PHP แก้ไข Warning: Invalid argument supplied for foreach()

กระทู้คำถาม

PHP MySQL SQL CSS HTML5

ตอนนี้พยายามจะแก้ไข โค๊ด error โดยมันแสดง error
โดยถ้าอัพโหลดภาพที่มี gps ไม่แสดง error แต่ถ้าอัพภาพที่ไม่มี gps มันจะแสดง error
Notice: Undefined index: GPSLatitude in C:\xampp\htdocs\testgps\insert.php on line 67
Notice: Undefined index: GPSLatitudeRef in C:\xampp\htdocs\testgps\insert.php on line 67
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\testgps\insert.php on line 59

Notice: Undefined offset: 2 in C:\xampp\htdocs\testgps\insert.php on line 63
Notice: Undefined index: GPSLongitude in C:\xampp\htdocs\testgps\insert.php on line 68
Notice: Undefined index: GPSLongitudeRef in C:\xampp\htdocs\testgps\insert.php on line 68

Notice: Undefined offset: 2 in C:\xampp\htdocs\testgps\insert.php on line 63

แต่พอนำ error_reporting( error_reporting() & ~E_NOTICE ); มาใส่ ไม่แสดงerror เหลือแต่
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\testgps\insert.php on line 59
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\testgps\insert.php on line 59
พอจะมีแนวทางแก้ไขยังไงบ้าง
ตัวอย่างโค๊ด
