Php, printing a 3d array into a table - php

Question

Basically i need to sort some data into the top 5 best sales.
I've managed to group the 3 arrays i've used using.
$c = array_combine($PriceArray,$namesArray,$ProductArray);
krsort($c);
Price array being the total. (Bit of a silly name, i just realised)
namesarray is the array of names
and product array is the list of product codes
I need to print it in a table like
"|£3.45|Jelly Beans | 120|"
so they have their own column, but at the moment it's printing it like
| 3.45| array | array|
and i use
echo '<td>'.$ProductArray[$i].'</td>'.'<td>'.$year.'</td>'.'<td>'.array_keys($c,$c[$i]).'<td>'. $PriceArray[$i].'</td>';
to print it.
Thanks in advance

Zip function blatantly stolen from: zip function from SO
function zip() {
$args = func_get_args();
$zipped = array();
$n = count($args);
for ($i=0; $i<$n; ++$i) {
reset($args[$i]);
}
while ($n) {
$tmp = array();
for ($i=0; $i<$n; ++$i) {
if (key($args[$i]) === null) {
break 2;
}
$tmp[] = current($args[$i]);
next($args[$i]);
}
$zipped[] = $tmp;
}
return $zipped;
}
function cmp($a, $b)
{
if($a[0] == $b[0]){
return 0;
}
return ($a[0] < $b[0]) ? -1 : 1;
}
$PriceArray = array( 4.56, 1.23, 7.89 );
$namesArray = array( 'ab', 'cd', 'ef' );
$ProductArray = array( '11', '22', '33' );
$c = zip($PriceArray, $namesArray, $ProductArray);
usort($c, 'cmp');
foreach($c as $prices)
{
//$prices[0] == price
//$prices[1] == name
//$prices[2] == code
echo "{$prices[0]}|{$prices[1]}|{$prices[2]}\n";
prints:
1.23|cd|22
4.56|ab|11
7.89|ef|33
I am using the zip-function that is available natively in Python to combine N-arrays and "zip" them together.
So take index 0 of all given arrays, and make that a new array entry. Do that for all indices available.
The cmp function takes two variables, in this case two arrays, where index-0 = price, 1 = name and 2 = code. You obviously want to sort by ascending by price thus we are comparing the price index. This results in a new/sorted array based on price.
You can also substitude the usort($c, 'cmp'); call with the following:
usort($c, function($a, $b){
if($a[0] == $b[0]){
return 0;
}
return ($a[0] < $b[0]) ? -1 : 1;
});
However, this is only available in PHP version >= 5.3

Just put the keys and values into new arrays.
$NewNamesArray = array_values($c); $NewPriceArray = array_keys($c)
