<?php
// Sample integers
$num1 = 123456789;
$num2 = -123456789;
$num3 = 65; // ASCII 65 is 'A'

// Notice the double %%, this simply prints a '%' character
printf("%%b = %b ", $num1); // Binary representation
printf("%%c = %c ", $num3); // The ASCII Character
printf("%%d = %d ", $num1); // Standard integer representation
printf("%%d = %d ", $num2); // Standard integer representation
printf("%%e = %e ", $num1); // Scientific notation (lowercase)
printf("%%E = %E ", $num1); // Scientific notation (uppercase)
printf("%%u = %u ", $num1); // Unsigned integer representation (positive)
printf("%%u = %u ", $num2); // Unsigned integer representation (negative)
printf("%%f = %f ", $num1); // Floating-point representation (locale aware)
printf("%%F = %F ", $num1); // Floating-point representation (non-locale aware)
printf("%%g = %g ", $num1); // Shorter of %e and %f
printf("%%G = %G ", $num1); // Shorter of %E and %f
printf("%%o = %o ", $num1); // Octal representation
printf("%%s = %s ", $num1); // String representation
printf("%%x = %x ", $num1); // Hexadecimal representation (lowercase)
printf("%%X = %X ", $num1); // Hexadecimal representation (uppercase)
printf("%%+d = %+d ", $num1); // Sign specifier (positive)
printf("%%+d = %+d ", $num2); // Sign specifier (negative)
