Convert Datetime to PHP

Question

I have a datetime string as such 14/04/2014 4:57:16 PM and I am using carbon datetime to work on it.

However as soon as I try to do this

$dt = Carbon::createFromTimestampUTC($encDateTime);

However I am getting parse errors : DateTime::__construct(): Failed to parse time string (@14/04/2014 5:03:45 PM ) at position 3 (/): Unexpected character.

Udpate : I tried doing this :

$date = DateTime::createFromFormat('d/m/Y H:i A', $encDateTime);
dd($date->format('Y-m-d H:i:s'));

and I get the following error Call to a member function format() on a non-object

Can you please help me out with this?

Thanks

Answer 1

Your date string contains a space at the end - that's why DateTime::createFromFormat() fails to parse it. To remove the extra whitespace from the beginning and/or end, you could use trim().

Also, you were originally using H, which is the 24-hour format with leading zeroes. In this case, it looks like you have a 12-hour format, so use g instead (h would work, too).

The following should work:

$date = DateTime::createFromFormat('d/m/Y g:i:s A', trim($encDateTime));

When you receive such errors, always var_dump() the values. That way, you can check if the variable contains what you think it does.

Answer 2

The static method createFromFormat from DateTime returns NULL when there is a parse error. The format that was given (d/m/Y H:i A) was wrong. Hence the error "Call to a member function format() on a non-object".

You can create DateTime objects from non-standard timestrings like this:

$time = '14/04/2014 4:57:16 PM';
$date = Carbon\Carbon::createFromFormat('d/m/Y g:i:s A', $time);

The different format characters available and their explanations can be found in the documentation for date().

Answer 3

I don't know anything about Carbon, but this works. You were using a two digit (H) instead of h (edit: g is the same exact thing) in your createFromFormat method:

$encDateTime = "14/04/2014 4:57:16 PM";

$date1 = DateTime::createFromFormat('d/m/Y h:i:s A', trim($encDateTime));
echo $date1->format('Y-m-d H:i:s');

result:

2014-04-14 16:57:16

Answer 4

just use laravel date function as:

$productsales=DB::table('tbl_trans')   
     ->leftjoin('tbl_product','tbl_product.prod_id','=','tbl_trans.product_id')  
     ->select(DB::raw('count(product_id) as quant'),'product_id','tbl_product.name','tbl_product.code','tbl_product.price')    
     ->groupBy('product_id','code','name','price')    
     ->whereDate('tbl_trans.created_at','2017-07-29')  
     ->get();


   return view('reports.productsales',compact('productsales'));
