HTML table output using Nested for loops in PHP

By: Anonymous in PHP Tutorials on 2012年04月05日 [フレーム]

Nest for loops are used for handling many difficult situations such as Matrix, Recursion etc..In this example, it is shown how nested for loops are useful for outputting a data array into a table (ie. images). Additionally in this example, the Nested For Loop uses the same iterator as the parent for loop. Well formatted so the resulting code is clean when executed.

<?php
//Dummy data
$data = array(73,74,75,76,78,79,80,81,82,83,84,85,86,87);
//Our 'stepping' variable
$g = 0;
//Our rowcount
$rowcount = 0;
echo "<table cellspacing='0'>\r";
 for ($i=0; $i<count($data); ) {
 $rowcount++;
 echo " <tr>\r"; //New row
 $g = $i + 3; //Set our nested limit
 for( ; $i<$g; $i++) { //nested for loop
 if (!isset($data[$i])) { //Allow us to break on incomplete rows
 break;
 }
 echo " <td style='border: 1px #000 solid;'>\r"; //Out put a cell
 echo " <p>Row $rowcount <br/> Cell: $i <br/> Data: $data[$i]</p>\r";
 echo " </td>\r";
 }
 echo " </tr> \r"; //End New Row
 }
echo "</table>\r";
?>
