This is the array: http://www.stylechica.de/array.rtf (I can't copy it here)
I need to sum up ["PriceInformation"]["PriceInformation"]["PriceDetails"]["Price"] and allready tryed all kind of stuff like
foreach ($output["PriceInformation"]["PriceDetails"]["Price"] as $product)
echo array_sum($product);
but it just won't work. Any ideas?
Because $product refers to each iteration of $output["PriceInformation"]["PriceDetails"]["Price"], you can't sum the entire array like this. The best way to do it would be to add it to a variable as you go:
$your_sum = 0;
foreach($output as $value) {
$your_sum += $value['PriceInformation']['PriceDetails']['Price'];
}
echo 'Sum: ' . $your_sum;

I know this code to use in order to find the factorial of any number but what if we wanted it to do more and change up the code, so that it can calculate and print the factorials of number less that 100 recursively. How should this code be modified? Should i use for loop or some other technique?
Try this code, as suggested by LornaJane:
function factorial($number) {
if ($number < 2) {
return 1;
}
return ($number * factorial($number-1));
}

I have field in my table with data: DE;RO;US;
Question is how extract data in array as:
$array = array('DE', 'RO', 'US');
use explode function.
Like this :
$string = 'DE;RO;US;';
$arr = explode(';',$string);
You can use the function explode() here.
$array = explode(';', $data);
The variable data is the result of you database query.
http://us1.php.net/manual/en/function.explode.php
BTW: Your way to save things in the database is not good. Have a look at database normalization.

Could PHP check if a certain element in the array contains some words?
for example :
`[order_product_code] => I9300_cash397096569`
want to check if the element contains cash word.
If $array is your array of element:
foreach($array as $key=>$element) {
if(strpos('cash',$element) !== FALSE) echo "$key: ok";
else echo "$key: ko";
}

I am pulling out data from a table, but instead of breaking a line after each result(or set of results), I would like to break the line after 'x' amount of those results, so I don't get long pages.
How can this be done with PHP?
You haven't posted any code so your question is going to get marked as off-topic.
If you're trying to do line breaks every X number of iterations then just do it.
$i = 0;
while ($row1 = mysql_fetch_assoc($result1))
{
if ($i % 5==0) {echo '<div>Multiple of 5, line break here</div>';}
$i++;
}
You have to use a pagination. Use something like this http://stefangabos.ro/php-libraries/zebra-pagination/
