ขอถามเกี่ยวกับ การตั้งชื่อไฟล์คับ อยากให้ช่วยอธิบายหรือช่วยแนะนำโค้ดคับ เพราะไม่มีความรู้เรื่องนี้เลย |

คือได้โค็ดมาอัพโหลดรูปมา แต่ระบบเป็นการเปลี่ยนชื่อที่อัพเข้าไปแบบสุ่ม อยากจะให้ต่อท้ายด้วยชื่อของมันเองก่อนอัพโหลดเข้าไปคับ
เช่น http://localhost/hot/i/ud.jpg แต่อยากให้มันเป็น http://localhost/hot/i/ud/1234567.jpg
(1234567.jpg เป็นชื่อไฟล์ที่อัพเข้าไป) พอดีไม่มีความรู้เรื่องโค็ดเลยแต่งมเอา อยากให้ช่วยแนะนำโค็ดให้หน่อยคับ

ใช้การสุ่มชื่อครับ หรือจะใช้วันเดือนปีชั่วโมงนาทีวินาทีก็ได้ครับ
Code (PHP)
$filename = date("YmdHis").".jpg";

บางครั้งการตั้งชื่อไฟล์แบบนี้มันสามารถช่วยตรวจสอบอะไรได้หลาย ๆ อย่างครับ

ปัญหาก้อคือว่า เวลาเรา ต้องการใช้งานไฟล์จะหาไม่เจอเพราะชื่อมันแรนดอม สุ่มออกมาให้คับ เลยต้องการโค้ดทำให้ชื่อที่เราตั้งต่อท้ายชื่อที่สุ่มมาคับ ตัวสุ่มทำได้แล้วคับติดตรงชื่อที่เราตั้งอยากให้ต่อท้าย เพื่อจะได้หาง่ายๆ
เช่น http://localhost/hot/i/ud.jpg
http://localhost/hot/i/se.jpg
http://localhost/hot/i/0u.jpg
http://localhost/hot/i/u694.jpg
http://localhost/hot/i/fwe5.jpg
แต่อยากให้มันเป็น http://localhost/hot/i/ud/1234567.jpg
http://localhost/hot/i/se/scs12345678.jpg
http://localhost/hot/i/0u/sdf1234569.jpg
http://localhost/hot/i/u694/aa1234565.jpg
http://localhost/hot/i/fwe5/cc1234.jpg
ชื่อไฟล์ที่อัพเข้า
scs1234567.jpg
sdf12345678.jpg
aa1234569.jpg
bb1234565.jpg
cc1234.jpg
