在strtotime检查多个字符串

Question

I have this code to check if the mysql timestamp is 24 hours old, it works for one string however I need to check two strings but i'm not sure how to add it in

if(strtotime($dateFrom." + 24 hours") <= strtotime("now"))

for example i'd like to add the string in

if(strtotime($dateFrom **&& $dateTo.**" + 24 hours") <= strtotime("now"))

Answer 1

    if(strtotime($dateFrom." + 24 hours") <= strtotime("now") && 
       strtotime($dateTo." + 24 hours") <= strtotime("now"))
