Example #1 numfmt_set_pattern() example

echo 
"Pattern: ".numfmt_get_pattern($fmt)."\n";
echo 
numfmt_format($fmt1234567.891234567890000)."\n";
numfmt_set_pattern($fmt"#0.# kg");
echo 
"Pattern: ".numfmt_get_pattern($fmt)."\n";
echo 
numfmt_format($fmt1234567.891234567890000)."\n";
?>

Example #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
