รอคำตอบเพิ่มด้วยคนค่ะ เพราะ array ถือว่าสำคัญมากๆเลย
ขอบคุณด้วยนะคะ :wink:

เจ้าของกระทู้ลองใส่แท็ก <pre></pre> คร่อมตอน print_r() จะช่วยให้เห็นภาพชัดขึ้นนะครับ

เช่น

echo '<pre>', print_r($array,true),'</pre>';

$level[] = $value->level;  

if(!in_array($value->level, $level)) {
 $level[] = $value->level;
} 

แทน
[code=php]$level[] = $value->level;  [/code]

ด้วย
[code=php]if(!in_array($value->level, $level)) {
 $level[] = $value->level;
} [/code]

แล้ว ลอง print_r กับ array_unique ไปอยู่ นอก loop
print_r($level_menu);

       if($this->config['m_main_menu_enable']){
                                $gat_path_url_json = file_get_contents($this->config['m_main_menu_path']);
                                $data  = json_decode($gat_path_url_json);
                                $level  = array();
                          
                                foreach ($data as $key => $value) {
                           
                                        $level[] = $value->level;
                                        $level_menu = array_unique($level); //  หา level ของ menu ว่ามี level อะไรบ้าง 
                                        print_r($level_menu);
                                    
                                }  
                        }

file_get_contents มาจาก json
[code] if($this->config['m_main_menu_enable']){
$gat_path_url_json = file_get_contents($this->config['m_main_menu_path']);
$data = json_decode($gat_path_url_json);
$level = array();

foreach ($data as $key => $value) {

$level[] = $value->level;
$level_menu = array_unique($level); // หา level ของ menu ว่ามี level อะไรบ้าง
print_r($level_menu);

}
}[/code]

ตัวแปล สร้างมา ยังไง ครับ
ลอง เอาตัวแปลมาดูหน่อย

        $level  = array();
                
                                foreach ($data as $key => $value) {

                                        $level[] = $value->level;
                                        $level_menu = array_unique($level); //  หา level ของ menu ว่ามี level อะไรบ้าง 
                                        print_r($level_menu);
              
                               
                                }
