[PHP]Only variables should be passed by referen

问题：

Strict Standards: Only variables should be passed by reference in C:\MyWeb\lib\cls_template.php on line 406

第406行：$tag_sel = array_shift(explode(' ', $tag));

解决办法1：

5.3以上版本的问题，应该也和配置有关 只要406行把这一句拆成两句就没有问题了

$tag_sel = array_shift(explode(' ', $tag));

改成：

$tag_arr = explode(' ', $tag);

$tag_sel = array_shift($tag_arr);  

因为array_shift的参数是引用传递的，5.3以上默认只能传递具体的变量，而不能通过函数返回值  

 

解决办法 2 ：

修改配置： error_reporting = E_ALL | E_STRICT

If you have access to php.ini check if error_reporting option includes E_STRICT error level. If so, remove it. If you don't have access to php.ini add error_reporting(error_reporting() & ~E_STRICT); in your application code (ex. main PHP entry file).
