MB_EREGI_REPLACE(3) 1 MB_EREGI_REPLACE(3)mb_eregi_replace - Replace regular expression with multibyte support ignoring caseSYNOPSIS
string mb_eregi_replace (string $pattern, string $replace, string $string, [string $option = "msri"])
DESCRIPTION
Scans $string for matches to $pattern, then replaces the matched text with $replacement.
PARAMETERS
o $pattern
- The regular expression pattern. Multibyte characters may be used. The case will be ignored.
o $replace
- The replacement text.
o $string
- The searched string.
o $option
-$option has the same meaning as in mb_ereg_replace(3).
RETURN VALUES
The resultant string or FALSE on error.
NOTES
Note
The internal encoding or the character encoding specified by mb_regex_encoding(3) will be used as the character encoding for this
function.
Warning
Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace(3)). Not
taking care of this will most likely create remote code execution vulnerabilities in your application.
SEE ALSO mb_regex_encoding(3), mb_ereg_replace(3).
