sscanf

Name

sscanf — Parses input from a string according to a specified format.

Synopsis

mixed sscanf(string, format[, $variables]); string string: String to parse string format: Format to use mixed $variables (optional): One or more variables to store

Returns

Integer or array; FALSE on error

Description

sscanf() parses string into variables based on the format string. The format string uses the same conversion specifiers as sprintf() ; however, instead of formatting and transforming variables, it provides a template with which to parse a string into variables. See sprintf() for a complete list of conversion specifiers.

This function accepts two or more arguments. If only two arguments are provided, the data parsed from string are returned as a numerically keyed array. If additional arguments are passed to the function, the data parsed out of string are stored in them. If there are more specifiers than variables to contain them, an error is generated. If the opposite is true, the extra variables contain NULL .

Note

sscanf() is best suited to dealing with simple strings that follow consistent fixed formats. For more robust functionality, use the Perl-style regular expression library.

Version

PHP 4.0.1+

Example

Example 1216. Parse data out of a simple formatted string

<?php
$string = 'age:27 height:1.83m weight:90kg';
sscanf($string, 'age:%d height:%fm weight:%dkg', $age, $height, $weight);

// use var_dump to show the types, as well as the values
var_dump($age, $height, $weight);
?>

Output:
int(27)
float(1.83)
int(90)
