hi,
i'm not a regex guru myself, but the following regex should work - tabke
a look at my regex test setup ...
<?php
$test = array(
"1",
"1.",
"1.2",
"1.23",
"1.234",
"1234",
"1234.",
"1234.5",
"1234.56",
"1234.567"
);
// if there's a dot, we want at least one number after it.
$regex = '/^\d+(.\d{1,2})?$/';
// test all or numbers ...
foreach ($test as $number) {
if (preg_match($regex, $number)) {
echo "ok ";
} else {
echo "no ";
}
echo $number . "<br />\n";
}
?>
i don't think there's a difference between \d and [0-9], but again, i am
no expert ...
regards,
phillip
