Example 2

  <?php  $num1 = 123456789;  $num2 = -123456789;  $char = 50; // The ASCII Character 50 is 2    // Note: The format value “%%” returns a percent sign  printf(“%%b = %b <br>”,$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)  ?>  

Output:

%b = 111010110111100110100010101   %c = 2   %d = 123456789   %d = -123456789   %e = 1.234568e+8   %E = 1.234568E+8

Example 3

  <?php  $num1 = 123456789;  $num2 = -123456789;  $char = 50; // The ASCII Character 50 is 2  // Note: The format value “%%” returns a percent sign  printf(“%%u = %u <br>”,$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  ?>  

Output:

%u = 123456789   %u = 4171510507   %f = 123456789.000000   %F = 123456789.000000   %g = 1.23457e+8   %G = 1.23457E+8   %o = 726746425

Example 4

  <?php  $num1 = 123456789;  $num2 = -123456789;  $char = 50; // The ASCII Character 50 is 2  printf(“%%s = %s <br>”,$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)*/  ?>  

Output:

%s = 123456789   %x = 75bcd15   %X = 75BCD15   %+d = +123456789   %+d = -123456789
