How to loop php variables?

Question

I have a list of variables like this:

<?php 

$hh_1_date="Aug 29, 2012";
$hh_1_title="Data 1";
$hh_1_video="FFFnQGX0";
$hh_1_name="Peter Pan";
$hh_1_company="CompTIA";
$hh_1_image="image1.png";

$hh_1_date="Aug 30, 2012";
$hh_1_title="Data 2";
$hh_1_video="FFFRDEX0";
$hh_1_name="Peter Pooh";
$hh_1_company="CompTIA";
$hh_1_image="image2.png";

?>

And then I pull those variables into markup like this - all basic stuff...

  <div class="card">
    <img alt="..." class="card-img-top" src="<?php echo $hh_1_image?>">
    <div class="card-body">
      <span class="badge badge-pill badge-dark"><?php echo $hh_1_date ?></span>
      <h5 style="color:#0c0c0e"><?php echo $hh_1_title ?></h5>
    </div>
  </div>

But at the moment I am copying and pasting the above HTML and changing the PHP to _2 then _3 then _4 according to its respective PHP Variable which I know is the wrong way of doing it.

So, what is a faster way? I believe it's called looping?

Thanks

Fyi, you are overwriting your items in your "list of variables". An easier way would be to use arrays, which you can then loop over (using foreach) — user8034901

Using arrays is definitely the good choice. Meanwhile you can have a look at variable variables in the doc: php.net/manual/en/language.variables.variable.php — Zeitounator

Put all these variables in array with key value pair and use foreach loop, like this:

$arr =[
 [
'date' =>'Aug 30, 2012',
'title' => 'Data 1',
'video' => 'FFFRDEX0',
'name' => 'Peter Pooh',
'company' => 'CompTIA',
'image' => 'image1.png'
],
[
'date' =>'Aug 29, 2012',
'title' => 'Data 2',
'video' => 'FFFRDEX0',
'name' => 'Peter Pooh',
'company' => 'CompTIA',
'image' => 'image2.png'
]
....
.....
......
]

<?php foreach($arr as $k => $v): ?>
 <div class="card">
    <img alt="..." class="card-img-top" src="<?php echo $v['image']">
    <div class="card-body">
      <span class="badge badge-pill badge-dark"><?php echo $v['date'] ?></span>
      <h5 style="color:#0c0c0e"><?php echo $v['title'] ?></h5>
    </div>
  </div>
<?php endforeach; ?>

You can use the get_defined_vars (Here is the docs) function. Here is an example.

<?php 
$hh_1_date="Aug 29, 2012";
$hh_1_title="Data 1";
$hh_1_video="FFFnQGX0";
$hh_1_name="Peter Pan";
$hh_1_company="CompTIA";
$hh_1_image="image1.png";

$hh_1_date="Aug 30, 2012";
$hh_1_title="Data 2";
$hh_1_video="FFFRDEX0";
$hh_1_name="Peter Pooh";
$hh_1_company="CompTIA";
$hh_1_image="image2.png";

$vars = get_defined_vars();
foreach($vars as $key => $val){
    print_r($val);
}
?>

While iterating through, You'll get the variable name as key and variable's value as the value in a loop. Be careful, This method will also return the global variables defined by PHP(e.g $_SERVER, $_POST etc). The function get_defined_vars returns all the variables available in current scope along with it's value.
