Nested For Loop with the same iterator as the parent.
(Well formatted so the resulting code is clean when executed).
Useful for outputting a data array into a table, ie. images.
<?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";?>
