PHP move_uploaded_file not working but no errors either? - php

Question

I'm trying to move my uploaded file to a pictures folder. I dont get any errors when it comes to the script. Im using godaddy as the host. All file permissions are set up correctly. Have really no idea what else to do.
This is the php code:
<?php
public function CheckPicture($picture){
if(empty($_FILES['picture']['name'])){
echo "Must choose a file.";
}else{
$allowed = array('jpg', 'jpeg', 'png');
$file_name = $_FILES['picture']['name'];
//line 157->$file_extn = strtolower(end(explode('.', $file_name)));
$file_temp = $_FILES['picture']['tmp_name'];
if(in_array($file_extn, $allowed)){
$this->UploadPicture($username, $file_name, $file_extn);
}else{
echo $file_extn;
echo "Incorect file type. Types allowed: ";
echo implode(', ' , $allowed);
}
}
}
public function UploadPicture($username, $file_temp, $file_extn){
ini_set('display_errors',1);
error_reporting(E_ALL);
$file_path = '/home/content/49/11554349/html/gb/dev/images/pictures/' . substr(md5(time()), 0 , 9) . '.' . $file_extn;
move_uploaded_file($file_temp, $file_path);
echo $file_path;
print_r("$file_temp");
}
?>
This is how I am calling it in the html:
<?php
session_start();
include_once('post.php');
$username = unserialize($_SESSION["username"]);
$email = $_SESSION["email"];
if(!$_SESSION["username"]){
header("Location: http://www.greenboardapp.com/dev/");
}
if(isset($_FILES['picture'])){
$upload = new Post();
$upload->CheckPicture($picture);
}
?>
This is the form:
<div class="tile">
<img src="images/profileimg.png" alt="Tutors" class="tile-image">
<form action="profile.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="picture"><br>
<h6><input type="submit" value="Change Profile Pic" class="btn btn-hg btn-success"></h6>
</form>
</div>

Answer 1

The problem is, that end requires a reference, because it modifies the internal representation of the array (it makes the current element pointer point to the last element).
The result of explode('.', $file_name) cannot be turned into a reference. This is a restriction in the PHP language, that probably exists for simplicity reasons.
Output for 5.1.0 - 5.5.6
Strict Standards: Only variables should be passed by reference

Success
Solution
Find:
$file_extn = strtolower(end(explode('.', $file_name)));
$file_temp = $picture['tmp_name'];
Change to:
$file_extn_ex = explode('.', $file_name);
$file_extn_end = end($file_extn_ex);
$file_extn = strtolower($file_extn_end);
$file_temp = $picture['tmp_name'];
