PHP sscanf() Function

Complete PHP String Reference

Definition and Usage

The sscanf() function parses input from a string according to a specified format. The sscanf() function parses a string into variables based on the format string.

If only two parameters are passed to this function, the data will be returned as an array. Otherwise, if optional parameters are passed, the data parsed are stored in them. If there are more specifiers than variables to contain them, an error occurs. However, if there are less specifiers than variables, the extra variables contain NULL.

Syntax

sscanf(string,format,arg1,arg2,arg++)

Parameter	Description
string	Required. Specifies the string to read
format	Required. Specifies the format to use. Possible format values: %% - Returns a percent sign %b - Binary number %c - The character according to the ASCII value %d - Signed decimal number %e - Scientific notation (e.g. 1.2e+2) %u - Unsigned decimal number %f - Floating-point number (local settings aware) %F - Floating-point number (not local settings aware) %o - Octal number %s - String %x - Hexadecimal number (lowercase letters) %X - Hexadecimal number (uppercase letters) Additional format values. These are placed between the % and the letter (example %.2f): + (Forces both + and - in front of numbers. By default, only negative numbers are marked) ' (Specifies what to use as padding. Default is space. Must be used together with the width specifier. Example: %'x20s (this uses "x" as padding) - (Left-justifies the variable value) [0-9] (Specifies the minimum width held of to the variable value) .[0-9] (Specifies the number of decimal digits or maximum string length) Note: If multiple additional format values are used, they must be in the same order as above.
arg1	Optional. The first variable to store data in
arg2	Optional. The second variable to store data in
arg++	Optional. The third, fourth, and so on, to store data in

Example 1

<?php
$string = "age:30 weight:60kg";
sscanf($string,"age:%d weight:%dkg",$age,$weight);
// show types and values
var_dump($age,$weight);
?>

The output of the code above will be:

int(30)
int(60)
