Php 将osComerce中的ereg_替换功能更改为preg_替换功能

我正试图将一个旧的osCommerce站点移动到一个新的服务器上，但对一个不推荐使用的功能有疑问。我需要把ereg换成preg_match

这是原始代码：

function _filter_save_image ($products_delete_image) {
    $products_delete_image = htmlspecialchars(stripslashes($products_delete_image));
    $products_delete_image = ereg_replace('&lt;img ', '', $products_delete_image); // Remove: <img
    $products_delete_image = ereg_replace('src=', '', $products_delete_image); // Remove: src=
    $products_delete_image = ereg_replace('&quot;', '', $products_delete_image); // Remove: "
    $products_delete_image = ereg_replace('/&gt;', '', $products_delete_image); // Remove: />
    $products_delete_image = ereg_replace(HTTP_SERVER.DIR_WS_CATALOG_IMAGES, '', $products_delete_image); // Remove: absolute path
        return $products_delete_image;
}

function\u filter\u save\u image（$products\u delete\u image）{
$products_delete_image=htmlspecialchars（条纹斜杠（$products_delete_image））；
$products_delete_image=ereg_replace（'img'，''，$products_delete_image）；//删除：
$products_delete_image=ereg_replace（HTTP_SERVER.DIR_WS_CATALOG_IMAGES，，$products_delete_image）；//删除：绝对路径
返回$products\u delete\u图像；
}

这是我修改代码的尝试：

function _filter_save_image ($products_delete_image) {
    $products_delete_image = htmlspecialchars(stripslashes($products_delete_image));
    $products_delete_image = preg_replace('/\&lt;img/', '', $products_delete_image); // Remove: <img
    $products_delete_image = preg_replace('/src=/', '', $products_delete_image); // Remove: src=
    $products_delete_image = preg_replace('/\&quot;/', '', $products_delete_image); // Remove: '
    $products_delete_image = preg_replace('/\&gt;/', '', $products_delete_image); // Remove: />
    $products_delete_image = preg_replace('/\/HTTP_SERVER.DIR_WS_CATALOG_IMAGES/', '', $products_delete_image); // Remove: absolute path
        return $products_delete_image;
}

function\u filter\u save\u image（$products\u delete\u image）{
$products_delete_image=htmlspecialchars（条纹斜杠（$products_delete_image））；
$products_delete_image=preg_replace（'/\img/'，'$products_delete_image）；//删除：
$products\u delete\u image=preg\u replace（'/\/HTTP\u SERVER.DIR\u WS\u CATALOG\u IMAGES/，''$products\u delete\u image）；//删除：绝对路径
返回$products\u delete\u图像；
}

我现在没有收到错误，但它也不起作用。

无需逃避

   function _filter_save_image ($products_delete_image) {
            $products_delete_image = htmlspecialchars(stripslashes($products_delete_image));
            $products_delete_image = preg_replace('/&lt;img/', '', $products_delete_image); // Remove: <img
            $products_delete_image = preg_replace('/src=/', '', $products_delete_image); // Remove: src=

            $products_delete_image = preg_replace('/HTTP_SERVER.DIR_WS_CATALOG_IMAGES/', '', $products_delete_image); // Remove: absolute path
                return $products_delete_image;

$products_delete_image=preg_replace（'/HTTP_SERVER.DIR_WS_CATALOG_IMAGES/'，'$products_delete_image）；//删除：绝对路径
返回$products\u delete\u图像；
}

为什么不升级osCommerce版本？在我们开发新网站的过程中，对一家高度定制的商店来说，改变一小块像osCommerce这样的东西通常不是一个好主意。这是一个临时的解决方案。但是同意了，他们急需升级！非常感谢。我离得越来越近了，我仍然以/在开始和结束结束，虽然这以前没有发生过，所以我仍然在做一些错误的事情。。。谢谢你的帮助！
