    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";

    setPattern appears to influence only the behavior of the format method, not the parse method of the NumberFormatter object.

    $pattern = '#,##0';
    $frmtr = NumberFormatter::create('en-US', NumberFormatter::DECIMAL);
    $frmtr->setPattern($pattern);
    echo $frmtr->parse('12.345');

    // returns 12
