Http_build_query

(PHP 5)

http_build_query?—? request string after generating Url-encode

Description

string? Http_build_query? (? array? $formdata ? [,? string? $numeric _prefix ?] )

Generates a Url-encode request string using the given array of associations (or subscripts). Parameters? formdata? can be an array or an object that contains properties. One? formdata? An array can be a simple one-dimensional structure or an array of arrays (which in turn can contain other arrays). What if a numeric subscript is used in the underlying array? numeric_prefixparameter, this parameter value will be prefixed with the number subscript element in the underlying array. This is to get a valid variable name when PHP or other CGI programs decode the data later.

Note:

Use the arg_separator.output? to separate the parameters.

Example #1? http_build_query ()? Using the example

$data? =?array (' foo '='bar '),
?????????????? ' Baz ' = ' boom ' ,
?????????????? ' cow ' = ' Milk ' ,
?????????????? ' php ' = ' Hypertext?processor ' );
??????????????
Echo? Http_build_query ($data);? //?foo=bar&baz=boom&cow=milk&php=hypertext+processor
?>

Example #2? http_build_query ()? Use the element with a number subscript

$data? =?array (' foo ',?' Bar ',?' Baz ',?' boom ',?' cow '?=>?' Milk ',?' php '?=' Hypertext?processor ');
??????????????
Echo? Http_build_query ($data );

?
echo? Http_build_query ($data,? ' Myvar_ ' );

?>

=======================================================================================

A simple understanding of these two functions

Parse_str is to convert a URL into an array after the argument

Array Parse_str (Url,arr)

Parse_url is to parse a full URL into an array

Array parse_url (string url)

Http_build_query is the conversion of an array into a URL, followed by a string of arguments that are automatically urlencode processed

String Http_build_query (Array formdata [, String Numeric_prefix])

Add subscript to the array without specifying a key or a key as a number
