php - converting swithch to .csv file read method - php

Question

Can someone please point me in the correct direction to convert my switch code from currently being listed like below to being drawn from a CSV file instead:
$video = (isset($_GET['video']) ? $_GET['video'] : null);
if($video) {
switch($video) {
case "apple":
$Heading ='Apple Heading';
$Videonum ='1';
$Content ='<h2>Apple Sub Heading</h2>
<p>Apple content</p>';
$SideContent ='Apple side content';
break;
I will end up with lots of cases and it'll be easier to manage from a .csv file - thank you

Answer 1

I think you need a two-dimensional array with the identifier ('apple', …) as the key for the inner arrays. By parsing a CSV-file you will get an array with multiple rows, but you need to search for the row, that contains the required data. Maybe you also can save PHP files containing the necessary data-arrays or even use a database (which is probably most common for such cases).
Target arrays as I would use it:
$data = array(
'apple' => array(
'heading' => 'Apple Heading',
'video_num' => 1,
'content' => '<h2>Apple Sub Heading</h2>
<p>Apple content</p>',
'side_content' => 'Apple side content',
),
/* more manufacturer sub-arrays */
);
In this first case you could access the whole data by just reading from the array:
if( !empty( $_GET['video'] ) && isset( $data[$_GET['video']] ) )
{
var_dump(
$data[$_GET['video']]['heading'],
$data[$_GET['video']]['content']
);
}
else
{
echo '<p class="error">No video specified or "' . $_GET['video'] . '" is not available.</p>';
}
FYI; Array as retrieved from a CSV-file:
$data = array(
1 => array(
'manufacturer' => 'Apple',
'heading' => 'Apple Heading',
'video_num' => 1,
'content' => '<h2>Apple Sub Heading</h2>
<p>Apple content</p>',
'side_content' => 'Apple side content',
),
/* more rows */
);

Answer 2

Read your csv file
$data = array();
$fp = fopen('manufacturer.csv', 'r');
while (!feof($fp)) {
$line = explode(';',fgets($fp));
$data[$line[0]]['heading'] = $line[1];
$data[$line[0]]['video'] = $line[2];
$data[$line[0]]['content'] = $line[3];
$data[$line[0]]['side'] = $line[4];
}
fclose($fp);
Your csv looks like
apple;Apple Heading;1;<h2>Apple Sub Heading</h2><p>Apple content</p>;Apple side content
microsoft;MS Heading;1;<h2>MS Sub Heading</h2><p>MS content</p>;MS side content
...
Then acces your content with the manufacturer name
if(isset($data[$_GET['video']] && !empty($_GET['video']))){
$Heading = $data[$_GET['video']]['heading'];
$Videonum = $data[$_GET['video']]['video'];
$Content = $data[$_GET['video']]['content'];
$SideContent = $data[$_GET['video']]['side'];
}
