How can I check if a xls file is editable file or not, using phpexcel?

Question

I have this input file bootstrap:

This input file only accept xls file, when I send the xls file, first I need check in php if the file is only read or not and return a specific number, because I need accept only editable files.

Example what I need:

I send a xls file, in php I check if is a editable file , if is editable file , continue with the next step, and if is not a editable file, return 3.

This is a only read file:

I work with phpexcel and when I send a only read file , I have the next error:

This is my code in php:

<?php

require "dao/daoExcel.php";
require "vendor/autoload.php";

class ControllerExcel {

    private $aDatosExcel;

    public function setDataExcel($dataexcel) {

        $estado = true;

        if($this->moverArchivo($dataexcel)==false){
            $estado = false;
        }

        if($estado == true && $this->validaHeaders($dataexcel)==false){
            $estado = false;
            return 2;
        }

        if($estado == true){
            return $this->setInsertExcel($dataexcel);
        }

    }

    public function moverArchivo($dataexcel) {


        $fileName = $_FILES["archivo"]["name"]; 
        $fileTmpLoc = $_FILES["archivo"]["tmp_name"];
        $aHeader = new DaoExcel();
        $excelUrl = $aHeader->getHeaderExel($dataexcel);

        $pathAndName = $excelUrl[17]['par_valor'].$fileName;

        $moveResult = move_uploaded_file($fileTmpLoc, $pathAndName);
        if ($moveResult == true) {
           return true;
        }else{
           return false;
        }

    }

    public function validaHeaders($dataexcel){

        $inputFileType = 'Excel5';
        $aHeader = new DaoExcel();
        $excelHead = $aHeader->getHeaderExel($dataexcel);
        $inputFileName = $excelHead[17]['par_valor'].$_FILES["archivo"]["name"];
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcel = $objReader->load($inputFileName);

        $h1 = $objPHPExcel->getActiveSheet()->getCell('A1')->getValue();
        $h2 = $objPHPExcel->getActiveSheet()->getCell('B1')->getValue();
        $h3 = $objPHPExcel->getActiveSheet()->getCell('C1')->getValue();
        $h4 = $objPHPExcel->getActiveSheet()->getCell('D1')->getValue();
        $h5 = $objPHPExcel->getActiveSheet()->getCell('E1')->getValue();

        $header = $h1."###".$h2."###".$h3."###".$h4."###".$h5;

        if($excelHead[16]['par_valor'] == $header){
            return true;
        }else{
            return false;
        }

    }

    public function setInsertExcel($dataexcel){

        $inputFileType = 'Excel5';
        $aHeader = new DaoExcel();
        $excelHead = $aHeader->getHeaderExel($dataexcel);
        $inputFileName = $excelHead[17]['par_valor'].$_FILES["archivo"]["name"];
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcel = $objReader->load($inputFileName);
        $contRows = $objPHPExcel->setActiveSheetIndex(0)->getHighestRow();

        for($i=2;$i<=$contRows;$i++){
            $h1 = $objPHPExcel->getActiveSheet()->getCell('A'.$i)->getValue();
            $h2 = $objPHPExcel->getActiveSheet()->getCell('B'.$i)->getValue();
            $h3 = $objPHPExcel->getActiveSheet()->getCell('C'.$i)->getValue();
            $h4 = $objPHPExcel->getActiveSheet()->getCell('D'.$i)->getValue();
            $h5 = $objPHPExcel->getActiveSheet()->getCell('E'.$i)->getValue();
            $aDatos['ac_no']=$h1;
            $aDatos['custom_no']=$h2;
            $aDatos['nombre']=$h3;
            $aDatos['marc']=$h4;
            $aDatos['estado']=$h5;
            $aDatos['fecha_registro']=$this->setFecha();
            $aDatos['rco_oculto']=0;
            $this->aDatosExcel[]=$aDatos;
        }
        return $aHeader->insertDatosExcel($this->aDatosExcel);
    }

    private function setFecha(){

        date_default_timezone_set("America/Santiago");
        $now = time();
        putenv("TZ=America/Santiago");
        $fecha=date("Y-m-d H:i:s",$now);
        $date=date("Y/m/d H:i:s", strtotime($fecha));
        return $date;

    }

}

?>

So I see that by default,phpexcel only accept editable files , but how can I check by my self if a xls file is only read or not with phpexcel , and return a message?

Sorry by my english.
