PHP将逗号,空格,回车, |,分隔的字符串转换为数组

本程序用来获取一个网站的meta keyword信息,keyword通常为逗号,空格,|,分割,本函数可以把每个关键词存在数组里

<?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));
