regular expression for phone number in php

Question

I am using zend form validation for a phone number. and I want, user should enter phone number in these formats:

"[phone]", "01234567891", "[phone]"

so i am using this regular expression:

"^(?:\+?([0-9]{3})\)?[-. ]?\(?([0-9]{3})\)?[-. ]?([0-9]{10})[-. ]$"

but it is not working. it is generating error :

Fatal error: Uncaught exception 'Zend_Validate_Exception' with message 'Internal error matching pattern '^(?:+?([0-9]{3}))?[-. ]?(?([0-9]{3}))?[-. ]?([0-9]{10})[-. ]$' against value '[phone]'' in /var/www/html/allindiazend/library/Zend/Validate/Regex.php:117 Stack trace: #0 /var/www/html/allindiazend/library/Zend/Validate.php(98): Zend_Validate_Regex->isValid('[phone]')

Zend_Validate->isValid('[phone]')

2 /var/www/html/allindiazend/library/Zend/Filter/Input.php(932):

Zend_Validate->isValid('[phone]')

3 /var/www/html/allindiazend/library/Zend/Filter/Input.php(800):

This expression will match all your 3 examples:

\+?([0-9]{2})-?([0-9]{3})-?([0-9]{6,7})
