Limit display to 10 in foreach statement PHP - php

Question

I have an API that's showing almost 100 trades that I want to limit to just 10. I've tried
if($bitcointrades == 10) break
but that didn't work. Do I run a for loop after I pull the data? Should I break up the functions into two parts as opposed to using elseif to present $trades? Here's what I'm working with:
<?php
require_once('bitcoin.class.php');
$data = new Bitcoin();
$type = $_GET['type'];
$currency = $_GET['currency'];
if($type == 'ticker') {
$bitcoinlive = $data->getPrice($currency);
echo '<h2>1 Bitcoin is currently worth <span class="bitvalue">' .
number_format((float)$bitcoinlive['last'], 2) . ' <span class="upper">'
. $currency . '</span></span></h2>';
echo ' <p><span><i class="icon-arrow-up-circle"></i> High: ' .
number_format((float)$bitcoinlive['high'], 2) . '</span> <span><i
class="icon-arrow-down-circle"></i> Low: ' .
number_format((float)$bitcoinlive['low'], 2) . '</span>';
} elseif($type == 'trades') {
$bitcointrades = $data->getTrades($currency);
foreach($bitcointrades as $trade) {
if($trade['type'] == 'buy') {
$ttype = '<span class="green"><i class="icon-plus-circle"></i> Buy
Order</span>';
} else {
$ttype = '<span class="blue"><i class="icon-circle-minus"></i> Sell
Order</span>';
}
echo' <tr> <th scope="row">' . $ttype . '</th> <td>' . $trade['price']
. ' <span class="upper">' . $currency . '</span></td> <td>' .
$trade['amount'] . '</td> <td>' . $data->timeAgo($trade['date']) .
'</td> </tr>';
}
}

Answer 1

It's normal if($bitcointrades == 10) break isn't going to work.
$bitcointrades should be an array with trades which you define as $trade.
You need to use an iterator i like in the example below:
<?php
$i = 0;
foreach($bitcointrades as $trade) {
if($i==10)
break;
// your logic here
$i++;
}

Answer 2

You can finish a foreach execution using break so you can use a cnt and break
$my_cnt = 0;
foreach($bitcointrades as $trade) {
if ($my_cnt >= 10) {
break;
}
if($trade['type'] == 'buy') {
$ttype = '<span class="green"><i class="icon-plus-circle"></i> Buy
Order</span>';
} else {
$ttype = '<span class="blue"><i class="icon-circle-minus"></i> Sell
Order</span>';
}
$my_cnt++;
}

Answer 3

Do Like this way
$i = 0;
foreach ($bitcointrades as $trade) {
if ($trade['type'] == 'buy') {
$ttype = '<span class="green"><i class="icon-plus-circle"></i> Buy Order</span>';
} else {
$ttype = '<span class="blue"><i class="icon-circle-minus"></i> Sell Order</span>';
}
echo ' <tr> <th scope="row">' . $ttype . '</th> <td>' . $trade['price']
. ' <span class="upper">' . $currency . '</span></td> <td>' .
$trade['amount'] . '</td> <td>' . $data->timeAgo($trade['date']) .
'</td> </tr>';
$i++;
if ($i == 10) {
break;
}
}
