php中url问题,PHP解析URL并失去URL中的参数

PHP解析URL并得到URL中的参数

//例举一个URL格式的字符串:

$str = http://test.com/testdir/index.php?param1=10&param2=20&param3=30&param4=40&param5=50&param6=60;

//1 用parse_url解析URL,此处是$str

$arr = parse_url($str);

var_dump($arr);

//2 将URL中的参数取出来放到数组里

$arr_query = convertUrlQuery($arr[query]);

var_dump($arr_query);

//3 将 参数数组 再变回 字符串形式的参数格式

var_dump(getUrlQuery($arr_query));

/**

* Returns the url query as associative array

* @param string query

* @return array params

*/

function convertUrlQuery($query)

{

$queryParts = explode(&, $query);

$params = array();

foreach ($queryParts as $param)

{

$item = explode(=, $param);

$params[$item[0]] = $item[1];

}

return $params;

}

function getUrlQuery($array_query)

{

$tmp = array();

foreach($array_query as $k=>$param)

{

$tmp[] = $k.=.$param;

}

$params = implode(&,$tmp);

return $params;

}

?>

输出结果：

array (size=4)

scheme => string http (length=4)

host => string test.com (length=8)

path => string /testdir/index.php (length=18)

query => string param1=10&param2=20&param3=30&param4=40&param5=50&param6=60 (length=59)

array (size=6)

param1 => string 10 (length=2)

param2 => string 20 (length=2)

param3 => string 30 (length=2)

param4 => string 40 (length=2)

param5 => string 50 (length=2)

param6 => string 60 (length=2)

string param1=10&param2=20&param3=30&param4=40&param5=50&param6=60 (length=59)
