ecshop支持PHP7的修改方法

(1)将mysql扩展的使用替换掉,改为使用mysqli或pdo(推荐使用mysqli):

推荐:《ECShop教程

从php5.5开始,mysql扩展将废弃了。 具体更改的文件在于includes/cls_mysql.php。这是个不小的工程,文件代码太长……

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:

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()
{
....
}
登录后复制

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:

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
。。。
}
登录后复制

将其改为:

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
。。。
}
登录后复制

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

function gd_version()
{
include_once(ROOT_PATH . &#39;includes/cls_image.php&#39;);
return cls_image::gd_version();
}
登录后复制

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:

function get_dyna_libs($theme, $tmp)
{
$ext = end(explode(&#39;.&#39;, $tmp));
。。。
}
登录后复制

更改为:

function get_dyna_libs($theme, $tmp)
{
$tmp_ext = explode(&#39;.&#39;, $tmp);
$ext = end($tmp_ext);
}
登录后复制

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:

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]);
}
登录后复制

select方法:

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);
登录后复制

(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。
