How to display the HTML which is the inside foreach if the array is empty?-CodePudding

I have the below code on my page and it's working when there is any data in the $getbanking variable. But if $getbanking is empty then I am getting the error

Warning : Invalid argument supplied for foreach() in

I have to run the below code if there $getbanking is empty at least once. So that it will display the upload option to the user.

<?php 
  $getbanking = unserialize($info['banking_details']); 

  $i=1;
  foreach ($getbanking as $bankdoc => $b) {   ?>
<div >
  <div >
    <label>Bank <?php   echo $i;   ?></label>
    <div  imgext uploaded "; }   ?>">
      <input type="hidden" name="banking[<?php   echo $bankdoc;   ?>]" value="<?php   echo $b;   ?>">
      <input type="file" name="banking[<?php   echo $bankdoc;   ?>]"  accept="image/png, image/jpeg, application/pdf, .doc,.docx,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document">
      <div >
        <div ></div>
        <p>Drop your image here, or <span>browse</span></p>
        <span>Supports: JPEG, PNG, DOC, PDF</span>
      </div>
      <div >
        <a href="uploads/<?php   echo $b;   ?>" target="_blank">
          <div ></div>
        </a>

        <p ><?php   echo $b;   ?></p>
      </div>
      <?php   if($i>=2) {   ?>
      <div ><img src="assets/images/x-circle.svg"></div>
      <?php   }   ?>
    </div>
  </div>
</div>
<?php   $i  ; }   ?>

You can do something like ---

<?php 
  $getbanking = unserialize($info['banking_details']); 
if(!empty($getbanking)){
  $i=1;
  foreach ($getbanking as $bankdoc => $b) { ?>
<div >
  <div >
    <label>Bank <?php echo $i;?></label>
    <div  imgext uploaded ";} ?>">
    <input type="hidden" name="banking[<?php echo $bankdoc;?>]" value="<?php echo $b;?>">
      <input type="file" name="banking[<?php echo $bankdoc;?>]"  accept="image/png, image/jpeg, application/pdf, .doc,.docx,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document">
      <div >
        <div ></div>
        <p>Drop your image here, or <span>browse</span></p>
        <span>Supports: JPEG, PNG, DOC, PDF</span>
      </div>
      <div >
        <a href="uploads/<?php echo $b;  ?>" target="_blank">
          <div ></div>
        </a>

        <p ><?php echo $b;  ?></p>

      </div>
      <?php if($i>=2){?>
      <div ><img src="assets/images/x-circle.svg"></div>
      <?php }?>
    </div>
  </div>
</div>
<?php $i  ; }
}else{
///you can write a div here to show no information or something
} ?>

You could do something like this, so that if $getbanking is empty, we populate it with an empty row, but I have no idea if blank values will work with your upload process

$getbanking = unserialize($info['banking_details']);

if (empty($getbanking)) {
    $getbanking = [0 => ''];
}
