sscanf ( string str, string format [, string var1])
The function sscanf() is the input analog of
printf(). sscanf() reads
from the string str and interprets it
according to the specified format. If only
two parameters were passed to this function, the values parsed
will be returned as an array.
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.
Example 1. sscanf() Example |
<?php
$serial = sscanf("SN/2350001", "SN/%d");
$mandate = "January 01 2000";
list($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.
Example 2. sscanf() - using optional parameters |
<?php
$auth = "24\tLewis Carroll";
$n = sscanf($auth, "%d\t%s %s", $id, $first, $last);
echo "<author id='$id'>
<firstname>$first</firstname>
<surname>$last</surname>
</author>\n";
?>
