Question

我正在使用PHPExcel加载一个大小为10 KB（40行和18列）的非常小的excel文件，但它总是给我内存大小错误。我知道文件大小非常小，因此代码中有问题但无法弄清楚。

ini_set('memory_limit', '-1');
$this->load->library('PHPExcel');
$cacheMethod = PHPExcel_CachedObjectStorageFactory:: cache_to_phpTemp;
$cacheSettings = array( ' memoryCacheSize ' => '8MB');
PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings);

$data = excelToArray($upload_filename);

我使用了一个函数来加载文件内容并将其转换为数组：

function excelToArray($filePath, $header=true){
        //Create excel reader after determining the file type
        $inputFileName = $filePath;
        /**  Identify the type of $inputFileName  **/
        $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
        /**  Create a new Reader of the type that has been identified  **/
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        /** Set read type to read cell data onl **/
        $objReader->setReadDataOnly(true);
        /**  Load $inputFileName to a PHPExcel Object  **/
        $objPHPExcel = $objReader->load($inputFileName);
        //Get worksheet and built array with first row as header
        $objWorksheet = $objPHPExcel->getActiveSheet();
        //excel with first row header, use header as key
        if($header){
            $highestRow = $objWorksheet->getHighestDataRow();
            $highestColumn = $objWorksheet->getHighestDataColumn();
            $headingsArray = $objWorksheet->rangeToArray('A1:'.$highestColumn.'1',null, true, true, true);
            $headingsArray = $headingsArray[1];
            $r = -1;
            $namedDataArray = array();
            for ($row = 3; $row <= $highestRow; ++$row) {
                $dataRow = $objWorksheet->rangeToArray('A'.$row.':'.$highestColumn.$row,null, true, true, true);
                if ((isset($dataRow[$row]['A'])) && ($dataRow[$row]['A'] > '')) {
                    ++$r;
                    foreach($headingsArray as $columnKey => $columnHeading) {
                        $namedDataArray[$r][$columnHeading] = $dataRow[$row][$columnKey];
                    }
                }
            }
        }
        else{
            //excel sheet with no header
            $namedDataArray = $objWorksheet->toArray(null,true,true,true);
        }
        return $namedDataArray;
}

我试图将其缩小到脚本失败的后续行：

$objPHPExcel = $objReader->load($inputFileName);

另一个要点是，此代码在localhost上正常工作，但在godaddy服务器上出错。

Answer 1

1）您可以编辑php.ini中的memory_limit行（如果您有权访问该文件）将内存增加到64M：

memory_limit = 64M;

2）如果您无法访问php.ini文件，请将此行添加到.htaccess文件的顶部：

php_value memory_limit 64M

如果这不起作用或引发＆＃34; 500内部服务器错误＆＃34;，请从.htaccess中删除该行。
