qui est la meilleure façon d'obtenir l'entier (0 , 1, 2, ...) de la cellule.

Cette fonction n'existe pas.

Alors, quelle est l'alternative withoput convertir chr en ascii?

Answer 1

$colIndex = PHPExcel_Cell::columnIndexFromString($cell->getColumn()); 

Answer 2

Vous pouvez obtenir l'index des colonnes pendant la répétition.

$xls = PHPExcel_IOFactory::load($fn); 
$xls->setActiveSheetIndex(0); 
$sheet = $xls->getActiveSheet(); 

foreach($sheet->getRowIterator() as $row) 
{ 
    foreach($row->getCellIterator() as $key => $cell) 
    { 
     echo $key; // 0, 1, 2... 
     echo $cell->getCalculatedValue(); // Value here 
    } 
} 

Answer 3

If you want to get decrement cell address using this function, you have to use another function with this function as follows. 

<?php 
echo columnLetter("AB"); 

function columnLetter($c){ 


$letter=""; 
    $c = intval(columnNumber($c)); 
    if ($c<=0) return ''; 

    while($c != 0){ 
     $p = ($c - 1) % 26; 
     $c = intval(($c - $p)/26); 
     $letter = chr(65 + $p) . $letter; 
    } 

    return $letter; 

} 

function columnNumber($col){ 

    $col = str_pad($col,2,'0',STR_PAD_LEFT); 
    $i = ($col{0} == '0') ? 0 : (ord($col{0}) - 64) * 26; 
    $i += ord($col{1}) - 64; 

    return $i-1; 

} 
?>
