[object-htmlimageelement] -xxxxxxxxx。[object-htmlimageelement]在Mac上裁剪图像时出现错误，但完美执行了窗口中的类似代码

Question

我正在使用XAMMP localhost进行项目：在Windows代码中可以完美执行，但是在Mac中，当我尝试裁剪图像时，类似的代码无法按预期工作。

PHP：business_logo.php

$output_dir = 'logo/'; 

if(isset($_FILES["my_business_logo"]))
{
    $error =$_FILES["my_business_logo"]["error"];
   {

        if(!is_array($_FILES["my_business_logo"]['name'])) //single file
        {
            $RandomNum   = time();

            $ImageName      = str_replace(' ','-',strtolower($_FILES['my_business_logo']['name']));
            $ImageType      = $_FILES['my_business_logo']['type']; //"image/png", image/jpeg etc.

            $ImageExt = substr($ImageName, strrpos($ImageName, '.'));
            $ImageExt       = str_replace('.','',$ImageExt);
            $ImageName      = preg_replace("/\.[^.\s]{3,4}$/", "", $ImageName);
            $NewImageName = $ImageName.'-'.$RandomNum.'.'.$ImageExt;
            $url = "$output_dir$NewImageName";

            move_uploaded_file($_FILES["my_business_logo"]["tmp_name"],$output_dir.$NewImageName);
                $check_query = "SELECT * FROM tbl_business_logo WHERE user_id='$pic_id'";
                $query_check = mysqli_query($con, $check_query) or die(mysqli_error($con));
                $no = mysqli_num_rows($query_check);
                if($no == 0){
                $query = "INSERT INTO tbl_business_logo(user_id,account_id,picture,url) VALUES('$pic_id','$account_id','$NewImageName','$url')";
                mysqli_query($con, $query) or die(mysqli_error($con));
                }else{
                $query = "UPDATE tbl_business_logo SET picture='$NewImageName' , url='$url' WHERE user_id='$pic_id'";
                mysqli_query($con, $query) or die(mysqli_error($con));
                }
//                $ret= $output_dir.$NewImageName;
                $ret= '<center><img src="pages/settings/'.$output_dir.$NewImageName.'" style="width: 250px; height: 50px;" class="img-responsive"></center>';
        }
    }
    echo $ret;

}

预期输出：logo-1551522036.png，但在Mac上的实际输出为[object-htmlimageelement] -1555747488。[object-htmlimageelement]
