preg_split（正则表达式）

Question

如何在Symfony表单中将Array类型的数据作为TextArea获取？ ：

我试过了：

$suggest = $table->getSuggestion;

/* its format in database is : 
s:378:"# first_suggest
# second_suggest
# third_suggest 
*/

$suggest = preg_split("/# (.*)[\n\r]*/", $suggest, null, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
$table->setSuggestion($suggest);

＆安培;所以它在textarea字段中显示为：

#first suggestion 
#second suggestion
#third suggestion

但在数据库中似乎如下：

a:8:{i:0;s:32:"first_suggest
";i:1;s:47:"second_suggest
";i:2;s:45:"third_suggest";}

表示：

array:42 [▼
  0 => "first_suggest\r"
  1 => "second_suggest \r"
  2 => "third_suggest \r"
]

而不是：

a:8:{i:0;s:32:"first_suggest";i:1;s:47:"second_suggest";i:2;s:45:"third_suggest";}

＆安培;我不知道这里的问题在哪里，你能帮我吗？！
