Question

Hi there i’ve 2 fields in a mysql database with similar content:

Field 1: a>b>c
Field 2: 1>2>3

I wish to put them in different rows, exploded.

Example:

-----------------
|Field 1|Field 2|      
|----------------
|a      |1      |
|b      |2      |
|c      |3      |

Here a snippet for the code that should make the work:

$result = mysql_query($insert_cat);
while ($row = mysql_fetch_assoc($result))
{
    //assegno variabili per l'array associativo
    $idcat = $row["id_categorie"];
    $descat = $row["categoria"];

    //inizio a ciclare all'interno degli array per ricavare le categorie
    $ar_id=explode('>',$idcat);
    $ar_des=explode('>',$descat);

    foreach($ar_id as $value_id)
    {

        foreach($ar_des as $value_des)
        {

        }

        echo $value_id.'|'.$value_des."\n";
    }
}

The problem is: how can I (for testing) echoing what should be inserted in the table?
I’ve tried but with no luck.

Have you tried using the array_combine function – see the php docs on the subject.

This will merge two arrays, with the first as they keys for the second. As a result you can replace your foreach loops with something like this

$fullArray = array_combine($ar_id, $ar_des);
foreach($fullArray as $key_id => $val_des)
{
    echo $key_id . " | " . $val_des;
}
