安装Ecshop首页出现报错：Only variables should be passed by referen

出现下面这就话：

Strict Standards: Only variables should be passed by reference in E:ToolsECShop_V2.7.3_UTF8_release1106uploadincludescls_template.php
on line 418
第418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418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);
（实验过，绝对可行） 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 ： 或则如果这样配置的话： error_reporting = E_ALL | E_STRICT

php.ini中有如下设置：

error_reporting = E_ALL | E_STRICT

 

这是说，显示那些不符合编码规范的警告（coding standards warnings）。

 

Joomla其实是建议取消error的输出，如果出于调试需要，应改为

error_reporting = E_ALL & ~E_NOTICE

 

问题得到解决。

 

下面是错误输出配置的原文：

; This directive informs PHP of which errors, warnings and notices you would like

; it to take action for. The recommended way of setting values for this

; directive is through the use of the error level constants and bitwise

; operators. The error level constants are below here for convenience as well as

; some common settings and their meanings.

; By default, PHP is set to take action on all errors, notices and warnings EXCEPT

; those related to E_NOTICE and E_STRICT, which together cover best practices and

; recommended coding standards in PHP. For performance reasons, this is the

; recommend error reporting setting. Your production server shouldn't be wasting

; resources complaining about best practices and coding standards. That's what

; development servers and development settings are for.

; Note: The php.ini-development file has this setting as E_ALL | E_STRICT. This

; means it pretty much reports everything which is exactly what you want during

; development and early testing.

;

; Error Level Constants:

; E_ALL            - All errors and warnings (includes E_STRICT as of PHP 6.0.0)

; E_ERROR          - fatal run-time errors

; E_RECOVERABLE_ERROR  - almost fatal run-time errors

; E_WARNING        - run-time warnings (non-fatal errors)

; E_PARSE          - compile-time parse errors

; E_NOTICE          - run-time notices (these are warnings which often result

;                   from a bug in your code, but it's possible that it was

;                   intentional (e.g., using an uninitialized variable and

;                   relying on the fact it's automatically initialized to an

;                   empty string)

; E_STRICT          - run-time notices, enable to have PHP suggest changes

;                   to your code which will ensure the best interoperability

;                   and forward compatibility of your code

; E_CORE_ERROR      - fatal errors that occur during PHP's initial startup

; E_CORE_WARNING    - warnings (non-fatal errors) that occur during PHP's

;                   initial startup

; E_COMPILE_ERROR  - fatal compile-time errors

; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)

; E_USER_ERROR      - user-generated error message

; E_USER_WARNING    - user-generated warning message

; E_USER_NOTICE    - user-generated notice message

; E_DEPRECATED      - warn about code that will not work in future versions

;                   of PHP

; E_USER_DEPRECATED - user-generated deprecation warnings

;

; Common Values:

;  E_ALL & ~E_NOTICE  (Show all errors, except for notices and coding standards warnings.)

;  E_ALL & ~E_NOTICE | E_STRICT  (Show all errors, except for notices)

;  E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors)

;  E_ALL | E_STRICT  (Show all errors, warnings and notices including coding standards.)

; Default Value: E_ALL & ~E_NOTICE    ------默认

; Development Value: E_ALL | E_STRICT  ------开发用

; Production Value: E_ALL & ~E_DEPRECATED -- 正式发布用
