sscanf
Description
mixed sscanf ( string str, string format [, mixed &...] )
The function sscanf() is the input analog of
printf(). sscanf() reads
from the string str
and interprets it
according to the specified format
, which is
described in the documentation for sprintf(). If only
two parameters were passed to this function, the values parsed
will be returned as an array. Otherwise, if optional parameters are passed,
the function will return the number of assigned values. The optional
parameters must be passed by reference.
Any whitespace in the format string matches any whitespace in the input string. This means that even a tab \t in the format string can match a single space character in the input string.
