from "1_2_3" to "1, 1_2, 1_2_3"

[stacyr]

hello!

 

anyone know how you convert the string:

$currentcategory = "category1_sub1_sub2_sub3"

 

to this:

$categorytree = "category1.php : category1_sub1.php : category1_sub1_sub2.php : category1_sub1_sub2_sub3.php"

 

?

 

i.e. how could you go from "1_2_3" to "1 - 1_2 - 1_2_3" ?

try

<?php
$str = '1_2_3_4';
$a = explode ('_', $str);
$b = array();
for ($i=1, $k=count($a); $i <= $k; $i++)
{
    $b[] = join('_', array_slice($a, 0, $i));
}
echo join(' : ', $b);
?>

try

<?php
$currentcategory = 'category1_sub1_sub2_sub3';
$currentcategory =explode('_', $currentcategory);
for($i = 1; $i < count($currentcategory); $i++) $currentcategory[$i] = $currentcategory[$i - 1].'_'.$currentcategory[$i];
$categorytree =implode('.php : ', $currentcategory).'.php';
echo $categorytree;
?>
