Kumpulan Function PHP untuk Webmaster

Function adalah kode program yang di buat khusus untuk mempersingkat sebuah fungsi yang ingin di lakukan di dalam sebuah penulisan kode program, dan function dapat di panggil berkali-kali untuk melakukan fungsi tertentu dalam penulisan kode program.

Berikut admin lampirkan kumpulan function yang paling dicari webmaster.

## IMPLEMENTASI
// FORMAT "2019-01-17 09:09:09"
echo timeAgo($time_ago);
output : 11 months ago

Itulah beberapa fungsi php yang bisa admin tulis pada tulisan kali ini. Mudah-mudahan anda mencari function serupa. Salam barbar!
