filename.html is. How can I make the program remember what $filename.html is? Or with other words how to get the whole content of the html file?
My code:
if($_POST['submitPasswordIT']){
if ($_POST['passIT']== $password ){
$my_file = file_get_contents("$filename.html");
echo $my_file;
}
else{
echo "You entered wrong password";
}
}
If the password isn't correct I get: You entered wrong password. If the password is correct I get nothing. I probably need to create a path to the file "$filename.html", but I don't know exactly how to do that.
Hi, I will start off trying to explain what I am trying to make the best I can. What I want to create is a script that gets the gold value from this website: http://www.lbma.org.uk/pages/index.cfm?page_id=46&title=current_statistics and then save it to a variable which I will use to calculate values of different gold karats. Here is the content in bold I need on the website I linked: Quote LONDON GOLD FIXING USD GBP EUR AM 1588.00 1005.127 1251.083 PM 1589.50 1004.741 1249.803 So what help do I need? Well, I don't expect you to figure out the calculating part for me but some help how to get that content pointed out above and save it to a variable is what I would appreciate getting some help with. I don't know much PHP, only some and I have been trying to figure this out for a day now without any success. I suppose php get contents and/or curl should be used here but I don't know how really. I would very much appreciate the help I can get on this. Thank you! This is the Code i am using.

How tolerant is PHP from generating a random output from 1000s of entry columns in a mysql database. I would like to make a script that would potentially pick one of a 1000 results at random. is this a problem with being ran multiple times? Wow, I have no clue what I'm doing.. I'm trying to make a random game and if you roll a 6, you will win 500 rp and I'm trying to insert the 500 rp into the user who is logged in ($_SESSION['username'). But I... just don't know where to begin. Here is my crappy coding that I just.. am stumped on: <p><?php $dice = rand(1,6); if($dice == 1){ echo "You rolled a <br><b>1</b>"; }if($dice == 2){ echo "You rolled a <br><b>2</b>"; }if($dice == 3){ echo "You rolled a <br><b>3</b>"; }if($dice == 4){ echo "You rolled a <br><b>4</b>"; }if($dice == 5){ echo "You rolled a <br><b>5</b>"; }if($dice == 6){ echo "You rolled a <br><b>6</b>"; } $winner = "500"; if($dice == 6); { include("haha.php"); $cxn = mysqli_connect($dbhost,$dbuser,$dbpassword,$dbdatabase); $sql = "INSERT INTO Member (rp) VALUES ('$winner')"; mysqli_query($cxn,$sql); } ?> |
