function running in foreach loop - php

Question

thank you for taking time to look at this. I have been dealing with this annoying foreach loop. Here is what I am trying to do.
I have the first page "form.php".
On this page I have check boxes. Each check box is generated from a database table. Here is the code:
<?php
include("config.php");
$mysqli = new mysqli($host, $db_uname, $db_pass, $db);
$query = "SELECT * FROM `plugins` WHERE 1";
if ($result = $mysqli->query($query)) {
echo '<form action="test.php" method="post">
<input name="gname" placeholder="Group Name..."/>
<table width="200">
';
while ($row = $result->fetch_assoc()) {
echo '<tr><td>
<label>
<input type="checkbox" value="'.$row["plugin"].'" name="checkbox[]">
'.$row["plugin"].'
</label>
</td></tr>';
}
echo '
</table>
<select name="permplugin">
<option>Select One...</option>';
$query2 = "SELECT * FROM `permission_types` WHERE 1";
if ($result2 = $mysqli->query($query2)) {
echo '<h3>Select Permission format below</h3><hr />';
while ($row2 = $result2->fetch_assoc()) {
echo '
<option value="'.$row2["plugin_name"].'">'.$row2["plugin_name"].'</option>';
}
echo '
</select>
<br />
<input name="" type="reset"><input name="" type="submit">
</form>';
}
}
?>
Now after that it sends the checked boxes to "test.php"
here is the code for that:
<?php
if(!empty($_POST['checkbox']) || !empty($_POST['select']) || !empty($_POST['gname'])) {
echo '<h1>'.$_POST['gname'].'</h1>';
$check1 = $_POST['checkbox'];
foreach($check1 as $check) {
include "functions.php";
checkboxes($check);
}
echo '<h3>Selected Permission format below</h3><hr />';
echo $_POST['permplugin'];
} else {
echo "please select atleast one plugin.";
}
?>
The functions page code looks like this:
<?php
//all functions are here.
function checkboxes($check){
$mysqli_perm = new mysqli("localhost", "uname", "pword", "tcordero_permnodes");
$query_perm = "SELECT * FROM permission_nodes WHERE plugin = `$check`";
if ($result_perm = $mysqli_perm->query($query_perm)) {
echo $check;
/* fetch associative array */
while ($row_perm = $result_perm->fetch_assoc()) {
echo $row_perm['node'].'<br />';
}
unset($check);
}
}
When I run the test.php I get this error:
Fatal error: Cannot redeclare checkboxes() (previously declared in C:\xampp\htdocs\TPYC\functions.php:3) in C:\xampp\htdocs\TPYC\functions.php on line 15
What am I doing wrong?

You need to take the include out of the foreach loop. Try this:
include "functions.php";
foreach($check1 as $check) {
checkboxes($check);
}
