blank space gets automatically replaced by underscore

I have the following php code in my input field:

<input type="submit" name='<?php echo $row["date"];?>' value="send">

a var_dump($row["date"]) shows the data is a string like so:

string '2015-10-03 19:01:47' (length=19)

Why then, when I post this form, does the blank space get automatically replaced by an underscore and how can I avoid that?

var_dump($_POST):

array (size=1)
'2015-10-03_19:01:47' => string 'send' (length=4)

As @arkascha has explained in his comment.

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

So it is not possible to have space as a name. You asked how to avoid this one? Simple, just don't use the date as the name of the input. You can have hidden input field that hold the date value.

<input type="hidden" name='date' value='<?php echo $row["date"];?>'>
<input type="submit" name='submit' value="send">

Alternatively, you can use <button>

<button type="submit" name="submit" value="<?php echo $row["date"]; ?>">Submit</button>

You can use str_replace to get the desired behavior:

<?php
$send = '2015-10-03_19:01:47';
echo str_replace("_"," ",$send);
?>

OUTPUT:

2015-10-03 19:01:47
