Getting from database to make one row

I would take the easy way out here.  

SELECT {column names} FROM my_table

Retrieve the rows into an array.  Count the rows with PHP.  Collapse the field you need into an array and reformat it with implode().  

I'll try to give you a code sample in a moment.

If you're new to PHP and want to find some learning resources, this article might help.

Adapt to your code

// Create our result array
$rollup = array();
$conn = new mysqli('localhost','user','password','databse');
// Error checking for DB connect
// Get the rows from the db
$query = "SELECT id, insurance FROM thetable";
$result = $conn->query($query);

// We got rows ...
if ($result) {
  // Loop through results
  while($row = $result->fetch_object()) { 
    // Is this the first time we have seen this ID - if so make an entry for it
    if (empty($rollup[$row->id])) {
      $rollup[$row->id] = array(
        'insurance' => $row->insurance, 
        'rows' => 1
      );
    }
    // Otherwise add to existing and bump row count
    else {
      $rollup[$row->id]['insurance'] .= ",{$row->insurance}";
      $rollup[$row->id]['rows']++;
    }
  }
}
// Dump the results
echo "<pre>" . print_r($rollup,true) . "</pre>";

Select allOpen in new window

Sample output

Array
(
    [22] => Array
        (
            [insurance] => UH,AA,EI,AC
            [rows] => 4
        )

    [12] => Array
        (
            [insurance] => AA,AA
            [rows] => 2
        )

    [14] => Array
        (
            [insurance] => EI,GH
            [rows] => 2
        )

    [23] => Array
        (
            [insurance] => AB
            [rows] => 1
        )

    [25] => Array
        (
            [insurance] => DC
            [rows] => 1
        )

    [11] => Array
        (
            [insurance] => AA,AT
            [rows] => 2
        )

)

Select allOpen in new window

To get the output you wanted

echo "<pre>" . print_r($rollup,true) . "</pre>";
echo "<pre>";
foreach($rollup as $k => $v) {
   $rows = $v['rows'] > 1 ? 'rows' : 'row';
    echo "{$k}  {$v['rows']} {$rows} {$v['insurance']}\n";
}
echo "</pre>";

Select allOpen in new window

Output

22  4 rows UH,AA,EI,AC
12  2 rows AA,AA
14  2 rows EI,GH
23  1 row AB
25  1 row DC
11  2 rows AA,AT

Im using PostgreSQL  is it the same?

Please see https://iconoun.com/demo/temp_jasmine_8.php

A couple of cautionary notes.  The use of "id" to identify anything other than the auto_increment primary key is likely to be confusing.  I used it here because you used it in the question, but in "real life" you do not want to do that.  Change the column name.

Make a Google search for the exact phrase "Should I Normalize My Database" and read the very interesting comments on both sides of the issue.

This script is mostly setup.  Hopefully the comments will help!  The demonstration starts on line 125.

I have this so far what can I add to get the output I need/?

<?php 
error_reporting(E_ALL);
ini_set('display_errors' ,1);
require "connection.php";


$query= "SELECT * from vouchers WHERE parsing_date=CURRENT_DATE ";
$result = pg_query($conn,$query);



?>
  <?php 
  	while($row = pg_fetch_array($result))
	{ 


  ?>
  
  <tbody>


     <td><?php echo $row['client_id']; ?></td>

     <td><?php echo $row['insurance']; ?></td> 
     <td><?php echo $row['parsing_date']; ?></td>
    
    
    </tr>
  <?php  }?>  </tbody>

Select allOpen in new window

This gives me 3 rows: client id, insurance and date , However I want to add the row and put each insurance with each other?

PostgreSQL

It's nice if you tell us those "details" when you post the question.  And you might want to use Request Attention and ask a moderator to add this to the PostGreSQL Zone.  It's also nice to post your test data, or your code set, if you have some code already.

Short answer - mostly this is the same as MySQL.  Longer answer - Why in the world would you choose PostGreSQL instead of the vastly more popular and mature MySQL database?

My database is on PostgrelSQL thats why

Here are links to the PostGreSQL man pages.
http://php.net/manual/en/ref.pgsql.php
https://www.postgresql.org/docs/current/static/index.html

I know how to return number of rows but I dont know how to put each in a column and add the other variables to it.

The code I posted will work with a minor change to post_gres.

require "connection.php";
// Create our result array
$rollup = array();
// Get the rows from the db
$query= "SELECT * from vouchers WHERE parsing_date=CURRENT_DATE ";
$result = pg_query($conn,$query);

// We got rows ...
if ($result) {
  // Loop through results
  while($row = pg_fetch_object($result)) { 
    // Is this the first time we have seen this ID - if so make an entry for it
    if (empty($rollup[$row->id])) {
      $rollup[$row->id] = array('insurance' => $row->insurance, 'rows' => 1);
    }
    // Otherwise add to existing and bump row count
    else {
      $rollup[$row->id]['insurance'] .= ",{$row->insurance}";
      $rollup[$row->id]['rows']++;
    }
  }
}
// Dump the results
echo "<pre>" . print_r($rollup,true) . "</pre>";
echo "<pre>";
foreach($rollup as $k => $v) {
   $rows = $v['rows'] > 1 ? 'rows' : 'row';
    echo "{$k}  {$v['rows']} {$rows} {$v['insurance']}\n";
}
echo "</pre>";

Select allOpen in new window

If you want to output as a table then you can replace lines 25 to 30 with this

echo "<table>";
foreach($rollup as $k => $v) {
   $rows = $v['rows'] > 1 ? 'rows' : 'row';
    echo "<tr><td>{$k}</td><td>{$v['rows']} {$rows}</td><td>{$v['insurance']}</td></tr>";
}
echo "</table>";

Another suggestion is to use PostgreSQL built-in ARRAY_AGG() function.  It's very similar to GROUP_CONCAT() in MySQL.

@Julian Hansen I copied your exact code here:

<?php 
error_reporting(E_ALL);
ini_set('display_errors' ,1);
require "connection.php";
// Create our result array
$rollup = array();
$query= "SELECT * from vouchers WHERE parsing_date=CURRENT_DATE ";
$result = pg_query($conn,$query);

I just got error 500 on the display page

You need to work the sample code into your own code - if you cut and paste without adapting you will have problems

For instance - you have your own <table> echoed from the script - when you pasted my code in you included the <table> I had in my sample.
You can see your sample working against a MySQL database here
However, I would prefer to use the code in my previous post based on Brian's earlier suggestion

<?php 
error_reporting(E_ALL);
ini_set('display_errors' ,1);
require "connection.php";
// Create our result array
$rollup = array();
$query= <<< QUERY
SELECT 
  client_id, 
  count(*) AS rows, 
  array_agg(insurance) AS insurance,
  parsing_date
FROM vouchers 
where parsing_date = CURRENT_DATE
GROUP BY client_id, parsing_date 
QUERY;
$result = pg_query($conn,$query);
echo $conn->error;
?>
