How to compare two Carbon Timestamps?
First, Eloquent automatically converts it's timestamps (created_at, updated_at) into carbon objects. You could just use updated_at to get that nice feature, or specify edited_at in your model in the $dates property:
protected $dates = ['edited_at'];
Now back to your actual question. Carbon has a bunch of comparison functions:
-
eq()equals -
ne()not equals -
gt()greater than -
gte()greater than or equals -
lt()less than -
lte()less than or equals
Usage:
if($model->edited_at->gt($model->created_at)){
// edited at is newer than created at
}
Carbon has a bunch of comparison functions with mnemonic names:
- equalTo()
- notEqualTo()
- greaterThan()
- greaterThanOrEqualTo()
- lessThan()
- lessThanOrEqualTo()
Usage:
if($model->edited_at->greaterThan($model->created_at)){
// edited at is newer than created at
}
Valid for nesbot/carbon 1.36.2
if you are not sure what Carbon version you are on, run this
$composer show "nesbot/carbon"

First, convert the timestamp using the built-in eloquent functionality, as described in this answer.
Then you can just use Carbon's min() or max() function for comparison. For example:
$dt1 = Carbon::create(2012, 1, 1, 0, 0, 0);
$dt2 = Carbon::create(2014, 1, 30, 0, 0, 0);
echo $dt1->min($dt2);
This will echo the lesser of the two dates, which in this case is $dt1.
See http://carbon.nesbot.com/docs/
This is how I am comparing 2 dates, now() and a date from the table
@if (\Carbon\Carbon::now()->lte($item->client->event_date_from))
.....
.....
@endif
Should work just right. I have used the comparison functions provided by Carbon.
