PHP - Call A Function Within A Foreach Loop

I've made this code for a very simple registration form practice:

 

  //assign form variables
  $firstname = $_POST['firstname'];
  $lastname = $_POST['lastname'];
  $username = $_POST['username'];

  function clean_names($dirty_name) {
      strip_tags($dirty_name);
      str_replace(' ', '', $dirty_name);
      ucfirst(strtolower($dirty_name));

      //return $dirty_name;
    }

  $names = array($firstname, $lastname, $username);

  if(isset($_POST['register_button'])) {

    //  WHY IS THIS FUNC CALL NOT WORKING??
    foreach($names as $name) {
      clean_names($name);

    }

    echo "First Name: " . $firstname . "<br>";
    echo "Last Name: " . $lastname . "<br>";
    echo "Username: " . $username . "<br>";

  }

The values are returned but they haven't been put through the clean_names function.
I'm really new with PHP. Can someone tell me why this isn't working? Thank you

ok.

say i have a list with a foreach loop in it.
like this:

Code: [Select]
echo'
<ul>';

$link = Link::find_all();
foreach($link as $links){
$name = $links->name;

echo'
<li>'.$name.'</li>';

}
echo'
</ul>';




now.
say that i want to put this part :
Code: [Select]
$link = Link::find_all();
foreach($link as $links){
$name = $links->name;

into a function so i can reuse the code...

like this:

FUNCTION
Code: [Select]
function(find_li){
  $link = Link::find_all();
  foreach($link as $links){
  $name = $links->name;
}
Code: [Select]
echo'
<ul>';

find_li();

echo'
<li>'.$name.'</li>';
}
echo'
</ul>';


the problem is the foreach } its not inside the function so the function will not work. but it needs to be after the </li> so that i get all the results in the <li>

so is there a way to put the function before the <li> and the } after the </li>

Below is my output on the browser:

    Student: Kevin Smith (u0867587)
    Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
    Year: 3
   
   
    Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B
   
    Session: AAB Session Mark: 72 Session Weight Contribution 20%
   
    Session: AAE Session Mark: 67 Session Weight Contribution 40%


    Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B
   
    Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.
   
    Below is the code:

Code: [Select]
    $sessionMark = 0;
    $sessionWeight = 0;
    $courseMark = 0;
   
    $output = "";
   
    $studentId = false;
    $courseId  = false;
    $moduleId  = false;
   
    while ($row = mysql_fetch_array($result))
    {
   
   
    $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
    $sessionWeight  += ($row['SessionWeight']);
        $courseMark = ($sessionMark /  $sessionWeight * 100);
   
          if($studentId != $row['StudentUsername'])
        {
   
            //Student has changed
            $studentId = $row['StudentUsername'];
   
            $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";
   
        }
             
        if($courseId != $row['CourseId'])
        {
   
            //Course has changed
            $courseId = $row['CourseId'];
   
            $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong>  <br><strong>Year:</strong> {$row['Year']}</p>\n";
   
        }
   
        if($moduleId != $row['ModuleId'])
        {
   
            //Module has changed
            if(isset($sessionsAry)) //Don't run function for first record
            {
   
                //Get output for last module and sessions
                $output .= outputModule($moduleId, $moduleName, $sessionsAry);
            }
   
            //Reset sessions data array and Set values for new module
   
            $sessionsAry = array();
            $moduleId    = $row['ModuleId'];
            $moduleName  = $row['ModuleName'];
        }
             
        //Add session data to array for current module
             
        $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);
             
    }    //Get output for last module
   
    $output .= outputModule($moduleId, $moduleName, $sessionsAry);
   
    //Display the output
    echo $output;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?

I can call the following function successfully as a single php program

  // Acknowledge and clear the orders
   function ack($client, $merchant, $id) {
         $docs = array('string' => $id);
         $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs);
         $result = $client->call('postDocumentDownloadAck', $params);
         return $result;
         }
with

   $result = ack($t, $merchant,'2779540483');

successful output

    [documentDownloadAckProcessingStatus] => _SUCCESSFUL_
    [documentID] => 2779540483

I'm trying to figure out how to call this function as an object from another program.

Trying the following gives error  ***Call to a member function call() on a non-object***

  function postDocumentDownloadAck($t, $merchant, $id) {
     $this->error = null;
     $docs = array('string' => $this->id);
     $params = array('merchant' => $this->merchant, 'documentIdentifierArray' => $docs);

 **  I've tried the following which does nothing
     $result = $this->soap->call('postDocumentDownloadAck', $params);

** I've tried the following   -  which gives error "Call to a member function call() on a non-object"
     $result = $this->t->soap->call('postDocumentDownloadAck', $params);

     if($this->soap->fault) {
        $this->error = $result;
        return false;
     }

     return $result;
  }


***

calling program snippet for above function
   $merchant= array( "merchant"=> $merchantid, "merchantName" => $merchantname, "email"=> $login, "password"=> $password);
   $t = new AmazonMerchantAPI($merchantid, $merchantname, $login, $password);
   $documentlist= $t->GetAllPendingDocumentInfo('_GET_ORDERS_DATA_');
   $docid = $documentlist['MerchantDocumentInfo'][$i]['documentID'];
   $docs = array('string' => $docid);
   $ackorders = $t->postDocumentDownloadAck($t, $merchant,$docs);

Any ideas of what I'm doing wrong are greatly appreciated.
