关于这两个函数他们有一个区别就是mt_rand效率要高到rand哦。
mt_rand与rand函数区别与实例
下面我们来看看mt_rand函数的实例吧。
function roll () {
return mt_rand(1,6);
}
echo roll();
function roll ($sides) {
return mt_rand(1,$sides);
}
echo roll(6); // roll a six-sided die
echo roll(10); // roll a ten-sided die
echo roll(20); // roll a twenty-sided die
再看一个rand函数的实例吧。
function cn111 () {
return rand(1,6);
}
echo cn111();
