mb_strpos - Find position of first occurrence of string in a string

SYNOPSIS

       int mb_strpos (string  $haystack, string  $needle, [int	$offset], [string  $encoding = mb_internal_encoding()])

DESCRIPTION

	Finds position of the first occurrence of a string in a string.

	Performs  a  multi-byte  safe strpos(3) operation based on number of characters. The first character's position is 0, the second character
       position is 1, and so on.

PARAMETERS

	      o $haystack
		- The string being checked.

	      o $needle
		- The string to find in $haystack. In contrast with strpos(3), numeric values are not applied as the ordinal value of a character.

	      o $offset
		- The search offset. If it is not specified, 0 is used.

	      o $encoding
		-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.

RETURN VALUES

	Returns the numeric position of the first occurrence of $needle in the $haystack string. If $needle is not found, it returns FALSE.

SEE ALSO

       mb_internal_encoding(3), strpos(3).
