The MongoRegex class

(PECL mongo >=0.8.1)

Introduction

This class can be used to create regular expressions. Typically, these expressions will be used to query the database and find matching strings. More unusually, they can be saved to the database and retrieved.

Regular expressions consist of four parts. First a / as starting delimiter, then then pattern, another / and finally a string containing flags.

Example #1 Regular expression pattern

/pattern/flags

MongoDB recognizes six regular expression flags:

  • i: Case insensitive

  • m: Multiline

  • x: Can contain comments

  • l: locale

  • s: dotall, "." matches everything, including newlines

  • u: match unicode
