In the following code:
$t = microtime(true);
$now = DateTime::createFromFormat('U.u', $t);
$now = $now->format("H:i:s.v");
Trying to format() will return a fatal error if microtime(true) just so happened to return a float with all zeros as decimals. This is because DateTime::createFromFormat('U.u', $aFloatWithAllZeros) returns false.
Workaround (the while loop is for testing if the solution works):
$t = microtime(true);
$now = DateTime::createFromFormat('U.u', $t);
while (!is_bool($now)) {//for testing solution
$t = microtime(true);
$now = DateTime::createFromFormat('U.u', $t);
}
if (is_bool($now)) {//the problem
$now = DateTime::createFromFormat('U', $t);//the solution
}
$now = $now->format("H:i:s.v");
