A small PHP library to handle byte order marks (BOM)

Installation

The recommended method of installing this library is via Composer.

Run the following command from your project root:

$ composer require duncan3dc/bom-string

Usage

Remove the BOM from a string and get back a clean UTF-8 string

use duncan3dc\Bom\Util;

$string = Util::removeBom($bomString);

There's also a stream filter available:

use duncan3dc\Bom\StreamFilter;

stream_filter_register("bom-filter", StreamFilter::class);

$file = fopen($filename, "r");

stream_filter_append($file, "bom-filter");

while ($row = fgetcsv($file)) {
    print_r($row);
}

fclose($file);
