Question

I am pulling some data from a mysql table via the following:

$result = mysql_query("SELECT characters_ID, name, borndate, deathdate, marrieddate, ispregnant FROM characters WHERE isfemale='1'",$db);
$femaledata = array();

while ($row_user = mysql_fetch_assoc($result))
$femaledata[] = $row_user;

This gives me an array that looks like this:

Array ( 
    [0] => Array ( [characters_ID] => 2 [name] => Helene [borndate] => 35 [deathdate] => 431 [marrieddate] => 157 [ispregnant] => 0 ) 
    [1] => Array ( [characters_ID] => 4 [name] => Isabelle [borndate] => 161 [deathdate] => [marrieddate] => 303 [ispregnant] => 1 ) 
    [2] => Array ( [characters_ID] => 7 [name] => Helene [borndate] => 326 [deathdate] => [marrieddate] => [ispregnant] => 0 ) 
    [3] => Array ( [characters_ID] => 72 [name] => Faylinn [borndate] => 335 [deathdate] => [marrieddate] => [ispregnant] => 0 ) 
    [4] => Array ( [characters_ID] => 74 [name] => Relina [borndate] => 349 [deathdate] => [marrieddate] => [ispregnant] => 0 ) 
    )

Now I need to remove any characters who have a value for deathdate or ispregnant, and then I need to run some code on the others. For instance I need to grab the borndate value, compare it to the current date to find age, and based partly on age, I need to run code for each to determine if the character has become pregnant on the turn.

Apologies that this seems like a long-reaching question. Multidimensional arrays still seem to confound me.

Edit: (question needs to be more clear)

Can you please suggest the best way that I would either explode or break up the array, and then do conditional modification to the data, or instead how I could remove unneeded data and then do conditional modification to the data.

My ultimate output here would be taking suitable female characters (not dead or pregnant already), and based on their age, giving them a chance at becoming pregnant. If true, I’d throw some code back at the SQL database to update that character.

Thanks!

Instead if immediately removing some rows from your array, try limiting the data you recieve through SQL.

You can loop through your array like this:

foreach($femaledata as $female)
{
 echo $female['name'];
}
