สอบถามทีครับว่าผมเขียน Function มา 2 ตัวครับ ทั้ง 2 ตัวมี preg_replace แต่ไม่สามารถอ่านค่าออกมาได้ครับแนะนำทีครับ

    Public function bbcodes ($text) {
        $str_search = array(
            "#\r\n|\r|\n|\n\r#is",
            "#\[p\](.+?)\[\/p\]#is",
            "#\[b\](.+?)\[\/b\]#is",
            "#\[i\](.+?)\[\/i\]#is",
            "#\[s\](.+?)\[\/s\]#is",
            "#\[u\](.+?)\[\/u\]#is",

            "#\[url\](.+?)\[\/url\]#is",

    }
