How to compare two time in PHP

Hi I am new in time functions in php, i have,

@$download_time = date('d-m-Y H:i:s', $dec_time);
$current_time = date('d-m-Y H:i:s');    
$diff = abs(strtotime($current_time) - strtotime($download_time));    
$time=65 // $time is in seconds

Now I want to compare if ($diff < $time) how can I compare with this two values.

Answer 1

If $dec_time is a unix timestamp, then simply:

if (time() - $dec_time < $time) {/* ... */}

Else if it is a textual representation:

if (time() - strtotime($dec_time) < $time) {/* ... */}

Be aware of using needless variables if it’s doesn’t needed later, because you can save a lot of memory if keep an eye of this. If the server’s PHP version is above 5.2, then you can use the DateTime class wich gives you a lot of extended functionality.

I didn’t understood why is the abs() because the download time should be at the past.

Notice:
Keep the @‘s away from your code, because it costs a lot of additional calculations for the PHP interpreter, maybe it is longer to type, but test if the variable exists before, like:

if (!empty($dec_time) && time() - strtotime($dec_time) < $time) {/* ... */}
