php - 单元格条目 A1 不再存在于缓存中

Question

我将 PhpOffice\PhpSpreadsheet 与 Apcu 缓存一起使用，并且出现此错误
错误：缓存中不再存在单元格条目 A1。这可能意味着缓存已被其他人清除。

$pool = new \Cache\Adapter\Apcu\ApcuCachePool();
$simpleCache = new \Cache\Bridge\SimpleCache\SimpleCacheBridge($pool);

\PhpOffice\PhpSpreadsheet\Settings::setCache($simpleCache);

$objReader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx");
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load(dirname(__FILE__).'/Tmpfile'.$i.'.xlsx');

$objPHPExcel->setActiveSheetIndex(0);

foreach ( $objPHPExcel->getActiveSheet()->getRowIterator() as $row ) {
    if ( $row->getRowIndex() == 1 ){
        $row->getCellIterator();
        $cellIterator = $row->getCellIterator();
        $cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
        $shop_row = array();
        try {
            foreach ($cellIterator as $key => $cell) { // <<<====== WHERE I got the ERROR
                $key = \PhpOffice\PhpSpreadsheet\Cell\Coordinate::columnIndexFromString($key); ....

我没有任何想法来解决这个问题。

问题来自超出 APCu 允许的内存值 php.ini > apcu > 请更改“apc.shm_size”示例的值：

apc.shm_size=1024M
