substr
(PHP 3, PHP 4 )
substr -- Return part of a string

Description
string substr (string string, int start [, int
length])

Substr returns the portion of string specified by the start and length parameters.

If start is positive, the returned string will start at the start'th position in string, counting from zero. For instance, in the string 'abcdef', the character at position 0 is 'a', the character at position 2 is 'c', and so forth.

look for examples:
