error in validation of php file extension when uploading - php

Question

I am trying to validate the file when it is uploading, I am using the following code to achieve it, but I am not getting the desired output.
Even though I am uploading the allowed extension types, I am still getting the echo message "You cannot upload files of this type!". which means the If conditionif (in_array($fileActualExt, $allowed, true)) is not getting true,
thanks in Advance for helping me,
<?php
if(isset($_POST['submit'])) {
if (!empty ($_FILES['file'])){
$fileName = $_FILES['file']['name'];
$fileTempName = $_FILES['file']['tmp_name'];
$fileSize = $_FILES['file']['size'];
$fileError = $_FILES['file']['error'];
$fileType = $_FILES['file']['type'];
$fileExt = explode('.', $fileName);
$fileActualExt = strtolower(end($fileExt));
$allowed = array('jpg', 'jpeg', 'png');
if (in_array($fileActualExt, $allowed, true)) {
if ($fileError === 0) {
if ($fileSize <8000) {
$fileNameNew = uniqid('', true).".".$fileActualExt;
$fileDestination = 'uploads/'.$fileNameNew;
move_uploaded_file($fileTempName, $fileDestination);
header("location: player_home.php?uploadSucess");
echo "success";
}else{
echo "your file is too big";
}
}else{
echo "There was an Error uploading your file!";
}
}else{
echo "You cannot upload files of this type!";
}
}
}
?>
HTML CODE
<form method="post">
<div class="form-group">
<input type="file" name="file">
</div>
<span class="sml">Maximum size of <span>8.0MB</span> for a file.‏
<br>
Allowed Types : jpg, jpeg, png
</span>
<br>
<button class="btn btn-primary" type="submit" name="submit" style="margin-top:15px;">Save</button>
</form>

You may be tripping with the true option in the in_array() method. Remove that and the condition should work.
