villain222 Posted September 16, 2010 Share Posted September 16, 2010 I'm trying to make a script to check a files date time and if its under so many seconds long the page will refresh. here is what I've got. I've been testing the output of the date() functions but when i do the math all i get is a 0. where did i go wrong? is it just i can't do math with dates? Thanks in advanced. <html><head> <meta http-Equiv="Cache-Control" Content="no-cache"> <meta http-Equiv="Pragma" Content="no-cache"> <meta http-Equiv="Expires" Content="0"> <? $proFile = "profilePics/profile.jpg"; //if ( date ("m d Y H:i:s.") - date ("m d Y H:i:s.", filemtime($proFile)) <= 00 00 0000 00:00:04 ){ //this is where the magic should happen. //echo "<meta http-equiv="refresh" content='4'>"; } ?> </head> <? echo date ("m d Y H:i:s."); echo "<br>"; echo date ("m d Y H:i:s.", filemtime($proFile)); echo "<br>"; echo date ("m d Y H:i:s.") - date ("m d Y H:i:s.", filemtime($proFile)); //only outputs 0 ?> Link to comment https://forums.phpfreaks.com/topic/213540-dates-and-some-math/ Share on other sites More sharing options...
