You could look to use strspn or strcspn rather than using the more 'powerful' (for want of a better term) regular expression functions.
PHP Code:
$test = '+44-1234-5678';
if (strcspn($test, '1234567890+-'))
{
echo 'Test contains one or more invalid characters';
}
else
{
echo 'Test is nice and only contains digits, plus or dash';
}
