$arr=array(6,3,53,5,3);
$arr2=array();
foreach($arr as $v){
if(!in_array($v,$arr2)){
$arr2[]=$v;
}
}
var_dump($arr2);
?
$arr2即为除掉重复值的结果
array_unique() 函数定义和用法
移除数组中的重复的值，并返回结果数组。
当几个数组元素的值相等时，只保留第一个元素，其他的元素被删除。
返回的数组中键名不变。
例子
?php
$a=array("a"="Cat","b"="Dog","c"="Cat");
print_r(array_unique($a));
?
输出：Array ( [a] = Cat [b] = Dog )
