(PHP Extension) Write utf-8 CSV Compatible with Excel

See more CSV Examples

A CSV containing non-English characters that is saved using the utf-8 character encoding must include a BOM (also known as a preamble) if it is to be correctly loaded into Excel. See https://en.wikipedia.org/wiki/Byte_order_mark

This example shows how to save the CSV to a file using utf-8 with a BOM.

Note: This example requires Chilkat v9.5.0.93 or later.

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example program loads a file (japanese.csv)
// that contains this content:
// 
// year,color,country,food
// 2001,red,France,cheese
// 2005,blue,"United States",hamburger
// 2008,green,Italy,pasta
// 1998,orange,Japan,sushi

$success = $csv->LoadFile2('qa_data/csv/test.csv','utf-8');
if ($success != true) {
    print $csv->lastErrorText() . "\n";
    exit;
}

// To save the CSV using utf-8 with a BOM/preamble, 
// add "EMIT_BOM" to the UncommonOptions.
// (This feature was added in Chilkat v9.5.0.93)

$csv->put_UncommonOptions('EMIT_BOM');
$success = $csv->SaveFile2('qa_output/test.csv','utf-8');
if ($success != true) {
    print $csv->lastErrorText() . "\n";
    exit;
}

print 'OK, try to load the CSV in Excel to see if the non-English chars are correct.' . "\n";
