how to call a php function when we open the page - php

Question

/*the function which fetches data from database */public function allClients()
{
try
{
$stmt = $this->conn->query("SELECT * FROM client");
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
return $results;
}
}
catch(PDOException $e)
{
echo $e->getMessage();
}
}
This is the next page where the function is called.I have used a fetch button:'btn-signup' but I want to display this data in a table without using any button how do I do that.
$client2 = new client2();
if (isset($_POST['btn-signup']))
{
try
{
$results=$client2->allClients();
foreach(array ($results) as $row)
{
$id = $row['id'];
$name = $row['name'];
$email = $row['email'];
echo $id."\t\t";
echo $name."\t\t";
echo $email;
echo "\n\n";
}
}
catch(PDOException $e)
{
echo $e->getMessage();
}
}

<table id="data-table-command" class="table table-striped table-vmiddle">
<thead>
<tr>
<th data-column-id="id" data-type="numeric">ID</th>
<th data-column-id="sender">Sender</th>
<th data-column-id="received" data-order="desc">Received</th>
<th data-column-id="commands" data-formatter="commands" data-sortable="false">Commands</th>
</tr>
</thead>
<tbody>
<?php
foreach( array($results) as $row )
{
echo '<tr>';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['name'] . '</td>';
echo '<td>' . $row['email'] . '</td>';
echo '</tr>';
}
?>
</tbody>
</table>
You do the foreach inside your table printing the vars with the proper table markup

Answer 2

So why don't you built your table generic with PHP? As much as I can see you are not doing a AJAX-Request or something like that.
something like:
function table()
{
$client2 = new client2();
if (isset($_POST['btn-signup']))
{
try
{
$results=$client2->allClients();
foreach(array ($results) as $row)
{
echo '<tr>';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['name'] . '</td>';
echo '<td>' . $row['email'] . '</td>';
echo '</tr>';
}
}
catch(PDOException $e)
{
echo $e->getMessage();
}
}
}
/* Set this line where your static rows now are */
<table id="data-table-command" class="table table-striped table-vmiddle">
<thead>
<tr>
<th data-column-id="id" data-type="numeric">ID</th>
<th data-column-id="sender">Sender</th>
<th data-column-id="received" data-order="desc">Received</th>
<th data-column-id="commands" data-formatter="commands" data-sortable="false">Commands</th>
</tr>
</thead>
<tbody>
<?php table(); ?>
</tbody>
</table>

Answer 3

change
echo $id."\t\t";
echo $name."\t\t";
echo $email;
echo "\n\n";
to
echo "<tr><td>$id</td><td>$name</td><td>$email</td></tr>;
And call the function before the close of the table.
And also, you have an extra < /tr> before closing the body tag
</tr></tbody>

The problem was with the function,this is the correct code.It's now working perfectly
public function allClients()//function
{
try
{
$stmt = $this->conn->query("SELECT * FROM client");
$stmt->execute();
$results = $stmt->setFetchMode(PDO::FETCH_ASSOC);
return $stmt;
}
catch(PDOException $e)
{
echo $e->getMessage();
}
}
Function call
<table id="data-table-command" class="table table-striped table-vmiddle">
<thead>
<tr>
<th data-column-id="id" data-type="numeric">ID</th>
<th data-column-id="sender">Sender</th>
<th data-column-id="received" data-order="desc">Received</th>
<th data-column-id="commands" data-formatter="commands" data-sortable="false">Commands</th>
</tr>
</thead>
<tbody>
<?php
$results=$client2->allClients();
foreach($results as $row){
echo "<tr><td>".$row['id']."</td>";
echo "<td>".$row['name']."</td>";
echo "<td>".$row['username']."</td>";
echo "<td>".$row['whatphn']."</td>";
// echo "<td>".$row['email']."</td></tr>";
}
?>
</tbody>
