PHP parses the URL and obtains the parameters in the URL.

  

// Example of a URL string:

$ Str

// 1 use parse_url to parse the URL, which is $ str

$ Arr = parse_url ($ str );

Var_dump ($ arr );

// 2. Extract the parameters in the URL and put them in the array.

$ Arr_query = convertUrlQuery ($ arr ['query']);

Var_dump ($ arr_query );

// 3 change the parameter array back to the string format

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;

}

?>

Output result:

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)
