检查有效日期类型

Question

may be this question had been asked, I've searched but still not confident about my problem..

my problem is checking valid date from string

$a='23-June-11'; //valid
$b='Normal String';//invalid

I want to convert $a and $b using strtotime() before I do that, of course i want to validate whether $a or $b is a valid date format

From $a i can get 23, 11 using explode function, but how about 'June'? using function above, 'June' is not numeric

Answer 1

Why not let strtotime() do the validation?

It will return false if it's an invalid date.

Otherwise, you'd have to rebuild strtotime()'s functionality in order to do the validation - sounds like a futile (and big) exercise to me.
