sscanf
(PHP 4 >= 4.0.1, PHP 5)
sscanf — Parses input from a string according to a format
Description
mixed sscanf
(
string $str
,
string $format
[,
mixed &$...
] )
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.
Parameters
-
str
-
The input string being parsed.
-
format
-
The interpreted format for str
, which is
described in the documentation for sprintf().
-
...
-
Optionally pass in variables by reference that will contain the parsed values.
Return Values
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.
Examples

list($month, $day, $year) = sscanf($mandate, "%s %d %d");
echo "Item $serial was manufactured on: $year-" . substr($month, 0, 3) . "-$day\n";
?>
If optional parameters are passed, the function will return the
number of assigned values.
