Why is it wrong to put a space at the end of a sentence?

When I select a record from a ListPicker, if it contains a space after the last word, it does not show it to me on the screen:

Ex: Antonio Navas Espejo

If after Mirror I leave a space, I would give error.

Here is the code I use:

php:

if ($boton == "btnVerarticulos"){

//$articulo = $_GET['articulo'];

$query="select * from articulos ORDER BY articulo ASC";

$result = mysql_query($query);

  while($linea = mysql_fetch_object($result))

      echo $linea->articulo."#";

  echo "^";

}

$articulo = $_POST['articulo'];

$query="select * from articulos where articulo like '$articulo'";

$result = mysql_query($query);

  // Obtém o resultado de uma linha como um objeto

  while($linea = mysql_fetch_object($result)) {

      echo $linea->articulo."#";

  echo $linea->cantidad."#";

  echo $linea->referencia."#";

  echo $linea->ubicacion."#";

  }

  echo "^";

try this script https://puravidaapps.com/mysql.php instead

Thanks Taifun, I have finally opted for the trim () function:

// String example with leading and trailing whitespace $ String = "sentence sentence phrase"; $ String_format = trim ($ string); Echo "The original string is this: $ string." 'And the formatted one is this: $ string_formatted.

the php mysql API is deprecated, you should use mysqli instead...

Why shouldn't I use mysql_* functions in PHP?
