How to use rows of Mysql array in PHP function? - php

Question

I have a function in PHP and I would like to export an array from my MYSQL Database and then use the rows in a loop to do some stuff with them.
$DB_Server = "XXX.XXX.XXX.XXX";
$DB_Username = "XXXX";
$DB_Password = "XXXXX";
$DB_Database = "XXXXX";
$conn = new mysqli($DB_Server, $DB_Username, $DB_Password, $DB_Database);
$query = "Select Name, Wert from test.DBPBX";
function show(array $options) {
global $showresult, $master, $conn, $query;
$result = mysqli_query($conn, $query);
while ($row = mysqli_fetch_assoc($result)) {
$cnlongname = $row["Name"];
$usercontent = $row["Wert"];
$cn = $cnlongname;
$options['config']->value = 1;
$config = $options["config"]->value;
$show = new SimpleXMLElement("<show/>");
$user = $show->addChild("user");
$user->addAttribute("cn", $cn);
if ($config)
$user->addAttribute("config", "true");
print "cmd: " . htmlspecialchars($show->asXML()) . "\n";
$showresult = $master->Admin($show->asXML());
print "result: " . htmlspecialchars($showresult) . "\n";
$mod = "text=".$usercontent;
$modify = new SimpleXMLElement("$showresult");
$user = $modify->user;
$path = explode("/device/hw/", $mod);
$srch = $user;
$nsegments = count($path);
$i = 1;
foreach ($path as $p) {
if ($i == $nsegments) {
// last part, the modification
list($attr, $value) = explode("=", $p);
$srch[$attr] = $value;
} else {
$srch = $srch->$p;
}
$i++;
}
$modify = new SimpleXMLElement("<modify>" . $user->asXML() . "</modify>");
print "cmd: " . htmlspecialchars($cmd = $modify->asXML()) . "\n";
// do it
$result = $master->Admin($cmd);
print "result: " . htmlspecialchars($result);
}
}
For $cn I would like to use $cnlongname (or $row["Name"]). And for $mod I would like to use $usercontent (or $row["Wert"]). However when I would like to use it I get an error after the first loop:
Warning: mysqli_fetch_assoc() expects parameter 1 to be
mysqli_result, string given in /sample.php on
line 175
Line 175 is:
while ($row = mysqli_fetch_assoc($result)) {
Can you please help me?

Inside your while loop you overwrite your result, therefore you lose your mysql result and cannot query it any more.
// do it
$result = $master->Admin($cmd);
Use a different variable there. :)
