How to modify and support PHP7 in ecshop
ecshop
ecshop修改php的方法：首先将mysql扩展的使用替换掉，改为使用mysqli或pdo；然后更改“cls_image.php”的“gd_version()”方法，将这个方法改为静态方法；最后去除使用类名的构造函数。
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()
{
....
}Copy after login
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 = '', $bgcolor='')
{
$gd = $this->gd_version(); //获取 GD 版本。0 表示没有 GD 库，1 表示 GD 1.x，2 表示 GD 2.x
。。。
}Copy after login
将其改为：
function make_thumb($img, $thumb_width = 0, $thumb_height = 0, $path = '', $bgcolor='')
{
$gd = self::gd_version(); //获取 GD 版本。0 表示没有 GD 库，1 表示 GD 1.x，2 表示 GD 2.x
。。。
}Copy after login
还有includes/lib_base.php文件的gd_version函数，改为：
function gd_version()
{
include_once(ROOT_PATH . 'includes/cls_image.php');
return cls_image::gd_version();
}Copy after login
其他文件代码在调用时，最好改为调用lib_base文件的gd_version的函数。可以搜索更改。
（3）更改includes/lib_main.php文件的get_dyna_libs函数，该第一行的代码：
function get_dyna_libs($theme, $tmp)
{
$ext = end(explode('.', $tmp));
。。。
}Copy after login
更改为：
function get_dyna_libs($theme, $tmp)
{
$tmp_ext = explode('.', $tmp);
$ext = end($tmp_ext);
}Copy after login
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。
