정규식에관한질문을올립니다.

예를 들어서 이런 문장이 있습니다.

---------------------------------------------

CodeIgniter 3.1.0 was released today, with some security fixes, bug fixes and enhancements.Most importantly - it fixes a critical SQL injection bug in the ODBC database driver.

The fixes to the ODBC driver mean that you can no longer use the query builder with it, nor the escape() functions. On the plus side, it now has actual query binding, as opposed to emulated.The ODBC fixes are not backwards compatible, hence the bump in version number. We are also bumping the minimum PHP version to 5.3.7. Any previous in-progress changes,

for CI3.1.0, will now be targeted for CI3.2.0.This release includes bug fixes for the Cache, Config, Database, Database Forge, Email, File Uploading, Form Validation, Image Manipulation, Input Library,

Query Builder, Session, and User Agent libraries; as well as the file and path helpers, and some common functions.
