从日期和月份更改位置将字符串转换为日期

I am working on following issue in PHP. I have these variables:

$fecha = "01-07-2017";

$hora = "11:30";

Now I want to create a date variable with format Y-m-d H:i.

For that I am using following code:

$newDate = date("Y-m-d H:i", strtotime($fecha.' '.$hora));

But I am getting the output:

echo $newDate = 2017-01-07 11:30

I need it to be: 2017-07-01 11:30

What am I doing wrong?

Use the DateTime API to parse your string(s) initially

$dt = DateTime::createFromFormat('d-m-Y H:i', $fecha.' '.$hora);
$newDt = $dt->format('Y-m-d H:i');

Change your code to:

$newDate = date("Y-d-m H:i", strtotime($fecha.' '.$hora));

Notice that I just switched around 'h' & 'd' in the date function.
