Check if $date is equal to 0000-00-00 00:00:00
I want a logic if $due is equal to no date then I want data starting with 2000. My code below is not working.
Be aware of timezones, though. That is, strtotime('0000-00-00 00:00:00 UTC') != strtotime('0000-00-00 00:00:00 EST'). This could also break your compare.
You need to ensure that you are comparing the values in the same format. With what you currently have, on of three things will happen:
If $due is an int, the string you are comparing it with 0000-00-00 00:00:00 will be converted to an int, which will result in 0, and $due will be compared with 0. This will only result in a match if $due === 0. If $due is a bool, the string will be converted to a bool, which will result in TRUE, and you will only get a match if $due === TRUE. If $due is any other type, it will be converted to a string and the two will be compared as strings. You will only get a match if $due === '0000-00-00 00:00:00'.
If would say that you probably need to compare the values as integers. This means that you need to pass any strings through strtotime() - including $due, if it is a string. Since you do not show an example value of $due I cannot provide an exact working code.
If you are storing strtotime() in $due, then you need to compare it like that, too
ReplyDeleteif($due == strtotime('0000-00-00 00:00:00')){
$due = strtotime('2000-00-00 00:00:00');
}
or, more simply
if($due == 0){
$due = strtotime('2000-00-00 00:00:00');
}
but if $due is coming from your db as a string, you would want to strtotime() it:
$due = strtotime($due);
if($due == 0){
$due = strtotime('2000-00-00 00:00:00');
}
