php - How to check "March 21, 2015" string is a valid date?

Question

I am having a variable which holds date as string like March 21, 2015,so I need to check whether it is a valid in php.I tries to check using

$date = 'July 20 2018'; echo date('d/m/Y', strtotime($date));

But it showing error and also tried

if (DateTime::createFromFormat('Y-m-d G:i:s', $myString) !== FALSE) { //valid date }

Getting error 2nd parameter must be string. Please anybody can help me !

So, `$myString` is not a string. Find a value which is __string__. — u_mulder, May 05 '18 at 11:52
Also, in your call to `createFromFormat()`, `'Y-m-d G:i:s'` doesn't match to your format. — Syscall, May 05 '18 at 11:56

strtotime will parse the date string to a number: please refer to this.

so the returned value from strtotime cannot be passed to createfromFromat as the second parameter.

You can use the following code to verify the date

$date = DateTime::createFromFormat('July 25 2010', 'F j Y');
return $date && ($date->format('F j Y') === 'July 25 2010');
