mb_strpos — Find position of first occurrence of string in a string
$haystack,$needle,$offset = 0,$encoding = nullFinds position of the first occurrence of a string in a string.
Performs a multi-byte safe strpos() operation based on number of characters. The first character's position is 0, the second character position is 1, and so on.
haystackThe string being checked.
needle
The string to find in haystack. In contrast
with strpos(), numeric values are not applied
as the ordinal value of a character.
offsetThe search offset. If it is not specified, 0 is used. A negative offset counts from the end of the string.
encodingO parâmetro encoding
é a codificação de caracteres. Se for omitido ou null, o valor da codificação
de caracteres interna será usado.
Returns the numeric position of
the first occurrence of needle in the
haystack string. If
needle is not found, it returns false.
