How to print an entire PHP array in a single HTML cell? - php

Question

I have a HTML table where there are some columns. Each column is showing its own value. But in one cell of the table, I want to display an entire array of item-names separated by commas. I want the table cell to display like this:
User ID
Item Name
1
name1, name2, name3,....
$allitemnames holds the array values like name1, name2, name3 etc
This is my current code for fetching the array of items:
$itemnames="SELECT item_name FROM orderhistory WHERE uid='$userid' AND payment_mode = 'Cash'";
$itemnamescon=$con->query($itemnames);
$allitemnames=array();
while($x = mysqli_fetch_assoc($itemnamescon))
{
$allitemnames[]=array('item_name'=> $x['item_name']);
}
$itemsarrayresult = implode(", ", $allitemnames);
It's fetching the array properly because when I try to Echo out the $allitemnames outside the HTML table then it prints the whole array. But the main problem arises when i try to print it in a HTML table cell. I used the following code to print it:
echo"<tr style='color:white; background-color:#262626'>
<td><center>".$userid."</center></td>
<td><center>".$itemsarrayresult."</center></td>
</tr>";
This code does print multiple names in a single cell but the output is not at all what I want. It prints only "Array, Array, Array...."
Firstly it shows this warning message many times and it says-
Warning: Array to string conversion in C:\xampp\htdocs\Project\pendingpayments.php on line 62
and secondly the table looks like this:
User ID
Item Name
1
Array, Array, Array,....
I've had a look online but every forum I've come across has been people trying to loop through and print 1 value per td, not all values in one td

Answer 1

A couple of different approaches to this:
In php:
while($x = mysqli_fetch_assoc($itemnamescon))
{
$allitemnames[]=$x['item_name'];
}
$itemsarrayresult = implode(", ", $allitemnames);
In MySQL:
SELECT GROUP_CONCAT(item_name) FROM orderhistory WHERE uid='$userid' AND payment_mode = 'Cash'"

Answer 2

There is an multidimension array. You don't need her.
Do like this:
$allitemnames[] = $x['item_name'];

Answer 3

can you change your code as following and retry?
$itemsarrayresult = ''; //initialization
while($x = mysqli_fetch_assoc($itemnamescon))
{
$itemsarrayresult .= $x['item_name'].","; //concatenation
}
//now you need to display but variable will have an addirional ',' at the end so we will trim it using rtrim
echo '<tr style="color:white; background-color:#262626">
<td><center>'.$userid.'</center></td>
<td><center>'.rtrim($itemsarrayresult,',').'</center></td>
</tr>';
