已棄用：從 float xx.xxxx 到 int 的隱式轉換在第 922 行的 excel_reader2.php 中丟失了精度

Question

操作系統：Windows 11 PHP 版本 8.1.6

錯誤消息：已棄用：從 float 65.03846153846153 到 int 的隱式轉換在第 922 行的 C:\xampp\htdocs\sati\import\excel_reader2.php 中失去精度

public function __construct($file='',$store_extended_info=true,$outputEncoding='') {

  $this->_ole = new OLERead();
  $this->setUTFEncoder('iconv');
  if ($outputEncoding != '') { 
    $this->setOutputEncoding($outputEncoding);
  }
  for ($i=1; $i<245; $i++) {
    $name = strtolower(( (($i-1)/26>=1)?chr(($i-1)/26+64):'') . chr(($i-1)%26+65));  //line 922
    $this->colnames[$name] = $i;
    $this->colindexes[$i] = $name;
  }
  $this->store_extended_info = $store_extended_info;
  if ($file!="") {
    $this->read($file);
  }
}

任何人都有解決問題的想法？

Answer 1

是的，已棄用

傳遞給chr()時，您應該將計算轉換為整數：

strtolower(
    (
        ($i-1)/26>=1
            ? chr((int) ($i-1)/26+64)
            : ''
    )
    . chr((int) ($i-1)%26+65)
)

固定功能

//function Spreadsheet_Excel_Reader($file='',$store_extended_info=true,$outputEncoding='') { // DEPRECATED EDITED IN 06-2020
    public function __construct($file='',$store_extended_info=true,$outputEncoding='') {    
        $this->_ole = new OLERead();
        $this->setUTFEncoder('iconv');
        if ($outputEncoding != '') { 
            $this->setOutputEncoding($outputEncoding);
        }
        for ($i=1; $i<245; $i++) {

            $name = strtolower(( (($i-1)/26>=1)? chr((int) (($i-1)/26+64)) :'') . chr((int) (($i-1)%26+65)) );
            $this->colnames[$name] = $i;
