Swap a dot for a comma and add a dot

Question

How do I add the comma to the decimal place and the dot to the thousands.

Example:

$pagamento = R$ 1000.50;

/* trecho a fazer a operação */

echo $pagamento; //saída: "R$ 1.000,50"

Answer 1

Use the function number_format for its amendment

$valor = 1000.50;
$valor = number_format($valor, 2 , ",", ".");

Answer 2

Dude

$moeda = 'R$ 1.550,52';

$valor = preg_replace('/[^0-9]/', '', $moeda);    
$valor = bcdiv($valor, 100, 2);
$valor = strtr($valor, '.', ',');

echo $valor;

Or if you want to be separated by .

$moeda = 'R$ 1.550,52';

$valor = preg_replace('/[^0-9]/', '', $moeda);    
$valor = bcdiv($valor, 100, 2);
$valor = strtr($valor, ',', '.');

echo $valor;
