Creating a table with PHP - php

Question

I am trying to create a table using PHP.
For some reason I can't display the key. Any idea why?
Here's the table.
Here's my code that I tried:
<table>
<?php
$users = array(
array('first_name' => 'RS', 'last_name' => 'AD'),
array('first_name' => 'SQ', 'last_name' => 'FS'),
array('first_name' => 'SA', 'last_name' => 'Guillen'),
array('first_name' => 'AS', 'last_name' => 'Gs')
);
$array_number = count($users)-1;
foreach($users as $key => $user) {
for($i=0; $i<=$array_number; $i++){
echo $users[$i]['first_name'].' '. $users[$i]['last_name'].'<br>';
}
}
?>
</table>
Any idea?

Answer 1

Try this
<table>
<tr>
<th>User #</th>
<th>First Name</th>
<th>Last Name</th>
<th>Full Name</th>
<th>Full Name in UpperCase</th>
</tr>
<?php
$users = array(
array('first_name' => 'Michael', 'last_name' => 'Choi'),
array('first_name' => 'John', 'last_name' => 'Supsupin'),
array('first_name' => 'Mark', 'last_name' => 'Guillen'),
array('first_name' => 'KB', 'last_name' => 'Tonel')
);
foreach ($users as $key => $user) {
echo "<tr>";
echo "<td>" , $key + 1 , "</td>";
echo "<td>" . $user['first_name'] . "</td>";
echo "<td>" . $user['last_name'] . "</td>";
echo "<td>" . $user['first_name'] . " " . $user['last_name'] . "</td>";
echo "<td>" . strtoupper($user['first_name']) . " " . strtoupper($user['last_name']) . "</td>";
echo "<td></td>";
echo "</tr>";
}
?>
</table>
Brief Explanation:
As you have shown within your image you need to define predefined headings which can be done using <th></th> and rest of those values you were getting from an $users array which can be placed within loop.
Note: Here you need to use single loop not nested loops as shown in example

Answer 2

The problem is that you loop over the array twice, once with the foreach and inside that with the for. But you need only one loop. Choose one.
Also, make it a habit to always use htmlspecialchars when echoing the contents of a variable. In this case it won't matter, but sometimes, you won't know where the variable has been!
Also, see Amol's answer.

Answer 3

You should use <tr> and <td>.
<table border="1">
<?php
$users = array(
array('first_name' => 'Michael', 'last_name' => 'Choi'),
array('first_name' => 'John', 'last_name' => 'Supsupin'),
array('first_name' => 'Mark', 'last_name' => 'Guillen'),
array('first_name' => 'KB', 'last_name' => 'Tonel')
);
$array_number = count($users)-1;
for($i=0; $i<=$array_number; $i++){
?>
<tr> <td><?php echo $users[$i]['first_name']; ?></td><td><?php echo $users[$i]['last_name']; ?></td> </tr>
<?php }
?>
</table>

Answer 4

<table> <?php
$users = array( array('first_name' => 'Michael', 'last_name' => 'Choi'), array('first_name' => 'John', 'last_name' => 'Supsupin'), array('first_name' => 'Mark', 'last_name' => 'Guillen'), array('first_name' => 'KB', 'last_name' => 'Tonel') );
$i = 1;
foreach($users as $key => $user) {
echo "<tr>";
echo "<td>" . $i . "</td>";
echo "<td>" . $user['first_name'] . "</td>";
echo "<td>" . $user['last_name'] . "</td>";
echo "</tr>"; $i++;
}
?>
</table>
