如果数字不确定，可以用正则替换

$str = "(123,123,123,";
$str = preg_replace('/(\d+),(\d+),(\d+),/', '${1},${2},${3})', $str);

echo $str;

或者

$str = "(123,123,123,";
$str = preg_replace('/\(([\d,]+),/', '(${1})', $str);

echo $str;

$string = "(123,123,123,";
$pattern = "/(\d+\,\d+\,\d+),/";
$replacement = "$1)";
$string = preg_replace($pattern, $replacement, $string);
