PHP一直在逃避我的表单的输入(在我的'后面添加\)

Question

所以基本上当我输入带有撇号的东西时,比如约翰的自行车,它会回应约翰的自行车.代码如下:

<?php
$searchname = $_POST["name"] ;
echo "$searchname";

我的表单使用POST方法.有没有办法阻止这个？

另外,为了使输入大小写不敏感,我将如何进入这一部分？

$searchsport = $_POST['sport'];
$sportarray = array(
"Football" => "Fb01",
"Cricket" => "ck32",
"Tennis" => "Tn43",
);
if(isset($sportarray[$searchsport])){
header("Location: ".$sportarray[$searchsport].".html");
die;
}
    //what code is needed to make the if statement work? I've looked up some weird ways such as using array_change_key_case (which I clearly don't understand).

这很可能是因为你打开了魔法引号,试试这个:

if (get_magic_quotes_gpc())
{
  $searchname = stripslashes($_POST["name"]);
  echo "$searchname";
}
else
{
  $searchname = $_POST["name"];
  echo "$searchname";
}

实际上,您可以创建一个函数,而不是自动为您执行此操作:

function fixIt($str)
{
    if (is_array($str))
    {
        foreach ($str as &$value)
        {
            $value = fixIt($value);
        }

        return $str;
    }
    else
    {
        return stripslashes($str);
    }    
}

然后你可以简单地做:

$searchname = fixIt($_POST["name"]);
echo $searchname;

注意:您也可以禁用php.ini中的丑陋魔术引号,因为它们存在问题,并且正确地弃用了PHP的未来版本.
