A demonstration of all possible format values:
<?php $a = 83588709; $num2 = -83588709; $ch = 65; echo sprintf("%%b = %b",$a)."<br>"; // Binary echo sprintf("%%c = %c",$ch)."<br>"; // ASCII echo sprintf("%%d = %d",$a)."<br>"; // Signed decimal echo sprintf("%%e = %e",$a)."<br>"; // lowercase echo sprintf("%%E = %E",$a)."<br>"; // uppercase echo sprintf("%%u = %u",$a)."<br>"; // Unsigned decimal (positive) echo sprintf("%%u = %u",$b)."<br>"; // Unsigned decimal (negative) echo sprintf("%%f = %f",$a)."<br>"; // Floating-point (ls aware) echo sprintf("%%F = %F",$a)."<br>"; // Floating-point (not aware) echo sprintf("%%g = %g",$a)."<br>"; // Shorter of %e and %f echo sprintf("%%G = %G",$a)."<br>"; // Shorter of %E and %f echo sprintf("%%o = %o",$a)."<br>"; // Octal number ?>
Output
%b = 100111110110111011001100101 %c = A %d = 83588709 %e = 8.358871e+7 %E = 8.358871E+7 %u = 83588709 %u = 0 %f = 83588709.000000 %F = 83588709.000000 %g = 8.35887e+7 %G = 8.35887E+7 %o = 476673145
