小编bco*_*sca的帖子

我需要你的辅助相关的PHP.在PHP中,我想只允许html <img>标签,我尝试了php的内置功能,strip_tags()但它没有给我我需要的输出.例如,在下面的代码中strip_tags()允许img标签,但同时包含文本.

$img = "<img src='/img/fawaz.jpg' alt= ''> <br /> <p> This is a detailed paragraph about Fawaz and his mates.</p>";
echo strip_tags($img , "<img>");

什么是仅允许<img>或仅来自函数或变量的任何标记的正确方法.任何帮助都值得赞赏.

谢谢

有人可以在java中分享一个程序，它执行以下操作。如果给定以下集合作为输入，

a={1,2,3,8,9,10}
b={1,2,3,4,5}
c={4,5,7}
d={5,6,7}
e={6,7,8,9,10}

和

U={1,2,3,4,5,6,7,8,9,10}

程序将找到集合的所有组合，并找出集合在一起具有 U 的所有元素的最小集合数。

在上面的例子中，最小数是2。集合b和e一起覆盖了所有的U。所以基本上，这是一个集合覆盖问题。在集合覆盖问题中，我们给定了一个宇宙 U，使得|U|=n，并且集合S1,……,Sk是 U 的子集。一个集合覆盖是一些集合的集合 C，S1,……,Sk它的并集是整个宇宙 U。此外，我们必须最小化套装的成本。

嗨,我只是有一个简单的问题:在您的网站上工作时,建议传递变量的方法是什么. - 获取,发布,会话,cookie,隐藏字段,...

上面的代码是一个javascript函数.我需要在else部分初始化PHP变量

function validate() {
    if(document.loginForm.vuser_login.value==""){
        alert("Login Name name cannot be empty");
        document.loginForm.vuser_login.focus();
        return false;
    } else if (document.loginForm.vuser_password.value=="") {
        alert("Password cannot be empty");
        document.loginForm.vuser_password.focus();
        return false;
    } else {
        //Here i need to initialise PHP variable ......
        return true;
    }
}

我从http://www.freereviewscript.com下载了免费评论脚本

其中一个文件是编码的,我想确保它没有任何恶意!任何帮助将非常感激!谢谢!!
