<details> <summary> php code tutorial example: How to retrieve nested master => detail records per php and mysql – Photoshop

based on Master => Detail relations of mysql fields in a database:

Company – Program – Level

  • Adobe – Photoshop – Beginner
  • Adobe – Photoshop – Advanced
  • Adobe – Illustrator – ….
  • ….
  • Microsoft – Word – Beginner
  • ….
  • Microsoft – Excel – ….

I am struggling with the multi-level – layouts, also called nested , in HTML5 only without JavaScript.

I want to use an sql String with "Select field1,field2,field3" to display the contents like in a windows-Explorer style.

Perhaps there is a tutorial / Excample out there? so far I have not found a multi-level php script using HTML 5 only without the use of JavaScript!

    This is my answer how to create a combination of entries in a three arrays.

        <?php
function combinations($arrays, $i = 0) {
    if (!isset($arrays[$i])) {
        return array();
    }
    if ($i == count($arrays) - 1) {
        return $arrays[$i];
    }
    // get combinations from subsequent arrays
    $tmp = combinations($arrays, $i + 1);
    $result = array();
    // concat each array from tmp with each element from $arrays[$i]
    foreach ($arrays[$i] as $v) {
        foreach ($tmp as $t) {
            $result[] = is_array($t) ? 
                array_merge(array($v), $t) :
                array($v, $t);
        }
    }
    return $result;
}
$arrCombi=combinations(
    array(
        array('Microsoft','Adobe','Softskills'), 
        array('Word','Excel','Photoshop','Homeoffice'), 
        array('Grundlagen','Expert')
        )
    );
$line="";
foreach ($arrCombi as $k => $v){
    $line .= "(".implode(" AND ",$v) . ")  OR n";
}
$line=substr($line, 0, -4);
echo nl2br($line);
echo"<hr><pre>";
print_r(
    combinations(
        array(
            array('Microsoft','Adobe','Softskills'), 
            array('Word','Excel','Photoshop','Homeoffice'), 
            array('Grundlagen','Expert')
        )
    )
);
echo "</pre>";
?>
