获取数组的最后一个元素，而不更改其内部指针

Question

How can I get the last element of an array without changing its internal pointer?

What i'm doing is:

while(list($key, $value) = each($array)) {  
    //do stuff  
    if($condition) {  
        //Here I want to check if this is the last element of the array            
        prev($array);  
    }  
}

so end($array) would mess things up.

It's simple, you could use:

$lastElementKey = end(array_keys($array));
while(list($key, $value) = each($array)) {  
    //do stuff  
    if($key == $lastElementKey) {  
        //Here I want to check if this is the last element of the array            
        prev($array);  
    }  
}
