如题

举例:

$reg = "([^@]+(?=\s))";print_r(preg_split($reg,"@张三 你好我是@李四 的朋友@王五不在家",PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_OFFSET_CAPTURE|PREG_SPLIT_NO_EMPTY));
Copy after login


结果
Array(    [0] => @    [1] =>  你好我是@    [2] =>  的朋友@王五不在家)
Copy after login


希望得到的是
Array(    [0] => @    [1] => 张三    [2] =>  你好我是@    [3] => 李四    [4] =>  的朋友@王五不在家)
Copy after login


查手册看到有个参数PREG_SPLIT_DELIM_CAPTURE :如果这个标记设置了,用于分隔的模式中的括号表达式将被捕获并返回。
但是没有被返回.....


回复讨论(解决方案)

参数位置错了

$reg = "/([^@]+(?=\s))/";print_r(preg_split($reg,"@张三 你好我是@李四 的朋友@王五不在家", -1, PREG_SPLIT_DELIM_CAPTURE |PREG_SPLIT_NO_EMPTY));
Copy after login
Array
(
    [0] => @
    [1] => 张三
    [2] =>  你好我是@
    [3] => 李四
    [4] =>  的朋友@王五不在家
)

非常感?~~~~~~~??了.
