PHP - Help Adding Test To Output

write the algorithm to draw a sphere, the function should have parameters
   1. diameter (how many line)
   2. character (use which character to draw)
   
   eg, draw_sphere(10, '8') will produce:
   
                    88888
                 8888888888888   
               8888888888888888888
              888888888888888888888
                      88888888888888888888888
                88888888888888888888888
              888888888888888888888
               8888888888888888888
                 8888888888888   
                    88888
            
   the above is a sphere of 10 lines, which is drawn using the character "8"


i cant figure out how to do it, thanks in advanved!

Hi so i've been learning php for 3 mouth now by reading php 6 Bible and watching lynda and so on... i was looking for a job in few past weeks and i found out i don't have that kind of self confidence to go for it ! you know when they say : PHP Project Manager , it scar's me... the thing is , i know all about basic to medium php , array...MySQL....all those essentials but i don't know what do they want from a php web developer . so i began to search for intern job somewhere and i told myself i should bust my ass 24/7 for few mouth and after that i ll be real php guy and it seems like there is no place to reach not  php but almost all programming languages a year ago i was searching for the same thing but in networking section and there was 100's of intern ship jobs but in programming there is none ! so i want some one to give me (us) simple to pro real life projects . what do they want php junior or senior developer's for ? what do they do? what is the most common needs ? what is the most essential things to know? what is a hired php developer should do in the office? some people doesn't need you in the office and want you to work from home , they give you project's , what's that? is there any source in the web to offer what is need ? i know its too much , but this was my last option , so if anyone can help i would practically owe him/her my whole future salaries...

Hello All happy new year

I am trying to make a php page that detects if something is plugged in to the ethernet port.
This would be complex if not impossible. I however managed to do something similar the device
that will be plugged in has a static address 192.168.1.1. so I created a ping that says if the device is up or
down.

function ping($host, $port, $timeout)
{
  $fP = fSockOpen($host, $port, $errno, $errstr, $timeout);
  $status;
 
  if ($fP)
  { echo "Device is ready to accept data";}
  else
  { echo "Device Down - Retrying connection"; }
} 

What I would like to do is have a script that is constantly checking is the device is plugged or when it is not
(so sort of a loop or auto detect). The idea is to have an image with the device up or down.

Regards
and a happy new year

I have an issue that with some testing on an Access  class with a method getControlAccess it should only return true or false but as soon as I place a string of any sort
into the return my tests always returns true. Any help to point out if it is the way I am testing or the way I have written the method would be great. In the example
below it would return true.


In one class I have this method
Code: [Select]
class Access{
public function getControlAccess(){

return   'I am stuffed';
}
}

In the second class I have this
Code: [Select]
class AccessTests extends Access{
public function controlAccessTest(){
$return = "<ul>";
 
if ($this->getControlAccess() == TRUE){

$return .= "<li>getControlAcess should be true and is returning:<b> ". $this->getControlAccess() ."</b></li>";

} elseif ($this->getControlAccess() == FALSE){

$return .= "<li>getControlAcess should be false and is returning:<b> ". $this->getControlAccess() ."<b></li>";
} else {

$return .= "<li>getControlAcess is really stuffed:<b>". $this->getControlAccess() ."<b></li>";
}

$return .= "</ul>";
return $return;
}

public function setAccessTest($set){
return $set;
}

}

Hey Guys.   Im trying to show if the selected user has had all the required tests they need so they can have a treatment at a hairdressers.  For example the client needs to of had a skin test before they can have their hair dyed.  Im struggling on showing which tests the user still needs to have   Currently I'm working with 3 tables.   The treatmentTest table which stores all the required tests   treatmentTest idtreatmentTest   the user table which has the users details   user iduser   and the usertest table which stores when they had the test and if it has expired (if it has expired is set to 1)   userTest iduser idtreatmentTest expired     so I need this box to pop up with a warning on each test that is still outstanding but I dont want it to show if there are no tests needed. I obviously need to loop through the results of my query but the query its self is confusing me...

  <ul class="list-unstyled">
                     
                        <li>[treatment Name]</li>
                        
                      
                        <li class="text-italic text-muted">Expired [date]</li>
                        
                        <li><a href="#" class="btn btn-success">Update</a></li>
                        
                    </ul>
 

First I tried looping through all the treatments then inside that loop writing the following

 
<?php do {
  //now foreach treatment test get the resulting test from the usertest table
 
 
if (isset($row_testReq['idtreatmentTest'])) {
 $col_userTest = $row_testReq['idtreatmentTest'];
}
 
if (isset($_SESSION['cClient'])) {
 $colname_userTest = $_SESSION['cClient'];
}
 
if (isset($expire)) {
 $colname_userTestExpire = '1';
}
 
mysql_select_db($database_dbconnect, $dbconnect);
$query_userTest = sprintf("SELECT * FROM userTest WHERE idtreatmentTest = %s AND iduser = %s AND  userTestExpire=%s",
GetSQLValueString($col_userTest, "int"),
GetSQLValueString($colname_userTest, "int"),
GetSQLValueString($colname_userTestExpire, "text"));
$userTest = mysql_query($query_userTest, $dbconnect) or die(mysql_error());
$row_userTest = mysql_fetch_assoc($userTest);
$totalRows_userTest = mysql_num_rows($userTest);
   ?>
            <li class="list-group-item">
              <div class="col-sm-2"><i class="fa fa-2x fa-close text-danger"></i></div>
              <div class="col-sm-9">
               <ul class="list-unstyled">
                     <?php if($totalRows_userTest>0){?>
                        <li><?php echo $row_testReq['treatmentTestName'];?></li>
                        
                      
                        <li class="text-italic text-muted">Expired <?php echo $fn->sqlShowDate($row_userTest['userTestExpire']); ?></li>
                        
                        <li><a href="client-treat-test.php?i=<?php echo $row_testReq['idtreatmentTest'];?>&t=<?php echo $row_testReq['treatmentTestToken'];?>" class="btn btn-success">Update</a></li>
                       <?php } ?>

                    </ul>                                  </div>               <div class="clearfix"></div>               </li>              <?php } while ($row_testReq = mysql_fetch_assoc($testReq)); ?>                       this doesnt work properly at all. It gave me all the treatments that have expired but if a new treatmenttest was added it wouldnt display that there was a test required.     Does anybody know a different way?  I also tried getting all the treatments then all the rows in the userTest table then comparing what the differences where but I struggle with arrays comparisons and im not even sure that was the best way to go about it.  Am I going to need two queries? One like the loop above and one that looks for expired treatments and one that looks for treatments the user hasn't had or can this be done in one and if so how??

I have a class I use to handle my various DB objects.  I want to close any connections, if needed, in my destructor.  I want to do this even though I already know the connection has been closed previously.  What I am looking for is a way to test the $connection variable I have to see if it's in need of closing.  I can't figure out how to do this.


if (isset($this->connection))
{
    echo "is set";
}
   
if ($this->connection)
{
    echo "here";
}


The above would output "is set" and "here", because in both tests say the already closed connection is still there.  Can anyone offer any help?

this is pretty decent right?

I want to do a test while refreshing the page 100 times with 500 rows in a table, and then without 500 rows in a table and with different kind of php code, i need to do some type of testing to get results back in to show which way is faster for mysql/php.

Any idea how to do this any scripts out there or a built in php/mysql function?

Thanks

I can't seem to figure out how to calculate the score the user gets when they hit the score button.

I figured it would look something like this...

$result_score = $right / 9 * 100.... but I've tried a few methods and I can't seem to figure out why its not working.


Here is my code for the application....

Hey guys,   I've tried my hardest to create an online game, give it a whirl. i'll unpause when we get to 20 players. There's a help page to get you started. Post here with any bugs or comments!   http://www.delusionalkev.com/sn/   Thankyou   http://www.delusiona...com/sn/text.txt

I have a form that is populating fields based on a database query.  I am then trying to update the database based on any changes made in the form and passed through a POST action.

The problem I am having is with the block where I declare short variable names for the $_POST variables that will be passed when the user hits the submit button.  For each variable declaration I get an error message like this:
Quote

Encountered error: 8 in mbr_profile_updt_form.php, line 130: Undefined index: email


I have tried testing the $_POST variable using the isset function but it apparently is set but empty. 

What would be a good way to test to see if the user has pressed the submit button before I go into the processing block that is intended to handle those values from the form?

Here is where my code is at right now:
Code: [Select]
if (!isset($_POST))
{
throw new Exception('You have not filled the form out completely - please go back'
.' and try again.');   
}
else
{
//filled in so create short variable names
$email=$_POST['email'];
$first_name=$_POST['first_name'];
$last_name=$_POST['last_name'];
