以下是三零網(wǎng)為大家整理的最新php遞歸json類分享的文章,希望大家能夠喜歡!在這里為大家?guī)硪黄猵hp遞歸json 類分享。希望對您的學(xué)習(xí)PHP有所幫助。

具體實現(xiàn)代碼如下:

<?php  

class json{

private $Arr = array(); //傳入數(shù)組

//構(gòu)造器

public function json($array) {

if(!is_array($array)) return false; $this->Arr = $array;

}

//解析主函數(shù)

public function MainArr()

{

$arr = $this->Arr;

if($this->TypeArr($arr)) {

$json = $this->NumArr($arr); }

else

{

$json = $this->IndexArr($arr); }

return $json;

}

//解析索引數(shù)組

public function IndexArr($arr) {

$str ="";

foreach($arr as $k=>$value)

{

if(is_array($value))

{

if($this->TypeArr($value))

{ $sun=$this->NumArr($value);} else {$sun=$this->IndexArr($value);} if(strpos($sun,"}") || strpos($sun,"]")) {

$str .= """.$k."":".$sun.",";

}

else

{

$str .= """.$k."":"".$sun."","; }

}

else

{

$str .= """.$k."":"".$value."","; }

}

$str = "{".trim($str,",")."}";

return $str;

}

//解析數(shù)字?jǐn)?shù)組

public function NumArr($arr) {

}

{
