轉換PHP的eregi到的preg_match

Question

我不知道如何定價套餐這個錯誤

Warning: preg_match(): Unknown modifier '[' in 

我的代碼是

while(list($k,$v)=each($con2)) { 
    $patt="($this->block_start_word|$this->block_end_word)[[:blank:]]*([0-9a-zA-Z\_]+)[[:blank:]]*$this->block_end_delim(.*)"; 
    if (eregi($patt,$v,$res)) { 

我想更新eregi的PHP版本的preg_match和我試試這個

hile(list($k,$v)=each($con2)) { 
    $patt="($this->block_start_word|$this->block_end_word)[[:blank:]]*([0-9a-zA-Z\_]+)[[:blank:]]*$this->block_end_delim(.*)"; 
    if (preg_match($patt,$v,$res)) {

你忘了正則表達式的分隔符，所以只需改變它：

if (preg_match($patt,$v,$res)) { 

到：

if (preg_match("/" . $patt . "/",$v,$res)) {
