php按字符切割字符串

Question

  

可能重复：
  php string function to get substring before the last occurrence of a character

我有字符串

'storage/product/home_decor/living_room/livingroom/7ce3da03b6854283bdd0b8e33b3e556a.11.09.2012.03.42.33.jpg'

如何用/删除最后一个字符串？

我希望我的输出是

'storage/product/home_decor/living_room/livingroom/'

Answer 1

如果您想保留最后一个/结果，请使用以下代码：

$string = 'storage/product/home_decor/living_room/livingroom/7ce3da03b6854283bdd0b8e33b3e556a.11.09.2012.03.42.33.jpg';
$min = substr($string, 0, strrpos($string, '/') + 1);
echo $min; //output : storage/product/home_decor/living_room/livingroom/

Answer 2

substr($string, 0, strrpos($string, '/'));
