PHPEXCEL use notes

The first is to use PHP Reader to read Excle content:

 
require("https://www.ofstack.com/PHPExcel/Classes/PHPExcel.php"); 
$file = "D:\\datas.xlsx"; 
if(!file_exists($file)){ 
die("no file found in {$file}"); 
} 
$datasReader = PHPExcel_IOFactory::load($file); 
$sheets = $datasReader->getAllSheets(); 
// If you have multiple workbooks  
$countSheets = count($sheets); 
$sheetsinfo = array(); 
$sheetData = array(); 
if($countSheets==1){ 
$sheet = $sheets[0]; 
$sheetsinfo["rows"] = $sheet->getHighestRow(); 
$sheetsinfo["column"] = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn()); 
for($row=1;$row<=$sheetsinfo["rows"];$row++){ 
for($column=0;$column<$sheetsinfo["column"];$column++){ 
$sheetData[$column][$row] = $sheet->getCellByColumnAndRow($column, $row)->getValue(); 
} 
} 
}else{ 
foreach ($sheets as $key => $sheet) 
{ 
$sheetsinfo[$key]["rows"] = $sheet->getHighestRow(); 
$sheetsinfo[$key]["column"] = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn()); 
for($row=1;$row<=$sheetsinfo[$key]["rows"];$row++){ 
for($column=0;$column<$sheetsinfo[$key]["column"];$column++){ 
$sheetData[$key][$column][$row] = $sheet->getCellByColumnAndRow($column, $row)->getValue(); 
} 
} 
} 
} 
echo "<pre>"; 
print_r($sheetData); 
echo "</pre>"; 

Note: PHP is used to read excel files. Generally, csv or excel are processed in a well-organized format. xml files can also be read

Note: php above generates excel directly in the form of A tags. If ajax is used, echo $path, window.location.href = returned path will do.
