Answer 1

can you give more info regarding the source of this text you want to format? it seems like Contenu and Prepresse Fichier are both names for a group

where you have items like 2 encarts , 12 encarts and fourni as items in those groups

The first thing is to detect if the text is a group name or an item, I hope this can be detected from the source where your text comes from. The second thing is echoing the items correctly.

EDIT:

I do a lot using arrays, created your output using this code:

$text = "Contenu\n\t2 encarts\n\t12 encarts\n\nPrepresse\n\tFichier fourni";

//divide the groups
$groups = explode("\n\n", $text);

//loop groups
foreach ($groups as $group) {

    //get group name and items
    $items = explode("\n\t", $group);

    //loop items, 
    foreach ($items as $item => $value) {
        switch ($item) {
            case 0: 
                //first item is group name
                echo $value . " ";
                //get the length of this group name to align all items using spaces
                $length = strlen($value) + 1;
                break;
            case 1: //second item is first value, what apears next to the group name
                echo $value . "<br>";
                break;
            default: // other items, where the spaces are the length of the groupname
                echo str_repeat("&nbsp;", $length) . $value . "<br>";
                break;
        }
    }

    //when an entire group is shown, leave an empty space
    echo "<br>";

}

?>

shows me this as output:

Contenu 2 encarts
        12 encarts

Prepresse Fichier fourni

hope this helps

Answer 2

Using regexps can be done as:

<?php
$text = "Contenu\n\t2 encarts\n\t12 encarts\n\nPrepresse\n\tFichier fourni";    
echo $text."\n";    
echo preg_replace('/((^.+)(\n\t))/ime', "str_replace('$3', ' ', '$0')", $text);
?>

output of this is:

Contenu
    2 encarts
    12 encarts

Prepresse
    Fichier fourni
Contenu 2 encarts
    12 encarts

Prepresse Fichier fourni
