http_build_query
(PHP 5) http_build_query -- Generate URL-encoded query string
Descriptionstring http_build_query ( array formdata [, string numeric_prefix] ) Generates a URL-encoded query string from the associative (or indexed) array provided.
formdata may be an array or object containing properties.
A formdata array may be a simple one-dimensional structure,
or an array of arrays (who in turn may contain other arrays). If numeric indices
are used in the base array and a numeric_prefix is provided,
it will be prepended to the numeric index for elements in the base array only.
This is to allow for legal variable names when the data is decoded by PHP
or another CGI application later on.
Пример 1. Simple usage of http_build_query()
<?php
$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
?>
|
|
Пример 2. http_build_query() with numerically index elements.
<?php
$data
= array(
'foo'
,
'bar'
,
'baz'
,
'boom'
,
'cow'
=>
'milk'
,
'php'
=>
'hypertext processor'
);
echo
http_build_query
(
$data
);
/* Outputs:
0=foo&1=bar&2=baz&3=boom&cow=milk&php=hypertext+processor
*/
echo
http_build_query
(
$data
,
'myvar_'
);
/* Outputs:
myvar_0=foo&myvar_1=bar&myvar_2=baz&myvar_3=boom&cow=milk&php=hypertext+processor
*/
?>

Пример 3. http_build_query() with complex arrays
<?php
$data
= array(
'user'
=>array(
'name'
=>
'Bob Smith'
,
'age'
=>
47
,
'sex'
=>
'M'
,
'dob'
=>
'5/12/1956'
),
'pastimes'
=>array(
'golf'
,
'opera'
,
'poker'
,
'rap'
),
'children'
=>array(
'bobby'
=>array(
'age'
=>
12
,
'sex'
=>
'M'
),
'sally'
=>array(
'age'
=>
8
,
'sex'
=>
'F'
)),
'CEO'
);
echo
http_build_query
(
$data
,
'flags_'
);
?>
|
this will output : (word wrapped for readability)
user[name]=Bob+Smith&user[age]=47&user[sex]=M&user[dob]=5%1F12%1F1956&
pastimes[0]=golf&pastimes[1]=opera&pastimes[2]=poker&pastimes[3]=rap&
children[bobby][age]=12&children[bobby][sex]=M&children[sally][age]=8&
children[sally][sex]=F&flags_0=CEO |
Замечание:
Only the numerically indexed element in the base array "CEO" received a
prefix. The other numeric indices, found under pastimes, do not
require a string prefix to be legal variable names.

Пример 4. Using http_build_query() with an object
<?php
class
myClass
{
var
$foo
;
var
$baz
;
function
myClass
()
{
$this
->
foo
=
'bar'
;
$this
->
baz
=
'boom'
;
}
}
$data
= new
myClass
();
echo
http_build_query
(
$data
);
// foo=bar&baz=boom
?>
