Question: thanks for your help in advance, noob here.

So, i have this error div of a form.

```
<div><?php echo $error; ?></div>

```

I'm trying to validate an email with php, but i want its error to change depending of the language selected by the user. I have another two php files with arrays with the translated text. What i'm tryng to do is to echo the error that contains the echo for the array variable so it can be interpreted as multilingual text in the html. I know that you can't echo an echo, but i need a workaround for this. Here is the php part. 

```
<?php

$error = '';

if ($_POST) {

if (filter_var($_POST['mail'], FILTER_VALIDATE_EMAIL) === false) {

    $error .= '<?php echo $lang["EMAIL_INVÁLIDO"]; ?>';

};

if ($error != "") {

    $error = '<p>' . $error . '</p>';

};

};

?>

```

Thanks!

Answer: 
instead of direct echo, try assigning it to the variable and then echo the variable.

```
<?php
$error = '';
if ($_POST) {
    if (filter_var($_POST['mail'], FILTER_VALIDATE_EMAIL) === false) {
        $error .= $lang["EMAIL_INVÁLIDO"]; 
    };
    if ($error != "") {
        $error = '<p>' . $error . '</p>';
    };
};
?>

```
As you say, you can´t echo an echo because PHP is server-side. You must put your echo after you now the final value of error:

```
 <?php

$error = '';

if ($_POST) {

if (filter_var($_POST['mail'], FILTER_VALIDATE_EMAIL) === false) {

    $error .= '$lang["EMAIL_INVÁLIDO"]';

};

if ($error != "") {

    $error = '<p>' . $error . '</p>';

};

echo $error;
};

?>

```
