Why is this microtime showing up weird in PHP

$start4 = microtime(true);
    // run some php code
$end4 = microtime(true);
print \"Time4: \". ($end4 - $start

E-5 is scientific notation. Seems to happen when you concatenate it with the string value. Try using number_format... ?

print "Time4: ". number_format($end4 - $start4, 10)."
";

//or use:               printf(".10f", $end - $start)
