Delete Line with email

Question

There is a form in PHP, that companies use to post vacancies.

Sometimes they put inside the textarea something like:

Send vacancy to [email protected]

I would like to VIA PHP, delete all lines (only the line, in full) that contained an email. Follow the example below:

Vacancy for Mason

Salario: XXX

City: XXXX

Send e-mail with resume to [email protected]

Task: XXXXXXXXXXXXXXXXXX

You should stay:

Vacancy for Mason

Salario: XXX

City: XXXX

Task: XXXXXXXXXXXXXXXXXX

Remembering that it will not always be Send resume to [email protected]. Sometimes they write differently, such as sending data to, send an email with if data. At last.

Answer 1

Explode the text area on different lines.
Traverse the resulting array by printing only lines that have no email

$linhas = explode("\n", $textarea);
foreach ($linhas as $linha) {
    // teste básico para presença de email
    if (!preg_match('/[a-z0-9]+@[-a-z0-0]+\.[a-z]+/', $linha)) {
        echo $linha;
    }
}

Answer 2

The question is very poorly formulated, so you received so many negatives, I hope you edit it so that people will come back to you positive. But from what I understand, you want to filter the email from the textarea field, to do this, there are two ways, you can block email typing using javascript:

<script>
    function removerEmail(input)
    {
       input.value = input.value.replace(/(.*)[a-z0-9\.\_\-]+@[a-z0-9\.\_\-]+\.[a-z]+(.*)/gi,'');
    }
</script>

Html:

<textarea onkeyup="removerEmail(this)" onkeypress="removerEmail(this)">
</textarea>

Take this example.

And in PHP using a filter for the line that contains the email:

function filterEmail($text)
{
   return preg_replace('/(.*)[a-z0-9\.\_\-]+@[a-z0-9\.\_\-]+\.[a-z]+(.*)/i','', $text);
}

Answer 3

I’m not sure where to use it, but when I need to inhibit the user from writing, posting, sending or whatever with his email, I use a preg_replace with specifications like the one below. and then the typed email is replaced by [The E-MAIL CANNOT BE DISPLAYED]

$text = preg_replace('/([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)/','[O E-MAIL NAO PODE SER EXIBIDO]', $text);
