<para>
To validate if a given value contains only digits and no other characters, simply call
the validator like shown in this example:
</para>
<programlisting language="php"><![CDATA[
$validator = new Zend_Validate_Digits();
$validator->isValid("1234567890"); // returns true
$validator->isValid(1234); // returns true
$validator->isValid('1a234'); // returns false
]]></programlisting>
<note>
<title>Validating numbers</title>
<para>
When you want to validate numbers or numeric values, be aware that this validator
only validates digits. This means that any other sign like a thousand separator or
a comma will not pass this validator. In this case you should use
<classname>Zend_Validate_Int</classname> or
<classname>Zend_Validate_Float</classname>.
