preg_replace改写preg_replace_callback的问题
原代码如下:

<br />        $pattern = array(<br />            '/<!--[^>|\n]*?({.+?})[^<|{|\n]*?-->/', // 替换smarty注释<br />            '/<!--[^<|>|{|\n]*?-->/',               // 替换不换行的html注释<br />            '/(href=["|\'])\.\.\/(.*?)(["|\'])/i',  // 替换相对链接<br />            '/((?:background|src)\s*=\s*["|\'])(?:\.\/|\.\.\/)?(images\/.*?["|\'])/is', // 在images前加上 $tmp_dir<br />            '/((?:background|background-image):\s*?url\()(?:\.\/|\.\.\/)?(images\/)/is', // 在images前加上 $tmp_dir<br />            '/{nocache}(.+?){\/nocache}/ise', //无缓存模块<br />            );<br />        $replace = array(<br />            '\1',<br />            '',<br />            '\1\2\3',<br />            '\1' . $tmp_dir . '\2',<br />            '\1' . $tmp_dir . '\2',<br />            "'{insert name=\"nocache\" ' . '" . $this->_echash . "' . base64_encode('\\1') . '}'",<br />            );<br /><br />        return preg_replace($pattern, $replace, $source);<br />
