remove all strings from microtime and add minutes to it

im usng this code to get php microtime

$date = round(microtime(true) * 1000);

on the localhost everything was ok and getting just numbers BUT on the server it's gettings numbers and String and a dot(.)

Question 2

also how do i added more 15 minute to the current microtime

Solution

  • You can use filter_var to sanitize the variable to only hold numerical values, using FILTER_SANITIZE_NUMBER_INT

    For example;

    echo filter_var($date, FILTER_SANITIZE_NUMBER_INT);

    Using Mark Bakers comment, to add 15 minutes, you would just do the following;

    echo filter_var( ($date + 15 * 60 * 1000), FILTER_SANITIZE_NUMBER_INT);

    Edit

    You can use a regular expression to remove any characters that are not numeric. For example

    preg_replace("/[^0-9]/", "", $date);

    Edit 2

    You can capture the last part of the string by using the following regular expression

    $re = "~\s(\d+)~"; 
$str = "12 + 142020602353 "; 
preg_match($re, $str, $m);
echo $m[0];
