PHP使用http_build_query()构造URL字符串的方法(可将POST参数组转换拼接成GET请求链接)

http_build_query

(PHP 5, PHP 7)

http_build_query — 生成 URL-encode 之后的请求字符串

 

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

echo http_build_query($data);
/* 
 * 输出：foo=bar&baz=boom&cow=milk&php=hypertext+processor
*/
?>
例子 2. http_build_query() 使用数字下标的元素

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

echo http_build_query($data);
/* 
 * 输出：0=foo&1=bar&2=baz&3=boom&cow=milk&php=hypertext+processor
*/

echo http_build_query($data, 'myvar_');
/* 
 * 输出：myvar_0=foo&myvar_1=bar&myvar_2=baz&myvar_3=boom&cow=milk&php=hypertext+processor
*/
?>
