Check to make sure image is either dimensions?

[cscodismith]

I have a function on my website that is not yet released that admins will use to make posts on the homepage. Part of this function involves uploading an image and there is currently no check for this but would like to make it so that it will check to make sure that they are only uploading images that are either one of the following resolutions:

1920px width;1080px height
1280px width;720px height

I am not to sure how to check this but my current code for uploading images looks like the following:

<?php
function uploadImage() {
    $target_dir = "uploads/";
    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    // Check if image file is a actual image or fake image
    if(isset($_POST["submit"])) {
        $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
        if($check !== false) {
            $uploadOk = 1;
        } else {
            echo "File is not an image.";
            $uploadOk = 0;
        }
    }
    // Check if file already exists
    if (file_exists($target_file)) {
        echo "Sorry, file already exists.";
        $uploadOk = 0;
    }
    // Check file size
    if ($_FILES["fileToUpload"]["size"] > 500000) {
        echo "Sorry, your file is too large.";
        $uploadOk = 0;
    }
    // Allow certain file formats
    if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg") {
        echo "Sorry, only JPG, JPEG, & PNG files are allowed.";
        $uploadOk = 0;
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
            return $target_file;
        } else {
            echo "Sorry, there was an error uploading your file.";
        }
    }

Untested but it might work if you change

if($check !== false) {

to

if ( ($check !== false) && ($check[0] == 1920 && $check[1] == 1080) || ($check[0] == 1280 && $check[1] == 720) ) {

Unfortunately this doesn’t check it the way I would like. It still allows any size image to be uploaded :(
