I would like to use a foreach on an array and using the results from the first foreach to make the name of the array needed to do the next for each.

The array names for the second array can be $home_goalkeeprs, $home_defenders, $home_midfielders, $home_attackers.

My Code:

PHP Code:

$types = array('goalkeepers', 'defenders', 'midfielders', 'attackers');

// Player Rating Changes
foreach($types as $positions)
{
$positions = "$home_" . $positions . "";
foreach($positions as $key => $value)
{
$qry17='SELECT position, morale, condition FROM manager__players WHERE player_id = ' . $key. ' LIMIT 1';
$excQry17=mysql_query($qry17) or die("Could Not Execute Query 17!");
$excFet17=mysql_fetch_array($excQry17, MYSQL_NUM);
    if(in_array($excFet17[0], $positions))
    {    
    $rand = 100;
    } else {
    $rand = rand(70,90);
    }
$positions[$key] = round((((((($value / 100) * $excFet17[1]) / 100 * $excFet17[2]) * $tackling_style[$excFet1[1]] * $passing_style[$excFet1[2]] * $mentality[$excFet1[3]] * $tempo[$excFet1[4]]) / 100) * $rand), 0);
}
} 


Change all the $positions below (and including) the line

PHP Code:

foreach($positions as $key => $value) 


to $$positions

-->

PHP Code:

foreach($$positions as $key => $value)
{
$qry17='SELECT position, morale, condition FROM manager__players WHERE player_id = ' . $key. ' LIMIT 1';
$excQry17=mysql_query($qry17) or die("Could Not Execute Query 17!");
$excFet17=mysql_fetch_array($excQry17, MYSQL_NUM);
    if(in_array($excFet17[0], $$positions))
    {    
    $rand = 100;
    } else {
    $rand = rand(70,90);
    }
$$positions[$key] = round((((((($value / 100) * $excFet17[1]) / 100 * $excFet17[2]) * $tackling_style[$excFet1[1]] * $passing_style[$excFet1[2]] * $mentality[$excFet1[3]] * $tempo[$excFet1[4]]) / 100) * $rand), 0);
}
} 


Great works now. Thank you so much! Does making $$ tell it that its a variable???

Somewhat.
The $ actually tells PHP something like: what follows is a variable, so get it.
If you put two, it'll go like: what follows is a variable and the name of that variable is stored in a variable so fetch the variable named as that other variable.

The number of $'s you put could be infinite, I guess, but there's really no use to that. :P

One problem now it doesn't update the array $$positions2[$key] etc..

PHP Code:

// Player Rating Changes
foreach($types as $positions)
{
$positions2 = "home_" . $positions . "";
foreach($$positions2 as $key => $value)
{
echo $positions;
$qry17='SELECT position, morale, condition FROM manager__players WHERE player_id = ' . $key. ' LIMIT 1';
$excQry17=mysql_query($qry17) or die("Could Not Execute Query 17!");
$excFet17=mysql_fetch_array($excQry17, MYSQL_NUM);
    if(in_array($excFet17[0], $$positions))
    {    
    $rand = 100;
    } else {
    $rand = rand(70,90);
    }
$$positions2[$key] = round((((((($value / 100) * $excFet17[1]) / 100 * $excFet17[2]) * $tackling_style[$excFet1[1]] * $passing_style[$excFet1[2]] * $mentality[$excFet1[3]] * $tempo[$excFet1[4]]) / 100) * $rand), 0);
}
} 


When i echo the $$positions2[$key] in the for each i get the value but when i echo the main array like $home_defenders[0] it doesn't update that value.

Strange, because I can't see anything that could be wrong in your code.

When i echo $$positions2[$key] i get the new value;

if i print_r($$positions2) i get the old values!

But they don't go back into there old arrays $home_defenders etc....

I don't know how i can get it to work! any ideas???

Current Code:

PHP Code:

foreach($types as $positions)
{
$positions2 = "home_" . $positions . "";
foreach($$positions2 as $key => $value)
{
$qry17='SELECT position, morale, condition FROM manager__players WHERE player_id = ' . $key. ' LIMIT 1';
$excQry17=mysql_query($qry17) or die("Could Not Execute Query 17!");
$excFet17=mysql_fetch_array($excQry17, MYSQL_NUM);
    if(in_array($excFet17[0], $$positions))
    {    
    $rand = 100;
    } else {
    $rand = rand(70,90);
    }
$$positions2[$key] = round((((((($value / 100) * $excFet17[1]) / 100 * $excFet17[2]) * $tackling_style[$excFet1[1]] * $passing_style[$excFet1[2]] * $mentality[$excFet1[3]] * $tempo[$excFet1[4]]) / 100) * $rand), 0);
}
} 


Can anyone see why it doesn't work???

I think you should read up on "variable variables" and how they work.

Cheers sorted the problem all i had to do was ${$positions2}[$key] = ...!

I am glad that I read this post... I wasn't aware that you could dynamically create variables...

I will be using this in my future code....
