Question

I am trying to build a simple page that will show book information, I was going to store it all in a database but I have decided it would be better to just build a multidimensional array and store it in that.

There is just 4 “books” in the example below but there could be up to 100 eventually.

I need help iterating over this array and showing each item in an HTML <li> but I need to only show 4 in a row then start a new row. Can someone show me how to accomplish this?

<?php
$books = array(
        1 => array(
            'name' => 'book 1 name here',
            'url' => '',
            'big_photo' => 'big photo of book 1',
            'small_photo' => 'small photo of book 1',
            'bio' => 'short bio 1'
            ),
        2 => array(
            'name' => 'book 2 name here',
            'url' => '',
            'big_photo' => 'big photo of book 2',
            'small_photo' => 'small photo of book 2',
            'bio' => 'short bio 2'
            ),
        3 => array(
            'name' => 'book 3 name here',
            'url' => '',
            'big_photo' => 'big photo of book  3',
            'small_photo' => 'small photo of book 3',
            'bio' => 'short bio 3'
            ),
        4 => array(
            'name' => 'book 4 name here',
            'url' => '',
            'big_photo' => 'big photo of book 4',
            'small_photo' => 'small photo of book 4',
            'bio' => 'short bio 4'
            )
);

echo $books["1"]["small_photo"];
?>

Example output

<ul>
    <li>books data</li>
    <li>books data</li>
    <li>books data</li>
    <li class="lastRow">books data</li>
    <li>books data</li>
    <li>books data</li>
    <li>books data</li>
    <li class="lastRow">books data</li>
    <li>books data</li>
    <li>books data</li>
    <li>books data</li>
    <li class="lastRow">books data</li>
</ul>

<?php

$perRow=4;
$i = 0;
foreach($books as $book){
    if($i === 0){
        echo '<div class="row">';
    }
        echo '<div>';
        echo $book['name']. '<br>';
        echo $book['url']. '<br>';
        echo $book['big_photo']. '<br>';
        echo $book['small_photo']. '<br>';
        echo $book['bio']. '<br><br><br>';
        echo '</div>';

    if($i === $perRow){
        $i = 0;
        echo '</div>';
    }else{
        $i++;
    }
}

?>
