Scroll through an array based on a 3 digit based variable

[lwc]

$array = array(5 => "001", 2 => "001001", 1 => "001001001", 9 => "002", 7 => "002001");

 

Each 3 digits mean a new level or sub level (e.g. XXX, XXXYYY, XXXYYYZZZ, etc.).

 

What I want is to have this printed:

<ul class="level">

<li>5</li>
<ul class="level">
<li>2</li>
<ul class="level">
<li>1</li>
</ul>
</ul>
<li>2
<ul class="level">
<li>7</il>
</ul>

</ul>

As <ul class="level"> adds another visual level, it should look something like:
*5
**2
***1
*9
**7

 

What do you think is the easier way to do it? Thanks!

You mean some think like this mate..

<?php

$array=array("123","123123","123123123","123","123123","123123123","123","123123","123123123");


$array[0]="level 1";


$array[3]="level 2";


$array[6]="level 3";


foreach($array as $key){

echo "<br>$key<br>";
}
?>

redarrow, do you ever bother trying your code before posting it?

 

<?php
$array = array(5 => "001", 2 => "001001", 1 => "001001001", 9 => "002", 7 => "002001");

foreach ($array as $key => $val) {
   $count = strlen($val) / 3;
   for ($x = 0; $x < $count; $x++) {
      echo "*";
   } // end for
   echo "$key<br/>";
} // end foreach
?>

 

That physically shows what you want, however if you were wanting to somehow separate the list, like when it goes from 001 to 002, you would have to throw in a condition on $val to add a new <br/> or <div> or whatever else you want to do to divide it.

Thanks! So in my case it would be:

 

$array = array(5 => "001", 2 => "001001", 1 => "001001001", 9 => "002", 7 => "002001");

foreach ($array as $key => $val) {
   $count = strlen($val) / 3;
   for ($x = 0; $x < $count; $x++) {
      echo "<ul class=\"advance level\">";
      if ($x == $count-1)
          echo "<li>";
   }
   echo "$key";
   for ($x = 0; $x < $count; $x++) {
     if (!$x)
        echo "</li>";
     echo "</ul>";
   } 
}
