将从excel读取的科学数字转换为csv

Question

I am having an issue while reading from the excel sheet. I am getting my barcode values in scientific format in csv.

How do i parse the original value instead of the scientific number ?

Example : 9,96E+12 [In excel]

9960000000000 [I want this in CSV]

I am using fgetcsv function in php to parse the csv file.

while (($row = fgetcsv($handle, 1000, ';')) !== FALSE)
{
    if(!$header)
        $header = $row;
    else
        $data[] = array_combine($header, $row);
}

Output that i am getting :

[0] => Array
    (
        [code] => FJT8-thr-thrtC2-VSXL
        [barcode] => 9960000000000
        [amount] => 70
        [status] => 1
    )

I want the output as

[0] => Array
    (
        [code] => FJT8-thr-thrtC2-VSXL
        [barcode] => 9,96E+12
        [amount] => 70
        [status] => 1
    )

Answer 1

You can use the floatval() and sprintf function to convert it back and forth as long as you convert the "," to "." before you use the number in PHP.

<?php

$start = '9,96E+12';
$str = floatval(str_replace(',','.',$start)); 

// Proof of concept
echo $start."<br />"; // starting off with 9,96E+12
echo $str."<br />"; // Converted number is 9960000000000
echo sprintf('%.2e',$str); // back to scientific number 9.96e+12


?>
