I am getting wrong output i.e. 1194908400
None of this is working i.e. I tried to put double quotes around variable, tried without quotation marks. result is same and wrong.
$d='07-11-13';
echo $d;
echo strtotime($d);
echo "<br>";
echo strtotime("$d");
strtotimecan accept many different formats: php.net/manual/en/function.strtotime.php I believe you're on to the issue though, the function is confusing the month and day
