extracting database rows from an array within a foreach loop - php

Question

I am trying to extract 4 rows of product prices from a database table.
AU$ 11.00
AU$ 19.00
AU$ 32.00
AU$ 52.00
When i execute the code below i only retrieve the last value AU$ 52.00 from the database.
Array ( [CURRENCY] => AU$ 52.00 )
This is my code
$sql = DB::getInstance()->query('SELECT monthly FROM products');
foreach($sql->results() as $row) {
$price = '<small>AU$</small> ' . number_format($row->monthly, 2) . '<br>';
}
$currency = array(
'CURRENCY' => $price,
);
print_r($currency['CURRENCY']);
die();
?>
Probably overlooking somthing simple but my head is all bitter and twisted now. Any help will be useful. Thanks in advance
EDIT TO QUESTION
This will be a currency converter so the code below may help with how it will work
$currencies = array('AUD', 'USD', 'GBP', 'EUR', 'THB');
$get_cur = Input::get('currency');
if(isset($get_cur) === true && in_array($get_cur, $currencies) === true) {
$_SESSION['currency'] = $get_cur;
} else if (isset($_SESSION['currency']) === false) {
$_SESSION['currency'] = 'AUD';
}
include 'currency/' . $_SESSION['currency'] . '.php';
From each linked currency will go to AUD, USD, GBP etc etc
<a href="?currency=AUD">
Linked to AUD.php which is the code from the original question. This is why i need to link
$currency['CURRENCY']
This will be the defined name in the array of each currency.
Hope this helps
EDIT TO QUESTION #2
<?php
// Currency Covert Class
class CurrencyConverter {
public function convert($amount, $from, $to) {
$data = file_get_contents('https://www.google.com/finance/converter?a=' . $amount . '&from=' . $from . '&to=' . $to);
preg_match("/<span class=bld>(.*)<\/span>/", $data, $converted);
$converted = preg_replace("/[^0-9.]/", "", $converted[1]);
return $converted;
}

$currencies = array('AUD', 'USD', 'GBP', 'EUR', 'THB');
$get_lang = Input::get('currency');
if(isset($get_lang) === true && in_array($get_lang, $currencies) === true) {
$_SESSION['currency'] = $get_lang; //Get's the currency from whichever currency is selected from the $currencies = array('AUD', 'USD', 'GBP', 'EUR', 'THB');
} else if (isset($_SESSION['currency']) === false) {
$_SESSION['currency'] = 'AUD'; //If no currency selected, then default is AUD
}
include 'currency/' . $_SESSION['currency'] . '.php'; //Selects the currenct .php file eg; 'AUD', 'USD', 'GBP', 'EUR', 'THB'
//If AUD.php then it $_GET currency eg; ?currency=AUD, ?currency=USD, ?currency=GBP
// This is AUD.php (DEFAULT CURRENCY)
$sql = DB::getInstance()->query('SELECT monthly FROM products');
foreach($sql->results() as $row) {
$currency = array(
'CURRENCY' => '<small>AU$</small> ' . number_format($row->monthly, 2),
);
}
// This is USD.php
$converter = new CurrencyConverter;
$sql = DB::getInstance()->query('SELECT monthly FROM products');
foreach($sql->results() as $row) {
$currency = array(
'CURRENCY' => '<small>US$</small> ' . number_format($converter->convert($row->monthly, 'AUD', 'USD'), 2),
);
}
//So you can see that all the currency .php files have the key array word of 'CURRENCY', and this is how it will work from the $_SESSION['currency'] to the $currency['CURRENCY'] array
//Then simply echo out $currency['CURRENCY'] and it will convert to each $currencies = array('AUD', 'USD', 'GBP', 'EUR', 'THB');
echo '<p>' . $currency['CURRENCY'] . '<span>' . $lang['PER_MONTH'] . '</span></p>';
?>
EDIT TO QUESTION #3
I think i have found the issue, overlooked by me. It is inside a nested foreach loop
$sql = DB::getInstance()->query('SELECT * FROM products ORDER BY id ASC');
foreach($sql->results() as $row) {
if(escape($row->popular)) {
echo '<div class="col-md-3 price-table ' . escape($row->popular) . '">';
} else {
echo '<div class="col-md-3 price-table">';
}
?>
<h3><strong><?php echo escape($row->name) ?></strong><br><?php echo $lang['PACKAGE'] ?></h3>
<?php
///HERE IS WHERE IT GETS PULLED IN FROM AUD.php, USD.php, GBP.php, etc etc///
///START OF AUD.php///
$sql = DB::getInstance()->query('SELECT monthly FROM products');
$currency = array();
$currency['CURRENCY'] = array();
foreach($sql->results() as $row) {
array_push($currency['CURRENCY'], '<small>AU$</small> ' . number_format($row->monthly, 2));
}
///END OF AUD.php///
echo '<p>' . implode($currency['CURRENCY'], ' <span>' . $lang['PER_MONTH'] . '</span>') . '</p>';
The arrays is below
Array
(
[0] => AU$ 11.00
[1] => AU$ 19.00
[2] => AU$ 32.00
[3] => AU$ 52.00
)
I need it like this to be able to convert the currencies. So i need this;
echo '<p>' . implode($currency['CURRENCY'], ' <span>' . $lang['PER_MONTH'] . '</span>') . '</p>';
To echo out below in the first pass of the loop
echo '<p> AU$ 11.00 <span>Per Month</span></p>';
And echo out below in the second pass of the loop
echo '<p> AU$ 19.00 <span>Per Month</span></p>';
And so on. At the moment i am getting all four values on every pass of the loop

Answer 1

You arent adding the value in your loop so you only get the last value in $price
foreach($sql->results() as $row) {
$price = '<small>AU$</small> ' . number_format($row->monthly, 2) . '<br>';
$currency[]=array('CURRENCY' => $price);
}

Answer 2

Do this. it will do it perfectly
$sql = DB::getInstance()->query('SELECT monthly FROM products');
$currency = array();
$i=0;
foreach($sql->results() as $row) {
$price = '<small>AU$</small> ' . number_format($row->monthly, 2) . '<br>';
$currency['CURRENCY'][$i] = $price;
$i++;
}
print_r($currency['CURRENCY']);
?>

Answer 3

Do this:
$currency = array();
$currency['currency'] = array()
foreach($sql->results() as $row) {
array_push($currency['currency'], '<small>AU$</small> ' . number_format($row->monthly, 2));
}
echo '<p>' . implode($currency['CURRENCY'], ' <span>' . $lang['PER_MONTH'] . '</span><br />') . </p>';
Now foreach will push a value into the array $currency, with the correct currency.

Answer 4

Close foreach loop after you have assigned price to currency.
$currency = array();
foreach($sql->results() as $row) {
$price = '<small>AU$</small> ' . number_format($row->monthly, 2) . '<br>';
$currency[] = $price;
}
