I tried to use the function number_formatof PHPbut I could not do it correctly. How can I solve this problem ?

Answer 1

You can elaborate as follows:

function formata_valor($valor){
    if($valor!=NULL){
        echo number_format($valor, 0, ',', '.');
    } else {
        echo "Nenhum valor foi preenchido.";
    }
}
echo formata_valor("10000"); // output 10.000
