使用echo语句显示上传图像的完整URL

I found a upload script that is perfect for needs as it renames images here.

Works great but need to modify so it displays the full URL to image after uploaded.

Have working to some extent but stuck and need input.

My mod to the above referenced script:

$url  = isset($_SERVER['HTTPS']) ? 'https://' : 'http://';
        $url .= $_SERVER['SERVER_NAME'];
        $url .= $_SERVER['REQUEST_URI'];

        echo dirname(dirname($url)).$uploadResult;
        echo "<br />";
        echo "<br />";
        echo "<a href='$uploadResult' target='_blank'><img src='$uploadResult' alt='picture'></a><br/>";
        echo "<br />";
        echo "<form><input name='imgcode' size='60' type='text' value='$uploadResult' /></form>";
        echo "<br />";

Above outputs like this:

enter image description here

The issue I have is: need to remove the .. from path (../images/01092016211821.gif)

Have explored and attempted the str_replace function but cannot get working.

Would also like to echo the full image URL path inside input area to make copying easy.

Thanks in advance for advice/solution.

Here is full script...

example.php:

<?php   
    if(isset($_POST["Send"])){      // If form is submited
        require_once("uploadClass.php");    
        $file=$_FILES["fileField"];                 // Get file from form

        $destination="../images/";
        if (!file_exists($destination)) {       // If 'destination' folder dosn't exist, create
            mkdir($destination);
        }

        $process=new Upload($destination);      // Set 'destination' as new default destination folder for upload

        $uploadResult=$process->executeUpload($file);   // Attach file to upload process

        $url  = isset($_SERVER['HTTPS']) ? 'https://' : 'http://';
        $url .= $_SERVER['SERVER_NAME'];
        $url .= $_SERVER['REQUEST_URI'];

        echo dirname(dirname($url)).$uploadResult;
        echo "<br />";
        echo "<br />";
        echo "<a href='$uploadResult' target='_blank'><img src='$uploadResult' alt='picture'></a><br/>";
        echo "<br />";
        echo "<form><input name='imgcode' size='60' type='text' value='{dirname(dirname($url).$uploadresult)}' /></form>";
        echo "<br />";
        }
?>

            <td>
                <input type="file" name="fileField" id="fileField" placeholder="">

            $i=0;

                return NULL;
            }
        }
    }
?>

My Solution based on input from @Forbs response:

<?php   
    if(isset($_POST["Send"])){      // If form is submited
        require_once("uploadClass.php");    
        $file=$_FILES["fileField"];                 // Get file from form

        $destination="../images/";
        if (!file_exists($destination)) {       // If 'destination' folder dosn't exist, create
            mkdir($destination);
        }

        $process=new Upload($destination);      // Set 'destination' as new default destination folder for upload

        $uploadResult=$process->executeUpload($file);   // Attach file to upload process

        $url  = isset($_SERVER['HTTPS']) ? 'https://' : 'http://';
        $url .= $_SERVER['SERVER_NAME'];
        $url .= $_SERVER['REQUEST_URI'];

        if (substr($uploadResult,0,2) == "..")
        $uploadResult = substr($uploadResult,2);

        echo dirname(dirname($url)).$uploadResult;
        echo "<br />";
        echo "<br />";

        }
?>

<form action="?" method="POST" enctype="multipart/form-data">
    <table id="dyntable" class="table table-bordered">
        <tr>
            <td>
                File
            </td>
            <td>
                <input type="file" name="fileField" id="fileField" placeholder="">
            </td>
        </tr>
        <tr>
            <td colspan="2">
                <center>
                    <button type="submit" name="Send">Send</button>
                    <button type="reset">Reset</button>
                </center>
            </td>
        </tr>
    </table>
</form>

<textarea id="myText" rows="3" cols="80"><?php echo dirname(dirname($url)).$uploadResult; ?></textarea>

Solves my issue good enough to finish project.

    1) Remove the leading two periods if they appear right?

     if (substr($uploadresult,0,2) == "..")
        $uploadresult = substr($uploadresult,2);
    

    2) why not change the input to

    value ='{dirname(dirname($url).$uploadresult)}' to solve that?
