After PHP imports Excel into MySQL database, how to make it appear in text form

After PHP imports Excel into MySQL database, how to make it appear in text form
Like in Excel, it's 9787509345030.
After importing the database, it becomes 9.78750934503E+12.
PHP to read the database data, found also 9.78750934503E+12
To be annoyed, to ask for help, the mood is very complicated.
It seems to be a numerical type, I am obviously
$number = Implode ("', Explode ('-'), $data->sheets[0][' cells '] [$i][1]));
$number = Strval ($number);
Make it into a string type, why is the meter or numerical type????

Your 9787509345030 is not stored as a string in Excel (' 9787509345030 '), but rather as a stylesheet-style (otherwise it is scientific notation)
You can try to read by using the GetFormattedValue method instead of the GetValue method

Your $data->sheets[0][' cells ' [$i][1] There's a problem.

I am csdn a person to learn the wording of the
$data = new Spreadsheet_excel_reader ();
$data->setoutputencoding (' utf-8 ');

$data->read ($upload _file_name);

for ($i = 2; $i <= $data->sheets[0][' numrows '); $i + +)
{
$user _name = $_session[' user_name ');
$book _ISBN = $data->sheets[0][' cells '] [$i][1]));
$book _name = $data->sheets[0][' cells ' [$i][2];
$book _press = $data->sheets[0][' cells ' [$i][3];
}
How did you write it, please?
Formatted read how to write, I looked at the official PHP file to me, I did not read.
