Is there any way to dynamically put a mask in php?

I would like to put masks in different fields, all via php, for example:

cnpj - "##.###.###/####-##"

Cpf - "###.###.###-##"

zip code - "#####-###"

telephone - "(##)####-####"

date - "##/##/####"

I don’t want to use jquery, or javascript masks, I would like to do it in php anyway, because I want to use these masks to format data coming from the database.

    The expression "dynamically" is usually used when we refer to a change in HTML after it is already loaded on the page, so what you want is to mask before the HTML presentation ;)

  • I think "waste" doing this in server-side, will create an unnecessary work, which could be easily transferred to the customer, in your browser, but that’s just my opinion.

php function that puts format the fields by putting masks.

function Mask($mask,$str){

    $str = str_replace(" ","",$str);

    for($i=0;$i<strlen($str);$i++){
        $mask[strpos($mask,"#")] = $str[$i];
    }

    return $mask;

}

------------------------ function call ----------------------------

$cnpj = '17804682000198';
echo Mask("##.###.###/####-##",$cnpj).'<BR>';

$cpf = '21450479480';
echo Mask("###.###.###-##",$cpf).'<BR>';

$cep = '36970000';
echo Mask("#####-###",$cep).'<BR>';

$telefone = '3391922727';
echo Mask("(##)####-####",$telefone).'<BR>';

$data = '21072014';
echo Mask("##/##/####",$data);

You can use vsprintf as follows:

function format($mask,$string)
{
    return  vsprintf($mask, str_split($string));
}

Example:

$cnpjMask = "%s%s.%s%s%s.%s%s%s/%s%s%s%s-%s%s";
echo format($cnpjMask,'11622112000109');
11.622.112/0001-09
