Guys please show us some creativity, dont tell us you have completed a section but what you have learned out of that section by way of example.

Like i want to print out these stars.
*
**
***
****
*****
for ($i = 0; $i<5; $i++)
{
for ($x=0; $x<=$i; $x++)
{
echo '*';
}
echo '<br />';
}

Programming guys is awesome.

Completed this section.

Since there was no example for the do while, I will share a scenario where I have used it before. The do while loop can be very handy when reading text from a file. If you read the file one line at a time, you won't know when you have reached the end of the file unless you validate the input after reading the first line. Therefore you will execute the loop at least once to check if the input and then continue if it is not the end of the file. (The same functionality is sometimes used when communicating with socket servers)

I don't think you have to stress yourself flaunting your codes all around the forum Innocent. The forum is meant for posting questions, helpful links, sharing issues and resolving them. Cheers!

Learn to walk before you run.... these are advanced technologies! Rather keep to what we are studing at this point.

Arrays can be complicated, im currently working on three dimensional arrays, like this

Language: PHP
array = array(
                    array(';name';=>';innocent';, ';surname';=>';langa';, ';geography'; => array(';province';=>';kzn';, ';city';=>';durban';))
                    array(';name';=>';simo';, ';surname';=>';zaca';, ';geography'; => array(';province';=>';gauteng';, ';city';=>';sandton';));

Walking this array can really take sometime.

I've completed this section.

A mistake I have made before is to set the counter inside the loop, which results in the loop cycling 'forever' smiling smiley

I have to remind myself now to:
(1) always create the counter variable outside of the loop!
(2) to make 100% certain that the loop will always complete – by not resetting the variable unwittingly each time around the loop and by making sure that the condition for keeping the loop running will without a doubt at some point be false and kick out of the loop.

Hi, referring to H, Malatji. For me at the moment is remembering the codes, as I am learning new things in the sea rescue as well, I've gotten myself confused with some of the coding in the for loop. but I will definitely rise to ask should I get stuck.
Regards smile

For a times table that goes backwards & forwards, and to keep the values entered in the text fields - here's some code:

Language: PHP
<head>
    <title>A Times Table Programme</title>
 
    <?PHP
    	$times = 2;
    	$keepstart = 1;
    	$keepend = 10;
 
        if (isset($_POST[';Submit1';])) {
            $keepstart = $start = $_POST[';txtStart';];
            $keepend = $end = $_POST[';txtEnd';];
            $times = $_POST[';txtTimes';];
 
            if($start <= $end){
               for($start; $start <= $end; $start++) {
                  $answer = $start * $times;
                   print $start . " multiplied by " . $times . " = " . $answer . "<br />";
    	       }
    	    }
            else {
               for($start; $start >= $end; $start--) {
                  $answer = $start * $times;
                  print $start . " multiplied by " . $times . " = " . $answer . "<br />";
    	       }
            }
    	    print "<p></p>";
         }
    ?>
 
</head>
 
<body>
 
      <FORM NAME = frmOne Method = "POST" Action = "timesTable.php">
          Start Number: <INPUT TYPE = Text NAME  = txtStart SIZE = 5 value = <?PHP print $keepstart; ?> >
          End Number: <INPUT TYPE = Text NAME = txtEnd SIZE = 5 value = <?PHP print $keepend; ?> >
          Multiply By: <INPUT TYPE = Text NAME = txtTimes SIZE = 5 value = <?PHP print $times; ?> >
          <p></p>
          <INPUT TYPE = Submit Name = Submit1 VALUE = "Do Times Table">
          <p></p>
      </FORM>
</body>
