linux php phpexcel

Recently, a tp3.2 project was migrated to the Linux system. Suddenly one day I found that the excel export function that originally ran fine on win server 2008 could not be used on the new system. The error is as follows:

How to solve phpexcel error in Linux system It is said that there is a problem with line 1762. Find the code of this file and take a look:

/**
     * Get an instance of this class
     *
     * @access  public
     * @param   PHPExcel $workbook  Injected workbook for working with a PHPExcel object,
     *                                  or NULL to create a standalone claculation engine
     * @return PHPExcel_Calculation
     */
    public static function getInstance(PHPExcel $workbook = NULL) {
        if ($workbook !== NULL) {            if (isset(self::$_workbookSets[$workbook->getID()])) {                return self::$_workbookSets[$workbook->getID()];
            }            return new PHPExcel_Calculation($workbook);
        }        if (!isset(self::$_instance) || (self::$_instance === NULL)) {            self::$_instance = new PHPExcel_Calculation();
        }        return self::$_instance;
    }   //  function getInstance()

This function getInstance(PHPExcel $workbook = NULL)
I found that there was an extra PHPExcel when this function was defined. I tried to delete it, upload it, and test it, but the error was reported again:

This time it was line 1721, and then I found the file at this location again and deleted PHPExcel. This stuff, then continue to upload and test, most of the errors later are like this, just delete the PHPExcel when the function is defined, but the errors come one after another, this is the file that needs to be replaced:

You need to add a space in this place so that there will be no replacement errors. Okay, continue to upload and test.

Then this happened... I was heartbroken at the time...
Continue to look for problems Well, output the variables in the test php file for testing.

PHPExcel\PHPExcel\Calculation\Functions.php  下面这个文件，中有个 **TYPE**函数，将其中的break去掉，上传，ok了/**
     * TYPE

    public static function TYPE($value = NULL) {
        $value  = self::flattenArrayIndexed($value);        if (is_array($value) && (count($value) > 1)) {            $a = array_keys($value);            $a = array_pop($a);            //  Range of cells is an error
            if (self::isCellValue($a)) {                return 16;            //  Test for Matrix
            } elseif (self::isMatrixValue($a)) {                return 64;
            }
        } elseif(empty($value)) {            //  Empty Cell
            return 1;
        }        $value = self::flattenSingleValue($value);        if (($value === NULL) || (is_float($value)) || (is_int($value))) {                return 1;

            }            return 2;
        }        return 0;
    }   //  function TYPE()

This is the complete process. The online system uses centos7, and PHP is also 7. This is probably caused by incompatibility, and I didn't study it further. After all, there is actually a new excel plug-in. If not, there are too many codes that need to be modified, I guess I will just change the plug-in.
