Infinite loop in foreach on simplex

Question

I am facing a specific problem as I did not find many links. I found the simpleXMLElement and foreach attributes that describe the same problem, but it has not responded for a year and has no answer.

For a little context, I'm trying to use PHPOffice/PHPExcel, and when downloading a file, xlsxthis frame cycle on simplexmlelementin lines 364 to 376 of Excel2007.php, available at https://github.com/PHPOffice/PHPExcel/blob/1.8/Classes/PHPExcel/Reader/Excel2007.php from which several lines are extracted here (I added var_dump and echo):

foreach ( $colourScheme as $k => $xmlColour ) {
    var_dump ( $xmlColour ); echo 'NEWVAR';
    $themePos = array_search ( $k, $themeOrderArray );
    if (! $themePos) {
        $themePos = $themeOrderAdditional ++;
    }
    if (isset ( $xmlColour->sysClr )) {
        $xmlColourData = $xmlColour->sysClr->attributes ();
        $themeColours [$themePos] = $xmlColourData ['lastClr'];
    } elseif (isset ( $xmlColour->srgbClr )) {
        $xmlColourData = $xmlColour->srgbClr->attributes ();
        $themeColours [$themePos] = $xmlColourData ['val'];
    }
}

$colourScheme var simplexmlelement, 12 SimpleXMLElements, thoses 12 simplexmlelement 0 , , "srgbClr".

, $k var 2 , ( 12 $colorScheme), , (, , , ).
