stringhttp_build_queryarrayformdatastringnumeric_prefixstringarg_separator
Generates a URL-encoded query string from the associative (or indexed)
array provided.
&reftitle.parameters;
formdata
May be an array or object containing properties.
The array form may be a simple one-dimensional structure, or an array
of arrays (who in turn may contain other arrays).
numeric_prefix
If numeric indices are used in the base array and this parameter is
provided, it will be prepended to the numeric index for elements in
the base array only.
This is meant to allow for legal variable names when the data is
decoded by PHP or another CGI application later on.
arg_separator
arg_separator.output
is used to separate arguments, unless this parameter is specified,
and is then used.
&reftitle.returnvalues;
Returns a URL-encoded string.
&reftitle.changelog;
&Version;&Description;5.1.2
The arg_separator parameter was added.
5.1.3
Square brackets are escaped.
&reftitle.examples;
Simple usage of <function>http_build_query</function>
'bar',
'baz'=>'boom',
'cow'=>'milk',
'php'=>'hypertext processor');
echo http_build_query($data); // foo=bar&baz=boom&cow=milk&php=hypertext+processor
echo http_build_query($data, '', '&'); // foo=bar&baz=boom&cow=milk&php=hypertext+processor
?>
]]>
<function>http_build_query</function> with numerically index elements.
'milk', 'php' =>'hypertext processor');
echo http_build_query($data) . "\n";
echo http_build_query($data, 'myvar_');
?>
]]>
&example.outputs;
<function>http_build_query</function> with complex arrays
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)
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.
Using <function>http_build_query</function> with an object
foo = 'bar';
$this->baz = 'boom';
}
}
$data = new myClass();
echo http_build_query($data); // foo=bar&baz=boom
?>
