代码当中加了几个方法,用于支持事务。

(2)更改cls_image.php的gd_version()方法,将这个方法改为静态方法,并且所有调用此方法的地方,都改为静态调用。

PHP5.6开始,已经不支持不兼容的上下文调用方法,并且产生 E_DEPRECATED 错误(以前是 E_STRICT)。

更改如下:

1

2

3

4

5

6

7

8

9

10

11

includes/cls_images.php,(gd_version方法体添加static关键字)

/**

* 获得服务器上的 GD 版本

*

* @access public

* @return int 可能的值为0,1,2

*/

static function gd_version()

{

....

}

登入後複製

在好几处调用此方法的地方都改为静态调用,比如includes/cls_images.php的好几个方法在调用时使用类对象调用:

1

2

3

4

5

function make_thumb($img, $thumb_width = 0, $thumb_height = 0, $path = &#39;&#39;, $bgcolor=&#39;&#39;)

{

$gd = $this->gd_version(); //获取 GD 版本。0 表示没有 GD 库,1 表示 GD 1.x,2 表示 GD 2.x

。。。

}

登入後複製

将其改为:

1

2

3

4

5

function make_thumb($img, $thumb_width = 0, $thumb_height = 0, $path = &#39;&#39;, $bgcolor=&#39;&#39;)

{

$gd = self::gd_version(); //获取 GD 版本。0 表示没有 GD 库,1 表示 GD 1.x,2 表示 GD 2.x

。。。

}

登入後複製

还有includes/lib_base.php文件的gd_version函数,改为:

1

2

3

4

5

function gd_version()

{

include_once(ROOT_PATH . &#39;includes/cls_image.php&#39;);

return cls_image::gd_version();

}

登入後複製

其他文件代码在调用时,最好改为调用lib_base文件的gd_version的函数。可以搜索更改。

(3)更改includes/lib_main.php文件的get_dyna_libs函数,该第一行的代码:

1

2

3

4

5

function get_dyna_libs($theme, $tmp)

{

$ext = end(explode(&#39;.&#39;, $tmp));

。。。

}

登入後複製

更改为:

1

2

3

4

5

function get_dyna_libs($theme, $tmp)

{

$tmp_ext = explode(&#39;.&#39;, $tmp);

$ext = end($tmp_ext);

}

登入後複製

end方法的接受的参数必须是引用传递值,这里使用了explode方法返回值,不可以直接套用。

(4)includes/cls_template.php代码:

preg_replace方法,自PHP5.5开始 /e修饰符已经废弃,所以要使用preg_replace_callback代替。此代替有多处:

fetch_str方法:

1

2

3

4

5

6

7

8

9

fetch_str($source)

{

。。。

return preg_replace_callback("/{([^\}\{\n]*)}/",&#39;self::select_replace&#39;, $source);

}

//新增的方法

private function select_replace($matches){

return $this->select($matches[1]);

}

登入後複製

select方法:

1

2

3

4

5

6

7

8

9

10

11

12

function select($tag)

{

。。。

$pregReplace = preg_replace_callback("/(\&#39;\\$[^,]+)/" , function($matches){

return stripslashes(trim($matches[1],&#39;\&#39;&#39;));

}, var_export($t, true));

。。。

}

smarty_prefilter_preCompile方法:

$source = preg_replace_callback($pattern, function($matches){

return &#39;{include file=&#39;.strtolower($matches[1]). &#39;}&#39;;

}, $source);

登入後複製

(5)将所有类的构造函数,都去除使用类名的构造函数,保留__construct():

涉及此改动的超多,用搜索一一找到并改动吧……这个就不列举了。
