php正则表达式匹配分隔符 php数组输出的时候.用逗号分隔..

php正则表达式匹配分隔符

//php正则用任意分隔符（" " "," "/" "!"）分割字符串成数组
$str = "Hello world!Hello,world!Hello/world"
$str = preg_split("/[s,/!] /", $str)
echo 

print_r($str)
?>运行输出为：
Array
(
    [0] => Hello
    [1] => world
    [2] => Hello
    [3] => world
    [4] => Hello
    [5] => world
)

希望对你有所帮助。
