[dsp77]

Hello, i have the code below and i need to have all results in a variable as a string, inside the loop they are displayed how i want but outside will echo the last result.  Thank You.

foreach($_POST as $key=>$value){
	if (is_numeric($value)) {
			$valoare = "$value,";

		}
}
echo $valoare;

[phppaper]

foreach($_POST as $key=>$value){

 

$valoare .= $value.",";

 

}

echo $valoare;
