php number_format oder ähnliches

[Regina Schaukrug]

<?php
$a = array(
        '21,20',
        '21,00',
        '21,22'
    );

foreach ($a as $s) echo germanFloatVal($s). "\n";


function germanFloatVal($s) {
    $n = floatval( str_replace(',', '.', $s ) );
    return str_replace('.', ',',  strval( $n ) );
}

Ausführen:

$ php test.php
21,2
21
21,22

Natürlich geht auch:

function germanFloatVal($s) { 
    return str_replace('.', ',',  strval( floatval( str_replace(',', '.', $s ) ) ) );
}

Oder Du nimmst halt die einfachste Lösung:

<?php
$a = array(
        '21,20',
        '21,00',
        '21,22'
    );

foreach ($a as $s) echo rtrim ( $s , '0,') . "\n";
