Hi,

Many thanks
Helen

MB_STRPOS(3) 1 MB_STRPOS(3)
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).
