What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



eregi_replace — Performs a non-case-sensitive POSIX regular expression match and replaces the matches in the subject with the specified replacement.


string eregi_replace(pattern, replace, subject);
string pattern: Regex pattern to match
string replace: Replacement string
string subject: String to search using the pattern


Modified string if the pattern matched; unmodified string if not


This function works like ereg_replace() except for ignoring the case when matching alphabetic characters.
