Random link gösterme

Merhaba arkadaşlar.
Yine php ile alakalı bir sorunla buradayım

Sitemde random olarak link göstermek istiyorum fakat bir örneğini bulamadım.
Rand(0,3) gibi Google'da sonuçlar buldum ama bunu entegre edeceğim bir yer yok maalesef.

<a title="a" target="_blank" href="ahmet.html">a</a>
<a title="b" target="_blank" href="ali.html">b</a>
<a title="c" target="_blank" href="ayse.html">c</a>

Elimde yukarıdaki şeklin aynısı link var. Siteme koyduğumda sırayla a , b ve c olarak görünüyor. Ben bunları php ile sayfa her yenilendiğinde sırasını nasıl değiştirebilirim?

Yani b - c - a şeklinde listelenecek. c - b - a şeklinde olacak. Sayfa her yenilendiğinde sırası değişecek.

Yardımlarınız için şimdiden teşekkürler.

Buldum!
Lazım olan arkadaşlar için kod aşağıdadır.
