Hi,

 

I am working to an exercise and I have a little problem.

 

Make a script that populates a PHP array of 10 times 10 cells. The value in each cell must be the array indexes referencing that cell, multiplied together. e.g. 7*4 = 28 and 0*9=0. Hint: Make you script use e.g. a while loop inside a while loop to fill the array.

 

Now write a second script part, in the same script file, that makes the PHP array being printed in a nice formatted way. For example by using HTML table tags. Again make the script use some kind of loop inside a loop to print the table and take out the values from the array.

 

I make the first part and almost I finish the second but I have some problem with that, I don t understand so well how this suppose to work.

This suppose to be the final result: http://zuscience.com/php.png

 

This is the code almost finish but I don t understand how to fix the last part to make it work.

 

 

<?php

//File array section

$yStart = 0;
$y = $yStart;

while( $y < (10 + $yStart)) {
   $x = 0;
   while ( $x < 10) {
       $myArray[$x][$y] = $x * $y; //array entry
       $x++;
       }
   $y++;
   }

//Print Section

$x = 0;

echo '<table border="1">';
echo '<tr>';                      //print vertical index row
echo '<td>'; echo 'Index'; echo '<td>';

while ( $x < 10 ){
   $x++;
   }
echo '</tr>';

$y = 0;

   while ( $y < 10 ) {
   echo '<col with= "30">';
   $x = 0;
   echo '<tr><td>' . $y . '</td>';  //print horisontal
   index

   while ( $x < 10) {
   echo '</td>'   $myArray[$x][$y];    //cell content
   $x++;
   }
   echo '</tr>'
   $y++;

   }

?>  

 

Some sugestions what I am doing wrong? :happy-04:

A bunch of syntax errors on that code :(

 


<?php

$rows = range(0, 9);
$cols = range(0, 9);

echo "<table border='1' cellpadding='10'cellspacing='5' align='center'>";

$r = 0;
while ($r < count($rows)) {

$c = 0;
echo "<tr> ";
while ($c < count($cols)) {
 echo "<td>";
 echo $rows[$r] * $cols[$c];
 echo "</td>";
 $c++;
}
echo "</tr>";
$r++;
}

echo '</table>';
