Description

Object-oriented style

Procedural style

intfloatfalse numfmt_parse(
    NumberFormatter $formatter,
    string $string,
    int $type = NumberFormatter::TYPE_DOUBLE,
    int &$offset = null
)

Parse a string into a number using the current formatter rules.

Parameters

formatter: NumberFormatter object.
string: The string to parse for the number.
type: The formatting type to use. By default, NumberFormatter::TYPE_DOUBLE is used. Note that NumberFormatter::TYPE_CURRENCY is not supported; use NumberFormatter::parseCurrency instead.

Examples

Example #1 numfmt_parse example

<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
$num = "1.234.567,891";
echo numfmt_parse($fmt, $num)."\n";
echo numfmt_parse($fmt, $num, NumberFormatter::TYPE_INT32)."\n";
?>

Example #2 OO example

<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
$num = "1.234.567,891";
echo $fmt->parse($num)."\n";
echo $fmt->parse($num, NumberFormatter::TYPE_INT32)."\n";
