原代码如下:

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

原本服务器是php5.2,现在升级成php5.5之后,发现程序出错

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