Php: reading, writing, and downloading csv files _ PHP Tutorial-php Tutorial

Php provides a detailed description of csv file reading, writing, and output download operations. Copy the code as follows :? Php?filefopen(text.csv, r); while ($ datafgetcsv ($ file) {print_r ($ data) is used to read a line of content in the CSV each time. The code is as follows:

$ File = fopen('text.csv ', 'r ');

While ($ data = fgetcsv ($ file) {// read the contents of a row in the CSV each time.
// Print_r ($ data); // This is an array. to obtain each data, access the array subscript.
$ Goods_list [] = $ data;
}
// Print_r ($ goods_list );
Echo $ goods_list [0] [1];
Fclose ($ file );
?>

In practice, you often need to download some data from the website to a CSV file for later viewing.
Or use CSV to upload data in batches.
In this case, we need to read and write CSV files.

CSV read operations

The code is as follows:

$ File = fopen ('d:/file/file.csv ', 'r ');
While ($ data = fgetcsv ($ file) {// read the contents of a row in the CSV each time.
Print_r ($ data); // This is an array. to obtain each data, access the array subscript.
}
Fclose ($ file );
?>

CSV write operation

The code is as follows:

$ Fp = fopen ('d:/file/file.csv ', 'w ');
Fputcsv ($ fp, array ('AAA', 'BBB ', 'cccccc '));
Fputcsv ($ fp, array ('mmm', 'yyy', 'hahaha'); // fputcsv can be implemented through array loops.
Fclose ($ fp );
?>

Output CSV (download function)

The code is as follows:

Header ("Content-Type: text/csv ");
Header ("Content-Disposition: attachment; filename=test.csv ");
Header ('cache-Control: must-revalidate, post-check = 0, pre-check = 0 ');
Header ('expires: 0 ');
Header ('pragma: public ');
Echo "id, areaCode, areaName/n ";
Echo "1, cn, china/n ";
Echo "2, us, America/n ";
?>

Output excel (download function)

Header ("Content-type: application/vnd. ms-excel ");
Header ("Content-Disposition: filename = Php100.xls ");
Echo"Id, areaCode, areaName/n";
Echo"1, cn, china/n";
Echo"2, us, America/n";
