PHP TCPDF heredoc - php

Question

I got this in my heredoc in my TCPDF.
I basically want to create a dynamic pdf with the data of my database.
$html = <<<EOD
<table border="1">
<thead>
<tr>
<th>firstname</th>
<th>lastname<th>
</tr>
</thead>
<tbody>
<tr>
<th></th>
<th></th>
</tr>
</tbody>
</table>
EOD;
I want to make this dynamic like this, to create the data from my database dynamically.
<?php
foreach($result_set as $result) {
?>
<tr>
<td>
<?php echo $result['firstname']; ?>
</td>
<td>
<?php echo $result['lastname']; ?>
</td>
</tr>
<?php
}
?>
I tried this so far but I cannot find a suitable solution:
$html = <<<EOD
<table border="1">
<thead>
<tr>
<th>Vorname</th>
<th>Nachname</th>
<th>Von</th>
<th>Bis</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<?php echo $result['firstname']; ?>
</td>
<td>
<?php echo $result['lastname']; ?>
</td>
</tr>
</tbody>
</table>
EOD;
can anyone help please.

Answer 1

Ok I somehow did it, but still if there is any better solution feel free to post:)
Code:
$loopHereFirstname = '';
$loopHereLastname = '';
foreach($result_set_random_01 as $result_dish_usr_01) {
$tr_start = '<tr>';
$tr_end = '</tr>';
$td_start = '<td>';
$td_end = '</td>';
$loopHereFirstname .= $result_dish_usr_01['firstname']."\n";
$loopHereLastname .= $result_dish_usr_01['lastname']."\n";
}
$html = <<<EOD
<table border="1">
<thead>
<tr>
<th>firstname</th>
<th>lastname</th>
</tr>
</thead>
<tbody>
$tr_start
$td_start
$loopHereFirstname
$td_end
$td_start
$loopHereLastname
$td_end
$tr_end
</tbody>
</table>
EOD;

You've to break your code into two part if you want to use a loop with <<
<?php
$html =<<<EOD
<table border="1">
<thead>
<tr>
<th>Vorname</th>
<th>Nachname</th>
<th>Von</th>
<th>Bis</th>
</tr>
</thead>
<tbody>
EOD;
foreach($result_set as $result) {
$html.=<<<EOD
<tr>
<td>
{$result['firstname']}
</td>
<td>
{$result['lastname']}
</td>
</tr>
EOD;
}
$html .= '</tbody></table>';
