设置PHP 5.4或更高版本的要求

Question

I need to require at least PHP 5.4 in my app.

The current code detects only 5.0 or higher:

$phpv=phpversion();
$t=explode(".", $phpv);
if($t[0]>=5)
    $ok=1;
else
    $ok=0;

Typing 5.4 or 54 instead of 5 does not work properly.

Answer 1

What about using the second part of the explode :

if($t[0]>=5 && $t[1]>=4)
...

Hope this helps.
