array not displaying the correct value - php

Question

$data['results'] = $this->lawmodel->getuser($lastName);
$xp = array("lvl1" => 0, "lvl2" => 256, "lvl3" => 567);
foreach ($data['results'] as $row) {
$my_xp = $row->points; // the value is 300
}
for ($i = 0; $i < count($xp); $i++) {
if ($my_xp >= $xp[$i]) {
$data['level'] = $i+1;
break;
}
else {
if (isset($xp[$i+1])) {
if ($my_xp > $xp[$i] && $my_xp <= $xp[$i + 1]) {
$data['next'] = $xp[$i+1],;
break;
}
else {
$data['next'] = $xp[$i],
break;
}
}
}
}
I have a problem the output of $data['level'] = $i+1 is always 1.. I want that it will output the key of an array that the value is equal or greater than $my_xp.
Flow:
If the points of the user is 300 it should be at lvl2.
Plss..i need help..im new in php..:(

Your array
$xp = array("lvl1" => 0, "lvl2" => 256, "lvl3" => 567);
has no integer keys
Try this code:
$data['results'] = $this->lawmodel->getuser($lastName);
$xp = array("lvl1" => 0, "lvl2" => 256, "lvl3" => 567);
$key_prefix = 'lvl';
foreach ($data['results'] as $row) {
$my_xp = $row->points; // the value is 300
}
$previous_xp = 0;
foreach ($xp as $lvl => $xp_value) {
if ($my_xp >= $xp_value) {
$data['level'] = $lvl;
} else {
if ($my_xp > $previous_xp && $my_xp <= $xp_value) {
$data['next'] = $xp_value;
} else {
$data['next'] = $previous_xp;
}
}
$previous_xp = $xp_value;
}
