PHP 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') 
*/ 
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 
$strs = 'Code is poetry! WTF!'; 
var_dump(strsToArray($strs));
