php写的将逗号、空格、回车分隔的字符串转换为数组的函数

<?php
/**
* transform ' hello, world !' to array('hello', 'world')
* url: http://www.jiaochengji.com
* date: 2013/2/17
*/
function strsToArray($strs) {
$result = array();
$array = array();
$strs = str_replace('，', ',', $strs);
$strs = str_replace("n", ',', $strs);
$strs = str_replace("rn", ',', $strs);
$strs = str_replace(' ', ',', $strs);
$array = explode(',', $strs);
foreach ($array as $key => $value) {
if ('' != ($value = trim($value))) {
$result[] = $value;
}
}
return $result;
}
//test http://www.jiaochengji.com
$strs = 'Code is poetry! WTF!';
var_dump(strsToArray($strs));
?>
