PHP - Randomly Invert/negate Section Of Image

I am having an issue in which fopen randomly generates either timeout or "failed to open stream" errors when trying to get stock quotes from yahoo finance.

Here's an example.

<b>Warning</b>:  fopen(http://finance.yahoo.com/d/quotes.csv?s=NFLX&amp;f=sl1d1t1c1ohgv&amp;e=.csv) [<a href='function.fopen'>function.fopen</a>]: failed to open stream: HTTP request failed!

This issue occurs sporadically; sometimes it's fine, other times it errors out causing the quote to fail.

Any ideas on how I can resolve this? Thanks very much.

Hello all I have a form for a meeting unable to attend log.
An attendee calls in to say they will not be able to make meeting and the form saves the reason etc into a db and infroms (via emails) all staff members who would have attended of the cancelation.

It works but for some reason the record saves twice in the db on occasion and I'm unsure why.

The loggers fills in some deatils on a form called log.php and then clicks save which goes to the following page:

Code: [Select]
<?php
$auth = $_COOKIE['auth'];
$login_id = $_COOKIE['login_id'];
header("Cache-Control:no-cache");
if(!$auth == "ok")

exit();
}

include("../php_include/functions.php");

$absent_date = $_POST['absent_date'];
$call_time = $_POST['hour'] .":". $_POST['mins'];
$reason = (! get_magic_quotes_gpc ()) ? addslashes ($_POST['reason']) : $_POST['reason'];

Can anyone shed some light?

Hi,

I have an array of items and I randomly want to remove one from the array. What's the easiest way to go about this?

15 rows selected from the table.
I want to randomly display an ad between them.

Here's the code:
Code: [Select]
$count = 1;   

(mysql select rows)

$number = rand (1,15);
if ($count == $number)
        {
echo 'ad code


                     ';
}
$count++;
I want the ad to be displayed only once and in the above code, depending on the generated number by rand() matching the $number the ads will be displayed more times.
How can I limit this only to one?

If I have an array, $array, how can I loop through it (e.g. with a foreach() ) .. but just do it randomly?

So each time, random entries of the array are used and not necessarily in order.

I need a simple code like
Code: [Select]
$test1="1";
$test2="2";
$test=$test1|$test2;
echo $test;to randomly catch the value of strings $test1 or $test2; as each time running the code, echo shows randomly one of the strings.

Could you please guide what the third line should be ?

Hi there,

I'd be ever so greatful if someone could help me please. I'm really trying to get my head around working with arrays and could really do with an example in a context i fully understand.
I have made a test page for this and made a query that will search for appropriate records in my database:
  Code: [Select]
<?php $colname_Class = "3";
$colname_Ships = "-1";
if (isset($_SESSION['MM_Username'])) {
  $colname_Ships = (get_magic_quotes_gpc()) ? $_SESSION['MM_Username'] : addslashes($_SESSION['MM_Username']);
}
mysql_select_db($database_swb, $swb);
$query_Ships = sprintf("SELECT * FROM ships WHERE PlayerName = %s AND Class=%s AND Template='1'", GetSQLValueString($colname_Ships, "text"),
GetSQLValueString($colname_Class, "int"));
$Ships = mysql_query($query_Ships, $swb) or die(mysql_error());
$row_Ships = mysql_fetch_assoc($Ships);
$totalRows_Ships = mysql_num_rows($Ships);



echo $row_Ships['ShipID']; echo ' ';
echo $row_Ships['ShipName']; echo ' ';
echo $row_Ships['Class']; echo ' ';
echo '  ';
echo $totalRows_Ships = mysql_num_rows($Ships); ?>

After i made the query i echo out the ShipID, ShipName and Class from the queey which displays:

5 New Ship 3 1

So you can see the ShipID = 5, the name of the Ship is New Ship, its Class is 3 and there is only 1 record found in the database that matches the search criteria.

Lets say there are 10 records in my database... What i really need to do is  make an array of the outputted results, determine the number of records and then to randomly choose 1 of the results from the array.

Can you help me please?? If i can see an example in this context i feel i'd really learn something here.

If you can help, please do because im well stuck.

Thank you

Tom

I'm trying to write code that will let me pull 10 out of 15 images out of a folder and display them on my site. The images are all different, and I don't want dupes to show. So far, I have the following code figured out:

---------------

$s = array ("image.jpg", "image2.jpg"); // as many images as you want
$n = rand(1,len($s)); // randomly pick a number between 1 and the
length of the array
echo "<img src='". $s[$n] .'">"; // create an image tag for the randomly selected imagine (value of the randomly defined key)
array_pop($s, $n); // This piece isn't right, it needs to EXTRACT and delete the $n array element.

// Next random image
$n = rand(1,len($s));
echo "<img src='". $s[$n] .'">";

---------------
Any ideas what array_pop should be to work properly?

Thank you for the help!

Say I have two variables like below. I basically want to select one of them, but through random choice. How do I do that?

$orange = 'Orange';
$apple = 'Apple';

 

Hey, This is my first day with PHP and I'm given an assignment by my professor. Assignment is a very basic game, all i have to do is give 2 random numbers, and add them, and check if the user has submitted the correct answer.    So i thought like this;   1-    first php file generates two random numbers 1.1- user submits the sum of those numbers   2-    second php file, gets the sum of the random generated numbers and checks if the submitted value is right.   I've come up this far;   <?php
echo "<html><head><title>calculation game!</title></head><body>";
echo "<h1>first number is</h1>";
echo (rand(100, 450));
echo "<h1>and the next number is</h1>";
echo (rand(100, 5000));
echo "<h1>now add the numbers and submit your output here!</h1>";
echo "<form name = \"myfirstform\" action  = \"formprocess.php\" method = \"PO$
echo "Enter data<br>";
echo "<input type = \"text\" name = \"firstdata\">";
echo "<br> <input type= \"submit\" value = \"Let's check!\">";
echo "</form>"; ?>      Now my problem is about; how can I keep those generated numbers and add them up. I've been digging all through the internet for syntax and php scripts, but I couldn't find an answer that helps me.    Thanks in advance.

I am working on a quiz app

image 1 shows the index.php page
image 2 shows the first question
image 3 shows the second question
image 4 shows the third question
image 5 shows the result after completing the quiz
image 6 shows the database 'quizzer' and its tables
image 7 shows the 'questions' table
image 8 shows the 'choices' table

THIS LINK CONTAIN ALL THE CODE (and images) I HAVE DONE SO FAR

https://www.mediafir...o7f5q0fe6y/quiz

1.Now my question is how to select the question RANDOMLY from 'questions' table along with 'choices' (by adding code to the existing file or create a new one).

2.If user refresh/reload the page before starting ('Start Quiz') or click 'Take Again' after finishing the quiz, the question should appear randomly.

3.Basically I want to change the order of question appearing in the browser each time I refresh.

4.My work so far is mentioned above.........Please help me with this "RANDOM" problem !!

P.S - Will it be possible, by creating a random function in PHP which will check for repeat questions in a session and check for the 'id' of the question and if it is new display it on the page.

If so what should I do and if no then how to do?

Hi there i would like to send my clients a randomly generated order code by email i have had no success so far and was wondering how to do it.
Any help would be great!

Thanks,

I've managed to isolate a problem I'm having with my php script. It would seem the script randomly restarts itself with blank post data while it's running.

I've managed to mimick the problem using a very basic php script which just pauses and writes to a log:

<?php

$q = $_POST['q'];

if ($q==""){
  writelog ("MISFIRE!!!");
  die;
}

writelog("\n*** Error check started ***");

for ($i = 1; $i <= 50; $i++) {
   writelog ($i);
     sleep(rand(2,20));
}

 function writelog($towrite)
{
  $tdate=date('d/m/Y H:i:s');
  $file = 'log/testlog.txt';
  $current = $towrite." --- ".$tdate."\n";
  file_put_contents($file, $current, FILE_APPEND);
}

writelog("*** Error check ended ***");
?>

To rule out any problems with my AJAX htmlhttp requests, I simply send the script some irrelevant post data using Chrome's Advanced Restful client.

This is the ouput of the log from an example test run:

*** Error check started *** --- 05/06/2014 18:27:30

1 --- 05/06/2014 18:27:30
2 --- 05/06/2014 18:27:44
3 --- 05/06/2014 18:27:49
4 --- 05/06/2014 18:27:59
5 --- 05/06/2014 18:28:04
6 --- 05/06/2014 18:28:22
7 --- 05/06/2014 18:28:33
8 --- 05/06/2014 18:28:39
9 --- 05/06/2014 18:28:52
10 --- 05/06/2014 18:29:08
11 --- 05/06/2014 18:29:22
12 --- 05/06/2014 18:29:30
13 --- 05/06/2014 18:29:43
MISFIRE!!! --- 05/06/2014 18:29:46
14 --- 05/06/2014 18:29:56
15 --- 05/06/2014 18:30:07
16 --- 05/06/2014 18:30:09
17 --- 05/06/2014 18:30:15
18 --- 05/06/2014 18:30:32
19 --- 05/06/2014 18:30:52
20 --- 05/06/2014 18:30:54

Note the logged "Misfire" after the 13th entry.  This shows the script tried to run again with blank post data, the same problem I'm having in my more complex script.

Why could this be happening? It's not anyone else calling the script, nobody knows about the site and I've ruled it out by logging the IP in my real script.

Hi All,   I'm looking to update a mysql column weekly, where by 5 randomly selected rows are given a new random number, from between 1 and the num_rows / 5. This cycle is looped again until all the entries have a new random group for the week. It is to help mix up the players for teams for 5 aside. It needs to be able to accomodate the posibillity of the num_rows not dividing exactly by 5, using ceil perhaps?   As an example   Name Group  a 1 b 2 c 1 d 1 e 1 f 3 g 2 h 1 i 2 j 2 k 2   Then Next week Name Group  a 2 b 1 c 2 d 2 e 1 f 2 g 3 h 1 i 2 j 1 k 1   I hope that makes sense. It'll be automated via cron job. I've been really struggling with it, this is as far as I have got.   $totalgroupsraw = $num_rows /5;
