HTML table output using Nested for loops in PHP

By: Anonymous

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";?>
