The example in this article describes the implementation method of PHP recursive json class. Share it with everyone for your reference.

The specific implementation code is as follows:

Copy code The code is as follows:

/*

*/
class json{
private $Arr = array(); //Pass in array
//Constructor
public function json($array)
{
if(!is_array($array)) return false;
$this->Arr = $array;
}
//Analyze the main function
public function MainArr()
{
$arr = $this->Arr;
if($this->TypeArr($arr))
{
$json = $this->NumArr($arr);
}
else
{
$json = $this->IndexArr($arr);
}
Return $json;
}
//Parse the index array
public function IndexArr($arr)
{
$str ="";
foreach($arr as $k=>$value)
{
if(is_array($value))
{
If($this->TypeArr($value)) { $sun=$this->NumArr($value);}
else else {$sun=$this->IndexArr($value);}
If(strpos($sun,"}") || strpos($sun,"]"))
{
$str .= """.$k."":".$sun.",";
}
else
{
$str .= """.$k."":"".$sun."",";
}
}
else
{
$str .= """.$k."":"".$value."",";
}
}
$str = "{".trim($str,",")."}";
Return $str;
}
//Parse the numeric array
public function NumArr($arr)
{
$str = "";
foreach($arr as $value)
{
if(is_array($value))
{
If($this->TypeArr($value)) { $sun=$this->NumArr($value);}
else else {$sun=$this->IndexArr($value);}
If(strpos($sun,"}") || strpos($sun,"]"))
{
$str .= $sun.",";
}
else
{
$str .= """.$sun."",";
}
}
else
{
$str .= """.$value."",";
}
}
$str = "[".trim($str,",")."]";
Return $str;
}
//Check whether an array is strictly numerically indexed
public function TypeArr($arr)
{
if(array_values($arr) === $arr) return true;
return false;
}
}
?>
