Question

I am passing this array from one function to another


    function componentBuildRoute(&$query)
    {
        $segments = array();
        $segments[] = $var...
        ...
        $str = serialize($segments);
        $str = urlencode($str);
        $segments[] = $str;

//if I do a pre print_r for $segments[];
//THIS PRINTS
//**SERIALIZED:
//Array
//(
//    [page] => mostrar_clasificado
//    [catid] => 3
//    [category_alias] => nuevo
//    [adid] => 3
//    [ad_alias] => 3-way-conector-de-tubos
//    [0] => a%3A5%3A%7Bs%3A4%3A%22page%22%3Bs%3A19%3A%22mostrar_clasificado%22%3Bs%3A5%3A%22catid%22%3Bs%3A1%3A%223%22%3Bs%3A14%3A%22category_alias%22%3Bs%3A5%3A%22nuevo%22%3Bs%3A4%3A%22adid%22%3Bs%3A1%3A%223%22%3Bs%3A8%3A%22ad_alias%22%3Bs%3A23%3A%223-way-conector-de-tubos%22%3B%7D

    return $segments;
    }

 function componentParseRoute( $segments )  
    {
//if I do a pre print_r() for the passed array of $segments[]; 
//*THIS PRINTS

//)**
        $str = end($segments);
        echo "LAST ELEMENT OF PASSED ARRAY STR:

//THIS PRINTS:

//**DECODED ALREADY HOW COME?**
        $testing = array();
        **$testing = unserialize($str);**
        echo "UNSERIALIZED TESTING:";
    print_r($testing);
//THIS PRINTS:
//UNSERIALIZED SEGMENTS: 
//**NO ARRAY!!! (BLANK SPACE AFTER TEXT) NO UNSERIALIZED ARRAY**
//I'LL PRINT THE ARRAY AGAIN TO VERIFY I GOT WHAT I THOUGHT I GOT

echo "SEGMENTS 2:";
    print_r($segments);

//THIS PRINTS:
//SEGMENTS 2:

//Array
//(
//    [0] => mostrar_clasificado

//)
//I AM UNABLE TO **UNSERIALIZED** THE LAST ELEMENT OF THE ARRAY
//any pointers?
//also, as I mentioned before, 
//I don't understand why the urlencoded 
//and serialized 
//element of the array, gets passed to 
//the second function already urldecoded

嘿DOD这段代码正常工作！



function componentBuildRoute(&$query)
{
        $segments = array();
        $str = serialize(
            array(
                "page"=>"mostrar_clasificado",
                "catid"=>"3",
                "category_alias"=>"nuevo",
                "adid"=>"3",
                "ad_alias"=>"3-way-conector-de-tubos"
                )
            );
        $str = urlencode($str);
        $segments[] = $str;
        return $segments;
}
function componentParseRoute( $segments )  
{
        $str = end($segments);
        $testing = array();
        $str = urldecode($str);
        $testing = unserialize($str);
   return $testing;
}

$query = '';

$val = componentBuildRoute(&$query);
print_r($val);
echo "\n";
$val2 = componentParseRoute($val);
print_r($val2);

我无法通过数组段将我传递给第二个函数的字符串反序列化。我在互联网上发现了许多帖子，表明当一个序列化的字符串传递给已传递的数据的核心结构时，即使它看起来完好无损也可能已经改变。我不知道技术性。但是当我做了var_dump（sunserialized_array）时，我得到了错误。

对于我发现的一些信息，我发布了这些链接：
http://www.php.net/manual/en/function.unserialize.php#70884
http://www.php.net/manual/en/function.unserialize.php#40757

我最初的目标是传递一个数组的序列化版本，作为同一数组的字符串元素，以便在第二个函数中进行反序列化和使用。所以我在问题中使用收集的键和数组变量创建了一个字符串（我的问题代码中的数组$ segments），并且我将$ string_to_be_parsed添加到正在传递的数组中。我在第二个函数中检索了$ string_to_parsed = end（$ segments），并且...这里是好的部分使用此函数重新创建数组 parse_str（$ str，$ segments）;

我找到了这个解决方案：Why does unserialize in PHP keep returning false?

所以，我无法对我想要的内容进行反序列化，但我找到了另一种实现目标的方法。
