The two encoding formats are inconsistent.

// CSV Excel supports GBK encoding and must be converted; otherwise, garbled code $ content = iconv ('utf-8', 'gbk // ignore ', $ content );

Two-dimensional array:

Foreach ($ dataArr as $ key => $ value) {foreach ($ value as $ k1 => $ v1) {$ value [$ k1] = iconv ('utf-8', 'gbk // ignore ', $ v1);} fputcsv ($ fh, $ value );} fclose ($ fh );

It should be about encoding.

// Transcode the header: $ header_data = ['first Column', 'second column']; echo iconv ('utf-8', 'gbk // transtranstranscoder ', '"'. implode ('","', $ header_data ). '"'. "\ n ");

Try it ~

For details, refer to: PHP to read/export CSV files.

Check whether the file content encoding is normal for the csv file you generated or the csv file you sent before?

Mail says it's strange to me
