PHP每周三选择一次

Question

I need help Select every other Wednesday starting on 5/2/12. This code below selects every other Wednesday starting on the week it currently is. But i need to set the beginning week. I am familiar with PHP, but not familiar with php dates. So please be as specific as possible. I found this:

$number_of_dates = 10;

for ($i = 0; $i < $number_of_dates; $i++) {
   echo date('m-d-Y', strtotime('Wednesday +' . ($i * 2) . ' weeks')). "<br>".PHP_EOL;
}

Answer 1

Use mktime to create your starting date and pass that as the second argument to strtotime so that counting starts from there:

$startDate = mktime(0, 0, 0, 5, 2, 2012); // May 2, 2012
for ($i = 0; $i < $number_of_dates; $i++) {
   $date = strtotime('Wednesday +' . ($i * 2) . ' weeks', $startDate);
   echo date('m-d-Y', $date). "<br>".PHP_EOL;
}

See it in action.
