======printf====== WMPRO, WMMINI FW >= 1.0 WMMEGA FW >= 2.0 Print a formatted string to standard output ====Description==== printf ( string $format [, mixed $values ... ] ) This function will print a formatted string to the current output stream such as a web page or terminal. The output is produced according to the format string using the passed values. The format string is composed of literal text and/or [[#conversion_specifiers|conversion specifiers]]. Each [[#conversion_specifiers|conversion specifier]] fetches one parameter from the values. ====Parameters==== $format: A string with literal text and/or [[#conversion_specifiers|Conversion Specifiers]] $values: Integer, float or string values to be used to produce the formatted string ====Return Values==== None ====Conversion Specifiers==== A conversion specification sequence consists of a ''%'' character followed by one or more of these options in order ending with the required Conversion Type Character: - **Sign:** Optional ''+'' (to be used on a number). By default, only the - sign is used on a number if it's negative. This specifier forces positive numbers to have the + sign attached as well. - **Padding:** Optional ''0'' to pad results with zeroes (to be used on a number with a specified Width). The default is to pad with spaces. - **Alignment:** Optional ''-'' for left-justified. The default is right-justified. - **Width:** Optional integer string, which specifies the minimum number of characters for this conversion. - **Precision:** Optional in the form of a period ''.'' followed by an integer string that specifies how many decimal digits should be displayed for floating-point numbers. When using this specifier on a string, it acts as a cutoff point, setting a maximum character limit to the string. - **Conversion Type:** Required case-sensitive character which specifies how to format the passed values: ^Conversion Type Character^Parameter Value Type^Description of Returned Conversion^ |''c''|Int|The character with that ASCII value| |''d''|Int|A (possibly signed) decimal number| |''f''|Float|A floating-point number| |''s''|String|A string| |''X''|Int|A hexadecimal number (with uppercase letters)| |''%''|(none)|A literal percentage character| Any text in the format string which is not part of a conversion specification sequence (starting with ''%'' and ending with a Conversion Type Character) will be placed into the output as literal text, unchanged. ====Notes==== The mainline PHP specification for this function can be found at http://php.net/manual/en/function.printf.php and is useful for further information. However, the uPHP implementation does not currently support all of the options mentioned there and in the associated sprintf() function at http://php.net/manual/en/function.sprintf.php. ====See Also==== [[sprintf()]] - Return a formatted string [[print()]] - Print data to the current output stream such as a web page or terminal
