http_build_query的使用方法

string http_build_query ( mixed $query_data [, string $numeric_prefix [, string $arg_separator [, int $enc_type =PHP_QUERY_RFC1738 ]]] )

使用给出的关联(或下标)数组生成一个URL-eccode请求的字符串

使用方法:

$data = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&');

//会输出:
  foo=bar&baz=boom&cow=milk&php=hypertext+processor
  
  foo=bar&baz=boom&cow=milk&php=hypertext+processor

如果数组不带key,则以下标的默认数字下标作为生成的URL-encode的key:

$data = array('foo', 'bar', 'baz', 'boom', 'cow' => 'milk', 'php' =>'hypertext processor');
echo http_build_query($data) . "\n";
echo http_build_query($data, 'myvar_');

//输出
   0=foo&1=bar&2=baz&3=boom&cow=milk&php=hypertext+processor
   myvar_0=foo&myvar_1=bar&myvar_2=baz&myvar_3=boom&cow=milk&php=hypertext+processor
