循環瀏覽工作表並清理phpexcel中每個工作表中的列

Question

嘗試循環到每個工作表並清理C列中的任何工作表。我收到消息的安全性索引超出範圍，請幫助。我已添加我的代碼是否有一個步驟缺少。

<?php 
include'../Classes/PHPExcel.php'; 
include'../Classes/PHPExcel/IOFactory.php'; 

$objReader = PHPExcel_IOFactory::createReader('Excel2007'); 
$objPHPExcel = $objReader->load("../upload/combined.xlsx"); 
ini_set('max_execution_time', 2000); 
$i = 0; 
while ($objPHPExcel->setActiveSheetIndex($i)){ 

    $objWorksheet = $objPHPExcel->getActiveSheet(); 
    $highestRow = $objWorksheet->getHighestRow(); 

    for($cl=0;$cl<$highestRow+1;$cl++){ 
     $clean=$objPHPExcel->getActiveSheet()->getCell('C'.$cl)->getValue(); 
     $cleandone=str_replace(',',"",$clean); 
     $objWorksheet->setCellValue('C'.$cl,$cleandone); 
     $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); 
     $objWriter->save('../upload/combined.xlsx'); 
     $i++; 
    } 
} 
echo "Done"; 
?>

請勿保存工作簿每一個細胞變化後

不要試圖訪問的行0，它不存在......行1

不啓動在每個單元格之後增加工作表計數器，但僅在每個工作表之後...實際上，爲什麼不簡單地檢索工作表計數並在foreach中循環，而不是等待您的while嘗試訪問不存在的工作表的錯誤停止前：

<?php 
include'../Classes/PHPExcel.php'; 
include'../Classes/PHPExcel/IOFactory.php'; 

$objReader = PHPExcel_IOFactory::createReader('Excel2007'); 
$objPHPExcel = $objReader->load("../upload/combined.xlsx"); 
ini_set('max_execution_time', 2000); 

$worksheetCount = $objPHPExcel->getSheetCount(); 
for($i=0; $i < $worksheetCount; $i++) { 
    $objPHPExcel->setActiveSheetIndex($i); 
    $objWorksheet = $objPHPExcel->getActiveSheet(); 
    $highestRow = $objWorksheet->getHighestRow(); 

    for($cl=1; $cl<=$highestRow; $cl++) { 
     $clean=$objWorksheet->getCell('C'.$cl)->getValue(); 
     $cleandone=str_replace(',',"",$clean); 
     $objWorksheet->setCellValue('C'.$cl,$cleandone); 
    } 
} 

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); 
$objWriter->save('../upload/combined.xlsx'); 

echo "Done"; 
?>
