stratotime inbetween dates

[hyster]

I'm trying to get an if statement to determine inbetween 2 dates.

I can get it working if its older than -7 days (single argument) but when I try to add the 2nd condition I get syntax error

$timestamp is coming from a json - unix timestamp

$timestamp = $output2['data'][$acc_id]['last_battle_time'];


$my_date = date('Y-m-d',$timestamp);


if( strtotime($my_date) > strtotime('-7 day') && < strtotime('-14 day') ) {
    echo '   7';
}

I made a basic error :$

 

now I'm stuck with the following, noting happens but the code "executes"

I'm trying to get when the person was last online in a weekly group, 7 - 14 - 21 -28 - over days days ago

$timestamp = $output2['data'][$acc_id]['last_battle_time'];


$my_date = date('Y-m-d',$timestamp);


if( strtotime($my_date) >= strtotime('-1 day') && strtotime($my_date) <= strtotime('-7 day') ) {
    echo '   7';
}elseif( strtotime($my_date) >= strtotime('-7 day') && strtotime($my_date) <= strtotime('-14 day') ) {
    echo '   14';
}elseif( strtotime($my_date) >= strtotime('-14 day') && strtotime($my_date) <= strtotime('-21 day') ) {
    echo '   21';
}elseif( strtotime($my_date) >= strtotime('-21 day') && strtotime($my_date) <= strtotime('-28 day') ) {
    echo '   28';
}

try

$timestamp = $output2['data'][$acc_id]['last_battle_time'];

$dt1 = new DateTime();
$dt1->setTimestamp($timestamp);

$dt2 = new DateTime();

echo ceil($dt1->diff($dt2)->days / 7) * 7;

Aside from Barand's response, I would add the following comments on your code.

 

In the first code you posted, the conditions in the if() clause was wrong. Each condition joined with AND/OR clauses must be independent.

 

if( strtotime($my_date) > strtotime('-7 day') && < strtotime('-14 day') ) {

The red condition is incomplete.

 

 

On your second posted code, the conditions are impossible!

 

 

 

if( strtotime($my_date) >= strtotime('-1 day') && strtotime($my_date) <= strtotime('-7 day') ) {

echo ' 7';
}

A date cannot be greater than yesterday (-1) AND also be less than 7 days ago. The operators need to be reversed.
