Showing the first element in an foreach array in HTML

Question

I have an array $category['transactions']. It stores data as follow:

ID   Name  Phone
1   Test   Test2
2   Test3  Test4

It's because I use the same array for different purpose, at one of the scenario is to show only the first record in this array. I don't what to change the coding in php nor creating a different parameter. What can I improve based on the following coding in html to get the first record only in this array?

                    <?php foreach($category['transactions'] as $transaction) { ?>
                            <div><?php echo $transaction['id']; ?></div>
                            <div><?php echo $transaction['name']; ?></div>
                    <?php } ?>

replace your code with.

<?php $firstRow=reset($category['transactions']);
    echo '<div>',$firstRow['id'],'</div>';
    echo '<div>',$firstRow['name'],'</div>';
?>

You don't need to iterate through the array to get the first element.

You don't even need the foreach to get the first element. Just use array_values():

$first = array_values($category['transactions')[0]

And you don't even need to copy the complete array, just use [`reset()`](http://www.php.net/reset). – Markus Malkusch Mar 05 '14 at 11:51
Interesting. I've never seen that before. Thanks. – Anonymous Mar 05 '14 at 11:53
I've added some html code. Would you please base on my example and tell where I should paste your code? – user2699714 Mar 05 '14 at 11:57
@user2699714 Try doing the anwser below. Which is the same thing that Markus Malkusch has said. – MONZTAAA Mar 05 '14 at 11:57
@user2699714 Just place the div tags right around `` and remove the foreach loop or put this before it. – Anonymous Mar 05 '14 at 11:59
@MONZTAAA ICIC. So how do I reset() based on my code? – user2699714 Mar 05 '14 at 12:01
@user2699714 As Anonymous mentioned just put the divs around the code. I edited my answer. – MONZTAAA Mar 05 '14 at 12:02
@user2699714 check my answer for reset solution. – bansi Mar 05 '14 at 12:03

try this..

<?php foreach($category['transactions'] as $transaction) { echo $transaction['id']; break; } ?>

and no need to use multiple php tags...
