Formatting Phone Numbers in PHP
问题 I am working on an SMS app and need to be able to convert the sender's phone number from +11234567890 to 123-456-7890 so it can be compared to records in a MySQL database . The numbers are stored in the latter format for use elsewhere on the site and I would rather not change that format as it would require modifying a lot of code. How would I go about this with PHP? Thanks! 回答1: $data = '+11234567890'; if( preg_match( '/^\+\d(\d{3})(\d{3})(\d{4})$/', $data, $matches ) ) { $result = $matches
