You can use strpos()and substr()for this. See
为此，您可以使用strpos()和substr()。看
- http://php.net/strpos
$string = substr($string, 0, strpos($string, ', ddd'));
- http://php.net/strpos
$string = substr($string, 0, strpos($string, ', ddd'));
Alternate approach using explode:
使用爆炸的替代方法：
$arr = explode(',', $string);
$string = implode(',',array_slice($arr, 0, 3);

If you don't know exactly the number chars to count I would suggest an ImplodeExplodelike this:
如果您不确切知道要计算的字符数，我会建议ImplodeExplode这样的：
$string = "aaa, bbb, ccc, ddd, eee, fff";
$arr = explode(',' , $string);
$out = array();
for($i = 0; $i < 3; $i++)
{
$out[] = $arr[$i];
}
$string2 = implode(',', $out);
echo $string2; // output is: aaa, bbb, ccc
