http_build_query

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

 

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

 

Note:只有基础数组中的数字下标元素才获取了前缀,其它数字下标元素则不需要为了合法的变量名而加上前缀。

 

注意,http_build_query() Returns a URL-encoded string.

(今天在做一个接口的时候,发现重复编码2次,一直找不到问题...后来发现其中一次是在此处...)

 

mixed $query_data:object

<?php
class parentClass {
    public    $pub      = 'publicParent';
    protected $prot     = 'protectedParent';
    private   $priv     = 'privateParent';
    public    $pub_bar  = Null;
    protected $prot_bar = Null;
    private   $priv_bar = Null;

    public function __construct(){
        $this->pub_bar  = new childClass();
        $this->prot_bar = new childClass();
        $this->priv_bar = new childClass();
    }
}

class childClass {
    public    $pub  = 'publicChild';
    protected $prot = 'protectedChild';
    private   $priv = 'privateChild';
}

$parent = new parentClass();

echo '$parent->pub = ' . $parent->pub;
echo '<br>';
echo '$parent->pub_bar->pub = ' . $parent->pub_bar->pub;
echo '<br>';
echo urldecode(http_build_query($parent));
?>

//结果 权限问题,最终打印出的是public的内容。
$parent->pub = publicParent
$parent->pub_bar->pub = publicChild
pub=publicParent&pub_bar[pub]=publicChild
