MB_EREG_REPLACE(3)							 1							MB_EREG_REPLACE(3)

mb_ereg_replace - Replace regular expression with multibyte support

SYNOPSIS

       string mb_ereg_replace (string  $pattern, string  $replacement, string  $string, [string  $option = "msr"])

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 in $pattern.

	      o $replacement
		- The replacement text.

	      o $string
		- The string being checked.

	      o $option
		-  Matching  condition	can  be  set by $option parameter. If i is specified for this parameter, the case will be ignored. If x is
		specified, white space will be ignored. If m is specified, match will be executed  in  multiline  mode	and  line  break  will	be
		included  in '.'. If p is specified, match will be executed in POSIX mode, line break will be considered as normal character. If e
		is specified, $replacement string will be evaluated as PHP expression.

RETURN VALUES

	The resultant string on success, 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.
