Use printf() to demonstrate all possible format values in PHP

Description

The following code shows how to use printf() to demonstrate all possible format values.

Example


  // w w w.j av  a 2 s. c o  m
<?php
   $num1 = 123456789;
   $num2 = -123456789;
   $char = 50; // The ASCII Character 50 is 2
   
   // The format value "%%" returns a percent sign
   printf("%%b = %b <br>",$num1); // Binary number
   printf("%%c = %c <br>",$char); // The ASCII Character
   printf("%%d = %d <br>",$num1); // Signed decimal number
   printf("%%d = %d <br>",$num2); // Signed decimal number
   printf("%%e = %e <br>",$num1); // Scientific notation (lowercase)
   printf("%%E = %E <br>",$num1); // Scientific notation (uppercase)
   printf("%%u = %u <br>",$num1); // Unsigned decimal number (positive)
   printf("%%u = %u <br>",$num2); // Unsigned decimal number (negative)
   printf("%%f = %f <br>",$num1); // Floating-point number (local settings aware)
   printf("%%F = %F <br>",$num1); // Floating-point number (not local settings aware)
   printf("%%g = %g <br>",$num1); // Shorter of %e and %f
   printf("%%G = %G <br>",$num1); // Shorter of %E and %f
   printf("%%o = %o <br>",$num1); // Octal number
   printf("%%s = %s <br>",$num1); // String
   printf("%%x = %x <br>",$num1); // Hexadecimal number (lowercase)
   printf("%%X = %X <br>",$num1); // Hexadecimal number (uppercase)
   printf("%%+d = %+d <br>",$num1); // Sign specifier (positive)
   printf("%%+d = %+d <br>",$num2); // Sign specifier (negative)
?>

The code above generates the following result.
