Phpexcel cannot output Chinese

Problem Description: When using Phpexcel, if the Chinese content is filled in the cell, it will cause the output cell to be empty, even Chinese characters (?!). etc.) are not recognized.

Cause: From the Internet to check is the problem of Utf-8

WORKAROUND: You can use the ICONV function to implement the encoding conversion

This can be accomplished using PHP's own encoding conversion function iconv

$objPHPExcel->setactivesheetindex (0)

->setcellvalue (' A1 ', iconv (' GBK ', ' utf-8 ', ' Chinese Hello '))
->setcellvalue (' B2 ', ' world! ')
->setcellvalue (' C1 ', ' Hello ')
->setcellvalue (' D2 ', ' world! ');
