yyyy/mm/dd instead expected dd/mm/yyyy format in an HTML form PHP-created-HTML output
I have an HTML-PHP-CSS contact form with a date field:

    <input type="date" name="date" id="cf_input_date"></input>

* The **default value** in this field is the [W3C built-in](https://w3c.org) default: `dd/mm/yyyy`
* The **date-picking pattern** in this field is the W3C built-in default `dd/mm/yyyy`

## My problem

Everything was allegedly fine until I printed this HTML as output to my email box (via PHP).<br>
In my email box, the output pattern for picked dates is the exact opposite of the pattern I already use in the form:

    yyyy/mm/dd

## Things I have tried to solve it

* `dir="ltr"` or `dir="rtl"` attributes-values and `direction: ltr` or `direction: rtl` properties-values don't help in flipping the output
* Various CSS tricks all ended in failure
* Sadly I can't use JavaScript comfortably in this case because the email output appears in a third party email client which doesn't easily allow JavaScript manipulation of the DOM

## My question

How to ensure that my HTML-PHP output is in `dd/mm/yyyy` pattern (as default for the input field itself) instead the "flipped" `yyyy/mm/dd`?
