示例 #1 numfmt_set_pattern() example

    <?php
    $fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
    echo "Pattern: ".numfmt_get_pattern($fmt)."\n";
    echo numfmt_format($fmt, 1234567.891234567890000)."\n";
    numfmt_set_pattern($fmt, "#0.# kg");
    echo "Pattern: ".numfmt_get_pattern($fmt)."\n";
    echo numfmt_format($fmt, 1234567.891234567890000)."\n";
    ?>

示例 #2 OO example

    <?php
    $fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
    echo "Pattern: ".$fmt->getPattern()."\n";
    echo $fmt->format(1234567.891234567890000)."\n";
    $fmt->setPattern("#0.# kg");
    echo "Pattern: ".$fmt->getPattern()."\n";
    echo $fmt->format(1234567.891234567890000)."\n";
